Preparations for twisting peach leaves. Peach leaf curl

Many lovers peach trees know what curly is. This is the most common and most dangerous disease culture. The fungus infects leaves and shoots, greatly reduces the yield of peach and threatens it with death. However, the disease is not critical if detected early. There are several effective methods disease prevention and treatment.

Description and diagnosis of the disease

Leaf curl is a widespread and well-recognized disease of nectarines. Specifications:

• causative agent - marsupial fungus Taphrina deformans;
• time of infection - spring;
• spores live in the bark, penetrate the plant through wounds, cracks, buds;
• the infection development cycle ends in summer-autumn, new spores again settle on the trunk and move under the bark.

Attention! Leaf curl is dangerous annual shoots peach.

The disease is well diagnosed in the early stages:

Attention! The infection begins to infect the peach from the lower levels, moving along the shoots to new leaves. As a result, a small brush of intact greenery remains only at the end of each branch.

Attacked by curliness, young peach shoots turn yellow, become thicker, deform and also dry out. Internodes grow shorter and thicker. Buds on the branches, as a rule, remain. Only with a strong infection do they die off along with the rest of the peach greens. In the next season, the gardener will still miss the lion's share of the fruits that could be tied up on second-year shoots.

Curly Prevention

You can reduce the risk of peach infection even at the planting stage. The culture normally develops in areas well-lit by the sun, in places without stagnant moisture. It is undesirable to place a peach near other fruit trees. These measures will minimize the impact of negative factors:

• high humidity;
• cold snaps;
• temperature fluctuations.

In the spring, the influence of dangers is great. At this time, you need to start the preventive treatment of peach:

• a solution of 1% copper sulfate;
• a solution of 3% Bordeaux mixture;
• or a fungicide of your choice - Hom, Skor, Raek (according to the instructions).

Spraying is carried out twice a year: in the fall - after the foliage has fallen, in the spring - before it appears. If the disease has already taken over your area, schedule another peach treatment in the spring, 5 days after the first. Spray technology is standard. Do not perform the procedure in windy or rainy weather.

Advice. Autumn spraying is combined with pruning. Be sure to remove and burn the affected parts of the peach. The foliage from such a tree is also burned.

The method of treating the disease

If the disease has already attacked the peach, get ready for a laborious treatment. Methods for combating leaf curl during its intensive development are approximately as follows:

Folk experience in the fight against curly hair

Folk remedies are ineffective in the fight against a serious illness. But in the early stages of a disease or to reinforce the action of a fungicide, they are sometimes used. Tobacco infusion is popular against leaf curl:

• dried tobacco (1 kg) stir in boiling water (5 l);
• leave covered for 3 days;
• strain;
• dilute with water in a ratio of 1:2.

Advice. The peach orchard is sprayed twice with an interval of 2 weeks.

Also use lime emulsion:

• thoroughly mix softened clay (350 g) in water (10 l);
• continuing to stir, add slaked lime (90 g);
• achieve uniformity of the solution, there should be no sediment.

The emulsion is not stored. Spend it completely on spraying. To achieve the result, carry out the treatment several times.

Peach is a capricious crop. Gardeners say: if the dosage or frequency of use of drugs is incorrectly calculated, the plant may react in an unexpected way - shed leaves, flowers, fruits, or even dry out.

Peach is not often seen in country gardens, like the same apple trees or pears, since this fruit crop is very capricious in care and requires heightened attention. In order for the tree to bear fruit regularly, it is necessary to properly care for it, including the mandatory spring processing of peach in the spring from all kinds of diseases (especially against leaf curl) and pests.

Why spring peach processing is needed: main diseases and pests

In order for the peach to be able to recover faster after the winter in spring and enter the growing season in a timely manner, it is necessary to provide him with maximum care and attention from the first days.

The beginning of spring is a period of awakening not only of plants, but also of the worst enemies of culture: wintering pest larvae and fungal spores. But before you carry out proper care and process the peach in the spring, you need to recognize the enemy (all diseases and pests of the crop) “by sight”.

Diseases

Spring peach processing is carried out against the following fungal diseases:

• - the most dangerous disease of this culture.

Infection occurs during swelling of the kidneys.

First, it affects young, freshly blossomed leaves, on which amber or red-pink bumpy spots appear (their surface becomes uneven and wavy). And after a couple of weeks, a white waxy coating forms on the underside of the leaf - this is the fruiting of the fungus. In the future, such leaves turn brown and fall off.

Exposure of the affected shoots begins, as a rule, from below. From this, they take the form of a brush, thicken, bend, acquire a yellowish tint. After that, starting from the top, part of the shoots exposed as a result of leaf fall dries up, the rest die at the first frost.

Fruits developing on two-year-old shoots affected by curlyness fall off.

• Clasterosporiasis (perforated spotting).

• Moniliosis (fruit rot) and monilial burn.

Note! The site already has content. .

• powdery mildew- one of the most common problems (along with moniliosis = fruit rot) of all stone fruits. It affects foliage, shoots and fruits, manifesting itself as a dirty white (yellow) coating.

Rarely enough, peach trees pick up scab.

Pests

The most first treatment of peaches from pests carried out against the following wintering stages of insect pests:

• scale insects;
• worm;
• ticks;
• sucker and other sucking and leaf-eating pests.

Second and subsequent peach treatments are already carried out against such pests as:

• Flower weevils- affects buds, buds and flowers. In addition, they are carriers of many fungal diseases.

• Aphid- affects young foliage and shoots, feeding on their juice. It multiplies rapidly and forms numerous colonies. In the absence of protective procedures, it can cause serious harm to the culture and significantly slow down its development.

Typically found on peaches blood aphid.

• Mite. Requires special treatment with acaricides. With a large number, it can greatly weaken the immunity of the plant.

• Mining moth.

• Eastern codling moth.

The main stages and terms of processing peach from diseases and pests: when to spray

It is very important not to be late and to carry out the first early spring peach processing on time. However, don't be in too much of a hurry. If there is still snow outside the window or the weather is unstable: there are often precipitations - rains, sleet, fog, then spraying at this time will simply be ineffective.

Thus, when stable warm (+4..5 degrees during the day and not lower than 0 at night) and dry weather sets in, it will be possible to make the first treatment.

Note! If you did not have time to do this in the fall (and you should have), then at the end of winter in early spring(in February-early March) highly desirable to whitewashing trunks and low skeletal peach branches. This treatment will protect your fruit trees from the sun (ultraviolet) rays and sudden changes temperatures in the winter-spring period, which will prevent the appearance of cracks on them, into which various infections (fungal spores) and pests can no longer get.

By the way! About, how to whitewash fruit trees (including peaches) in autumn and spring, read .

It is quite obvious that in different dates various diseases and pests appear. Accordingly, each phase of peach development should have its own specifics of its processing. At the same time, it is very difficult to name specific dates, it is much easier and more correct to focus specifically on the phases of development (vegetation) of a peach tree in the spring.

So, there is a certain scheme for processing the garden in the spring, according to which spraying is carried out at the following stages of development (vegetation) of the peach:

It is necessary to process a peach in the spring from diseases and pests at least 4 times, which guarantees the protection of the crop and a wonderful harvest.

• Before awakening or bud break, when they are still sleeping.

This treatment is also called "early spring spraying", and more often spraying "on a bare tree", because. at this time, no signs of awakening (vegetation) have yet appeared on the peach.

By the way! Instead of treating dormant buds, some gardeners spray on those that have already begun to swell (wake up)

• "Green Cone" When the buds are already swollen and burst, but the leaves have not yet appeared (turned around).
• "By rose buds". Also called the stage of "promotion or separation of buds."

Interesting! Sometimes the treatment is carried out directly during flowering, but only against diseases.

• "On the ovaries with a pea." In other words, after flowering, when small ovaries are already formed.
• In the future (already in the summer), at the stage of growth and fruit formation, it is also necessary to carry out preventive and therapeutic treatments (if you do not want to use chemicals, then at least spray with biological preparations).

• In the fall (after leaf fall), it is necessary to carry out an autumn eradicating spraying (copper or iron sulfate, Bordeaux liquid).

Video: spraying scheme for peaches and other fruit trees in spring

Important! If it seems to you that it is unrealistic to carry out such a number of treatments, then this is not at all the case, even if you are in the country only on weekends (1-2 days a week). Each stage does not last one day, but about a week or more. In addition, you can track all the stages on the city trees.

Before awakening of the kidneys or early spring spraying "on bare trees"

For the first time, it is necessary to process a peach in the spring from diseases and pests. before bud break while they are still dormant.

Spray the peach in the spring, before the awakening (blooming) of the buds, you should only at positive air temperature not less than +4..+5 degrees.

The first spray is often called "extirpating" since this treatment allows you to get rid of most of the wintering stages of insect pests, as well as from the spores of some fungal diseases.

Moreover, it is important to spray not only the peach trees themselves (trunks and branches), but also the soil at their base., since many pests and pathogens are also concentrated there, which, when higher temperatures are established, will begin to attack young leaves and shoots.

Typically, during this period the simplest means of contact. For example, to choose from: Bordeaux liquid, copper or iron sulfate mixed with urea.

And you can use special preparation against wintering stages of pests- "Prophylactin" or "Preparation 30 Plus".

Spraying in the "green cone" stage

The second treatment of peaches in the spring against diseases and pests should be carried out during the period of swelling and bud break, in other words, in the “green cone” stage.

This phase is characterized by the fact that the buds on the trees have already burst, but the leaves have not yet unfolded, although they are already clearly visible (hence the “green cone”).

Note! Spraying in the "green cone" phase is considered the most important and most favorable period for the treatment of peach from diseases and pests.

Important! If for some reason you did not carry out the processing at the previous stage, then it is better hurry up, insofar as the duration of this phase (“green cone”) is relatively short. Moreover, if the weather is good sunny, the temperature is stable above +10 degrees, then the kidneys will open quickly enough.

At this stage, usually more serious means are being used:

• against clasterosporiasis - Horus or Skor (or its full analogue Rayok);

Important! Chorus must be used at temperatures up to +15 degrees, Speed ​​(Rayok) - above +15.

• leaf curl - Horus or Skor.

Contact fungicidal preparations can also be used against copper based

Specificity! For instance, Horus works great at low positive temperatures (about +4..+5, but up to +15), a Skor or Rayok on the contrary, it works better at more high temperatures(from +10..+15). Therefore, at the stages before budding and flowering (in the “green cone” phase), it is desirable to spray with Horus, and Skorom - already at the “rose bud” stage and after flowering (“pea-sized ovaries”).

It's time to start fighting with flower beetles (weevils), for example, Aktara.

But, if you missed the previous processing, then at the stage of the "green cone" it is still possible to spray the peach Bordeaux liquid or one of the solutions based on copper or iron sulphate with urea(See more details in the paragraph "Tank mixtures"). And also apply against overwintering stages of pests a special drug - "Prophylactin" and "Preparation 30 Plus".

By the way! blue vitriol and Bordeaux liquid, which also contains copper, perfectly protect against leaf curl.

At the same stage for additional protection peaches from pests You can put on stamps trees special trapping belts, build and hang on branches glue traps, pheromone houses.

Spraying in the stage of budding or in the phase of "rose bud"

The third stage of the processing of peaches in the spring from diseases and pests is carried out at the stage when the bud has already formed and advanced (it is pink), but has not yet opened.

Interesting! At this time, it begins its activity (to lay eggs) codling moth.

At this stage, spraying should be carried out against the following diseases:

• leaf curl - Horus, Skor, Delan;
• monilial burn— Horus;
• powdery mildew - Topaz.

Also against clasterosporiasis and curliness copper based, for example, Abiga-peak, Hom, Polyhom.

As far as pest control is concerned,

• against flower beetle - Aktara, Karate Zeon;
• aphids, copperheads- Aktara;
• ticks- Karate Zeon;
• leaf rollers - Insegar, Voliam Flexi;

You can use any similar means aimed at the listed pests, the above is just an example.

Temperature conditions at the stage of "rosebud", as a rule, improve, the weather it is warm and sunny (temperature + 10-15 degrees and above), which means you can start using biological drugs(see separate paragraph "Biopreparations").

Video: peach processing in the rosebud phase

Spraying after flowering "by ovaries with a pea"

Immediately after flowering, when small ovaries are already formed, it is necessary to produce complex treatment of peaches as from diseases(especially against moniliosis) and against pests(especially from codling moth).

Spraying should be carried out with similar preparations:

• against clasterosporiasis - Horus, Skor;
• leaf curl - Horus, Skor;
• monilial burn - Horus;
• powdery mildew - Topaz;
• moniliosis (fruit rot)— Horus.

Also against clasterosporiasis and curliness fungicides can be used copper based, for example, Abiga-peak, Hom, Polyhom.

As far as pest control is concerned,

• against aphids, suckers - Aktara, Voliam Flexi;
• ticks - Karate Zeon, Vertimek;
• leaf rollers - Insegar, Voliam Flexy, Lufox, Prokleim;
• mining moth - Insegar, Prokleim.
• codling moths - Insegar, Lufoks, Voliam Flexi, Prokleim, Match.

Advice! If some leaves still pick up curl, then they will need to be removed manually.

How to properly spray a peach in spring

• During the preparation of solutions and spraying trees observe safety precautions. If the product packaging says that you need to wear special clothing (robe, overalls, raincoat), goggles and a respirator, rubber gloves, then you need to wear it.

• Processing should only be in dry and calm weather.

V sunny weather it is better to refrain from spraying, because, quickly drying out, the drugs become ineffective or do not work at all. Spraying is best done in cloudy, calm weather, but also not by rain: after the rain, the branches are wet, as if a thin “film” of water is on them. And spraying is droplets of the solution, which in the same way cover the plant with a thin “film” of drops. If processing is carried out, the concentration of the solution will decrease, and the processing efficiency will decrease.

• Spraying is desirable in the morning (after the dew has dried) or late evening (after sunset).

Too much early processing will be ineffective due to non-evaporated dew and high humidity air.

• Processing is always carried out exactly after, in order to further protect the cut points (ideally, if you sprinkle them with copper sulphate or Bordeaux liquid, in other words, if there is copper in the fungicide).

By the way! Some gardeners believe that the simplest and most economical remedy is correct pruning. So, at the end of the first pruning, before bud break, you need to cut all annual branches 2-3 buds from the top. Most of all fungal spores hibernate in them. This is the most unripe and painful part of the plant. From here comes the infection of healthy parts of the peach. Sometimes this procedure is enough to prevent curly hair from appearing.

• It does not follow carry out spraying against pests during the flowering period(may harm bees and other pollinators) only for diseases.
• All prepared solutions should be pass through a filter mesh so as not to clog the sprayer.
• Suitable for dissolving almost all drugs room temperature water(for vitriol it is desirable to use hot water, about + 40-50 degrees).

And if you are using a biological product, then water better to take settled or filtered, i.e. without chlorine.

• At each stage, you can use like the same drugs(to save money) and new (better change the active substance so that there is no addiction - it will be more effective), or alternate(use alternately).

During each phase, you can carry out not 1, but 2 or more treatments, if it is indicated in the instructions for the drug, especially after flowering.

• It is possible to prepare tank mixtures that will have insecticidal-fungicidal properties (in this case, it is necessary to clarify the compatibility of drugs).

But! Some agronomists believe that do not immediately give a double chemical load on the plant. It is better to take a break for at least 1 day (for example, on Saturday morning, treat with a fungicide, and on Sunday morning with an insecticide). It is also possible to spray with an interval of 1 week, i.e. on one weekend they were treated for pests, the next - for diseases (or vice versa).

The specifics of the processing of adult (old) and young trees

Naturally, adult fruit-bearing peaches need to be fully processed in the spring, i.e. in 4 stages.

Another thing, while the tree does not bloom and bear fruit, it is obvious that insects stick to it less. Therefore, it will be enough to process young peach trees only 3 times:

1. on dormant buds from diseases and wintering pests;
2. "on a green cone" from insect pests;
3. after flowering, when pea-sized ovaries are formed, from diseases (especially against monilial burn).

Note! peach is one of the fastest growing fruit crops, which starts fruit already 3rd year after planting.

How to treat peach in the spring from pests and diseases: the best preparations

For spring processing garden exists a large number of funds, but how exactly to process a peach in the spring from diseases and pests, before proceeding with the procedure, you need to decide in advance. As well as how to use drugs, in what quantity to use them. Next, we will analyze this issue in more detail.

Note! At each stage, you can use both the same drugs (in order to save money), and new ones (and it is better to change the active substance so that there is no addiction - it will be more effective), or alternate (use alternately).

Important! The instructions for each drug always indicate when (at what time) and how many times they need to process.

So, for effective spring processing of peaches, you will need:

• fungicides (drugs to fight diseases);

By the way! In this case, fungicides are divided into preparations protective (preventive) and curative action, as well as protective-healing.

Of course, it is optimal to use complex drugs that have protective and therapeutic effects.

Accordingly, if you noticed signs of illness, then no preventive (protective) means will help you, only treating (or protective-treating).

• insecticides (means for combating insect pests);
• insectofungicides (complex preparations that act simultaneously against pests and diseases).

By origin, these products (fungicides and insecticides) can be:

• chemical (those same "chemicals");
• biological (biological products).

Of course, there are also folk remedies, For example, various solutions and infusions based on herbs, etc. But their effectiveness is very, very limited.

Chemicals and Biologicals

Note! Many gardeners have a preconceived notion that the use of chemicals is negatively reflected (carries Negative consequences) on the quality of the future crop and human health. However, this is not true, since after the expiration of the waiting period, all harmful substances(pesticides) are excreted long before fruit ripening and harvest.

Unlike biopreparations, chemical agents act much faster and more reliably. In addition, the use of chemicals is very often the only way cure the culture of fungal diseases and get rid of annoying pests.

TO Of course, at the same time, it is imperative to fully comply with the recommendations on their dosage and timing of spraying.

Whereas biological preparations and folk remedies have a more gentle effect, which is permissible only in the following cases:

• with a small number of pests;
• on the initial stage development fungal disease or a mild infection, and even better as a prophylaxis (protection), but not an active fight.

Fungicides (chemical)

As for preparations suitable for spring spraying of peaches against diseases, the following can be used fungicides(chemical agents for combating fungal diseases of plants):

Important! For one treatment, you need to choose only one preparation (fungicide), and then use a new one (preferably with a different active ingredient), or alternate.

• Bordeaux mixture ( contact fungicide, 3% solution of Bordeaux liquid - before bud break and 1% - in the "rose bud" stage - from clasterosporiosis, curliness and moniliosis);

• Copper vitriol ( contact fungicide, from clasterosporiasis, curliness and moniliosis);

• Inkstone;

About that, it is told in detail.

• Carbamide (urea);

Usually,

• Abiga Peak ( protective contact fungicide based copper oxychloride,

• Hom ( contact fungicide protective action based copper oxychloride against clasterosporiasis, moniliosis and curliness);
• Oksihom ( contact systemic fungicideprotective action based copper oxychloride and oxadixyl, against clasterosporiasis, moniliosis and curliness);

• Inkstone;

Advice! About, when, how and why to use iron sulphate, described in detail.

• Carbamide (urea);

Usually, urea is used together with copper or iron sulphate, namely, the tank mixture is being prepared.

• Thiovit Jet ( contact fungicide based sulfur, especially effective against powdery mildew and mites);
• Delan ( contact fungicide for protective and curative action based dithianon, against leaf curl, clasterosporiasis, scab);

• Forecast ( systemic fungicide protective and healing action based propiconazole

• Tilt ( systemic fungicide protective and healing action based propiconazole, against leaf curl, powdery mildew);
• Topsin-M ( systemic-contact protective fungicide action based Thiophanate-methyl, against scab, powdery mildew, fruit rot moniliosis and monilial burn, clasterosporiosis);

• Horus (based on cyprodinil, against moniliosis - fruit rot and monilial burn, clasterosporiasis, leaf curl);

• Speed ​​( systemic fungicide with protective and curative action based difenoconazole, against clasterosporiosis and leaf curl, as well as scab);

• Rayok ( systemic fungicide with protective and curative action based difenoconazole, against clasterosporiasis and leaf curl, as well as scab);

In fact, Speed ​​\u003d Rayok (its analogue).

Advice! Carefully study the instructions: the scope of the drug (against what diseases), terms, dosages!

Insecticides (chemical)

With regard to preparations suitable for spraying peaches in spring against pests, the following insecticides (pest control agents) can be used:

Important! For one treatment, you need to choose only one preparation (insecticide), and then use a new one (preferably with a different active ingredient) or alternate.

Active ingredients are listed in parentheses.

• Aktara ( Thiamethoxam (Aktara), systemic insecticide of intestinal-contact action, against flower beetle, sucker, aphids);

• Actellik ( Pirimiphos-methyl (Actellik), systemic insecticide of contact-intestinal action against ticks?);

Biological preparations of fungicidal and insecticidal action

Biological products are created on the basis of living organisms:

• mushroom antagonists;

• bacteria;
• bacterial viruses;

• beneficial insects (entomophages and acariphages).

Among biological products, fungicides, insecticides, and insectofungicides can be distinguished.

Note! As a rule, almost all biological preparations work effectively under the condition of a sufficiently high positive air temperature (+10 ... +15 degrees), so they begin to be used only at the “rose bud” stage, while the first and second treatments must be carried out using chemicals.

Biologicals fungicidal action(against diseases):

• Fitolavin (fungicide, for moniliosis = fruit rot);

• Alirin-B (systemic contact fungicide with protective and curative action, against powdery mildew, moniliosis);
• Phytosporin (contact fungicide, against powdery mildew, moniliosis, leaf curl);

• Planriz (contact fungicide, against moniliosis, leaf spots, including curl);

• Trichodermin or Trichoderma (fungicide, for moniliosis, leaf spots, including curliness);

Biologicals insecticidal action(against pests):

• Aktofit (insecticide, from codling moth, flower beetle, ticks, aphids, thrips);

Interesting! Aktofit is created on the basis of toxins of biological origin.

• Bitoxibacillin (from codling moth, leaflet, moth);

• Lepidocide (from codling moth, moth);

• Fitoverm ( Aversectin C, from codling moth, leafworm, ticks);
• Kleshchevit ( Aversectin C, from codling moth, leafworm ticks; ideal to spray after flowering);
• Gaupsin (insectofungicide of complex action, from moniliosis, leaf spots, including curliness, scab, powdery mildew, codling moth, aphids, leafworms and other pests).

Note! Yes, biologics have their advantages (they are environmentally friendly, have short term expectations), but it is worth recognizing that they are not as effective as chemical ones.

Tank mixes (fungicides + insecticides)

Note! Not all drugs can be mixed. For example, practically nothing can be mixed with Bordeaux liquid (it has an alkaline reaction).

The instructions should indicate which drugs they can be combined with.

For spring spraying peach (except for the first one, when the buds are still sleeping), you can prepare the following tank mixtures (fungicide + insecticide):

Chemical:

• Chorus (fungicide) + Decis Profi (insecticide);

At higher temperatures (+10..+15 degrees) Horus should be replaced with Skor(fungicide) + Decis Profi.

• Basically, you can replace Hyphen Profi with Aktara (insecticide): Aktara + Horus and Aktara + Speed

Engio- also works great in tandem with Horus or Skor.

• Speed ​​+ Topaz;
• Horus (or Skor) + Aktara + Karate Zeon;
• Bayleton (fungicide) + Karate (insecticide);
• Tilt (fungicide) + Caesar (insecticide);
• Skor (or Horus) + Caesar (insecticide).

By the way! It is believed that the tank mixture Skor + Horus will protect the peach from all major diseases by 99%.

Biological:

• Lepidocide + Bitoxibacillin + Gaupsin (insectofungicide)

Against leaf curl and other diseases:

• Planriz (fungicide) + Trichodermin (fungicide) + Pentafag-S (fungicide);
• Planriz (fungicide) + Trichodermin (fungicide) + Gaupsin (insectofungicide).
• Planriz (fungicide) + Pentafag-S (fungicide) + Gaupsin (insectofungicide).

Eradication spraying against diseases and pests

As an option, at the "green cone" stage or even earlier (when the kidneys are completely asleep) you can prepare the following solutions (tank mixes) for spring eradication spraying of peach against diseases and pests.

Let's be honest! Complete eradication of pests will not occur, but those that hibernate on the bark or in cracks (for example, the same scale insect) will suffer significantly if the solution enters.

Therefore, for the complete destruction of pests in the future, it is necessary to use other more serious and modern drugs.

• It is desirable to do the processing exactly according to the “green cone”, it is possible even earlier (when the kidneys are completely asleep), but not later.

But! If the leaves have already unfolded, then processing can still be carried out, but with certain restrictions. So, the concentration of solutions should be reduced by 2 times, i.e. either dilute with water 2 times, or reduce the amount of funds used by 2 times.

Recipe for a solution with copper sulphate

• Take 300 grams of copper sulfate and first dissolve in 1-1.5 liters hot water(40-50 degrees).

Note! Copper sulfate is not friendly with iron (iron objects), so use wooden and plastic sticks, as well as buckets (the same glass jars will do) to prepare the solution (stir it).

• Then pour the resulting concentrated solution into the sprayer, where there are already 8.5-9 liters of water.
• Next, pour a full 1-liter jar of urea (carbamide). If it seems to you that this is too high a concentration, then you can reduce the amount of urea to 500-700 grams.

Interesting! Treatment with urea along the "green cone" not only has a positive effect on the number of pests, but also delays flowering by 7-10 days. It is especially important that return frosts have time to pass before flowering.

• Add 200-250 ml liquid soap or dishwashing liquid.

Important! Laundry and any other solid soap is incompatible with a solution of both iron and copper sulfate (copper and iron simply precipitate). Therefore, it is necessary to use liquid soap, for example, any dishwashing detergent will do.

• To enhance the effect of copper sulphate, 30-50 ml of 10% ammonia (ammonia) should be added to the solution.
• Carry out eradicating spraying of trunks and branches.

The recipe for a solution with iron sulphate

• First, dissolve 20-30 grams in 1-1.5 liters of hot water citric acid.

By the way! Iron vitriol, when dissolved in water, oxidizes quite quickly (2-valent iron becomes 3-valent). To prevent this from happening, you need to add some kind of complexing agent to the solution (so to speak, chelate ferrous sulfate), for example, the same citric acid.

• Next, add 500 grams of iron sulfate to the resulting citric acid solution.

Note! For peach, which belongs to stone fruit crops (like apricot, plum, cherry plum, cherry, sweet cherry), it is recommended to prepare a 3% solution, i.e. you need 300 grams of iron sulfate.

But for the processing of pome crops (apple, pear, quince, chokeberry, mountain ash, grapes), it is recommended to prepare a 4-5% solution, that is, you need to add 400-500 grams of iron sulfate.

To destroy mosses and lichens on trees and garden tiles, as well as to treat the basement or cellar from mold, a 5-6% solution is prepared, i.e. 500-600 grams of iron sulfate

• Then you need to pour the resulting solution into the sprayer, where there are already 8.5-9 liters of water.
• Further, everything is similar to the previous recipe: add a full 1-liter jar of urea (carbamide) to the solution. If it seems to you that this is too high a concentration, then you can reduce the amount of urea to 500-700 grams.
• Add 200-250 ml of liquid soap or dishwashing detergent.
• Optionally, you can also take humates (according to the instructions).
• Mix everything thoroughly and shake.
• Carry out eradicating treatment of trunks and branches, as well as mosses in the garden (on the lawn), stones, foundations.

Folk remedies against pests

Folk remedies can be used as preventive measures to protect peach from pests. They are completely safe and environmentally friendly for both the garden and humans.

• Infusion of tobacco. To prepare the infusion, you need: pour 0.5 kg of dried tobacco into 10 liters of water and insist for 2 days. Then boil for an hour, again let stand for 1 day. Next, add 1 liter of infusion, 40 grams of soap to 10 liters of water and spray.

By the way! Alternatively, you can use tobacco dust.

• Infusion of chamomile officinalis. The mixture helps to scare away many pests. To prepare a working solution, pour 0.5 kg of dry plant collection with 5 liters of boiling water, leave to infuse for at least 12 hours. Grate 40 g into the resulting mixture laundry soap and add water to 10 liters. Strain and apply to spraying the trunk and crown.

• Decoction of hot pepper. It is recommended to use against pests. Pour dried pepper pods (100 g) with boiling water (1 l) and cook for 2 hours. Insist for two hours, then clean and add water to a total volume of 10 liters. Use for spraying shoots and leaves.

And let your peaches be like that!

Complete care for a peach in the spring it is impossible to imagine without the fight against pests and diseases, since the harvest can be obtained only if the tree is processed in a timely and high-quality manner. And what exactly to spray your peach trees with is your personal choice, just do not ignore the dosage and timing of spraying. And remember that peach processing in the spring is the most important crop protection measure that will allow you to get a rich harvest of tasty and healthy fruits.

In contact with

Peach curl is a common and very dangerous disease. In an infected tree, leaves and shoots are deformed, yield is reduced and development is slowed down. If you do not take action, the tree may die. We will learn how to recognize and cure this disease in time.

Of all the various diseases of the peach, curl is the most common. The causative agent of the disease is the fungus Taphrina deformans. In spring, it penetrates inside the tree through buds and microcracks on the shoots.

The fungus infects young leaves, most often aged 5 to 8 days, growing on one- and two-year-old shoots. Foliage that has already appeared two weeks ago can only get sick in rare cases. Infected leaves become a breeding ground for new spores that overwinter in the bark. In the spring, the infection cycle repeats. Favorable conditions for the development of the fungus are cool and high humidity.

Main features

The curl of peach leaves initially manifests itself as the appearance of small light green swellings. After a few days they turn red, then darken to brown. A waxy coating appears on the surface. The affected leaf thickens, dries up, gradually blackens, and finally falls off.

The disease primarily affects the lower leaves on the branch, then rises, so that as a result, only 2–3 leaves may remain at the top of the shoot. Tree branches also suffer: gum protrudes on them, they deform, thicken, turn yellow and die after a while. On new sprouts, the internodes are shortened and thickened, which worsens the yield. For extensive infection most of of flowers dies off without having time to form ovaries, and a few fruits turn out to be inedible due to rigidity and loss of taste. If the disease is not treated, the frost resistance of the peach will drop sharply and the tree may not survive the first winter.

Treatment and prevention

In the advanced stage, this infection is very difficult to cope with, so treatment should be started immediately after the first deformed leaves were found. The fight against peach curl begins with the removal of infected shoots. They must be cut and burned (preferably outside the site), and cover the wounds on the tree with garden pitch.

Then the peach should be treated with fungicides. This should be done before and after flowering. The tool "Skor" has proven itself well. It blocks the growth of fungal mycelium and to a small extent prevents the formation of spores. Doesn't wash off with rain. It works most effectively at a temperature of +14–25 °C. In addition to fighting the disease, it strengthens the plant's immunity and increases its yield. The preventive effect of the drug lasts 10 days, the therapeutic effect - 5. For the treatment of curliness, 2 ml of the drug is diluted in 10 liters of water. No more than 4 treatments are allowed per season.

Chorus goes well with Skor. Effective at temperatures from +3 to +20 ° C, two hours after treatment, it is not washed off by rain. It begins to act within 2-3 hours after spraying. Therapeutic effect lasts 36 hours, prophylactic - from 7 to 10 days.

Another popular remedy is Abiga-Peak. The drug inhibits the development and respiration of the fungus, suppresses many of its proteins, and is not addictive. It is slightly dangerous for bees (hazard class 3), moderately dangerous for humans. 4 treatments are allowed per season.

"Delan" effectively delays the germination and formation of spores. Doesn't wash off with rain. Not addictive. No more than 3 treatments can be carried out per season. Last time spraying the tree should be no later than 30 days before harvesting.

Of the biological agents, treatment with Planriz, Guapsin or Trichodermin is recommended. They do not harm other plants and do not accumulate in fruits. To reliably get rid of curliness, peach processing after flowering must be carried out several times: using one drug or alternating compatible ones.

You can spray peaches from leaf curl with a Bordeaux mixture. It gives a quick result, but has a number side effects, in particular, slows down the onset of the productive period and reduces the productivity of the tree. With regular treatments with this agent, copper accumulates in the shoots and leaves.

To combat the disease, folk remedies are also used. They do not act as effectively, therefore they are recommended for mild lesions or as an addition to chemicals. You can spray peach with tobacco infusion: tobacco or tobacco dust (1 kg) is poured with boiling water (5 l) and infused for 2 days. Before use, the strained infusion is additionally diluted with water 1: 2. Spraying should be repeated after 2 weeks.

Another method is the treatment of peach trees with an emulsion of clay (350 g) and slaked lime (90 g). Clay is stirred in 10 liters of water, then lime is added. The solution should be homogeneous, without sediment. Prevention primarily consists in choosing a dry, warm, well-lit place on the site for the seedling.

Twice a year, you need to treat the tree with one of the above drugs. Some gardeners also recommend a mixture of soda and copper sulfate as a preventive measure. The preparation method is as follows: a pack of baking soda and 300 g of vitriol are diluted in different containers with water, each 5 liters. Then the vitriol solution is poured in a thin stream into the soda solution - due to the violent reaction, this must be done very slowly and carefully. Timely sanitary pruning of the tree is important.

Fallen leaves should be removed in autumn: they serve as a breeding ground for all kinds of diseases.

Immune varieties

Unfortunately, there are no peaches that are completely resistant to this disease. However, some varieties resist kink better than others. These include: Early Kuban, Juicy, Kievsky 12, Yellow, Saturn, In memory of Rodionov, Favorite Morettini.

From this video you will learn how to properly deal with peach leaf curl.

Leaf curl is a scourge of gardeners when growing peach or nectarine. The insidious disease develops rapidly and it is very difficult to contain it. A gardener who decides to grow a peach on his site should know the causes and signs of leaf curl, as well as methods of prevention and treatment.

Peach leaf curl - characteristics and causes

This is the most dangerous and harmful peach disease, which, without appropriate prevention, in most cases leads not only to crop loss, but also to the death of trees.

Characteristics and causes of the disease

The causative agent of the disease is the fungus Taphrina deformans. It can also settle on apricot, nectarine and almond. Its spores hibernate in bark cracks, between bud scales, in affected leaves and shoots. In spring, when the air temperature reaches +10 °C, the spores germinate and form a mycelium. The active period of disease development coincides with the awakening of leaf buds and their blooming. It is the young leaves that are affected by the fungus in the first place. They are followed by young shoots and sometimes flower buds and flowers. The fruits are rarely affected. In summer, when the temperature rises above +26 ° C, and the leaves become coarse, the likelihood of infection decreases.

Symptoms of the disease look like this:

Methods of prevention and treatment

There are two principles of treatment and prevention of fungal diseases. First, you need to remove pathogens and mycelium from the diseased plant as much as possible - for this, diseased shoots, leaves, ovaries and fruits are cut off, after which they are disposed of. The operation, if necessary, is repeated during the growing season. The second necessary action is fungicide treatments (preparations for combating fungal diseases) in order to completely destroy the remaining fungi. And besides, we must not forget about typical preventive measures: autumn digging soil trunk circles, collection and disposal of fallen leaves, sanitary pruning, lime whitewash branches and trunks, as well as providing balanced nutrition and watering.

Processing peach from curly

Without timely treatments for curliness, it is most likely not possible to grow a healthy peach.

Most likely, it will not be possible to grow a healthy peach without timely treatments for curliness.

Processing times

The basis of preventive treatments are uprooting treatments of plants. They are carried out with potent drugs, as a rule, of universal action (from all diseases and pests). Since such drugs are quite toxic, and can also burn foliage and young shoots, they are used in late autumn (after the end of leaf fall) and (or) early spring (before bud swelling), when the tree is at rest.

How to spray peach from leaf curl

Manufacturers offer many different preparations for these purposes. Folk methods in this disease are ineffective, so we will not dwell on them. We will briefly introduce the most popular and effective fungicides, bringing the data into a table for the convenience of the gardener.

On sale you can find a large number of fungicides of various trademarks. It often happens that under different names hide the same drugs that have the same active ingredient in the composition. The gardener needs to know that most antifungal drugs cause fungi to become addicted to them and after several times of use their effectiveness decreases sharply. Therefore, during treatment, drugs should be alternated, not using the same (with the same active substance) more than the allowable number of times (the requirement does not apply to biological products). For this purpose, the table shows the names active ingredient each drug.

Leaf curl is a common disease of many agricultural plants and trees. The peach is no exception and, being prone to this disease, can lose a very significant part of the fruit. It is wrong to think that this is only an aesthetically noticeable peach disease - leaf curl causes damage to the shoots, which are deformed, and can lead to the death of the tree, not to mention losses in yield. In this regard, at the first signs of the disease fruit tree treatment measures must be taken.

How is the disease manifested and what is dangerous

Provokes curly hairy fungus in the period early spring. This usually occurs in conditions of high humidity and low temperature. Just at this time, the tree buds, and the spores are activated and start the process of developing diseases that the peach cannot resist. Leaf curl, which should be controlled already at early stages, is eliminated precisely by the destruction of the fungus. If appropriate measures are not taken, the infection affects all leaf buds against the background of marsupial sporulation of the fungus.

The development of the disease begins with the fact that the leaves turn pale, after which they change their shade to a reddish color. From this moment, the peach leaf curl begins. Treatment should begin at the first symptoms, but sparing means. If you start the disease, then the curl will hit the shoots, and eventually the ovaries. Peach fruits harden, lose taste qualities and become inedible. If the disease is not fought for several years, then in addition to the loss of the crop, you can lose the whole tree, which will die.

Removing affected leaves

Coping with curliness is not easy, but if you approach the fight against the fungus in a complex way, then the result is likely to be positive. Pruning and subsequent burning of affected leaves and shoots is one of the primary means to defeat peach leaf curl. Treatment in this way is usually carried out in May, at a time when the signs of the disease are most pronounced. Also, experienced gardeners practice removal in several stages for greater efficiency. For example, the first pruning can be done when flowering is over. The repeated procedure is performed until the spores of the fungal infection disperse.

How to spray for curly

One of the most effective means the fight against tree diseases still remains spraying. It is important to consider in what period the peach was infected. Leaf curl, which is controlled after flowering, requires the use of tank biopreparations. These include trichodermin, planriz and pentaphage. Also at this time, fungicides can be used and Before bud break, the same means are used, as well as milk of lime and urea. When the leaf fall has departed, it is necessary to spray the tree and soil in the zone of the stem circle - that is, where the fallen leaves lie. In this case, treatment with the listed means is possible, but without fungicides.

Processing with Bordeaux mixture

Curl protection in Lately Increasingly, 3% Bordeaux mixture is being provided. It should be noted right away that this method there is a serious minus: increased phytotoxicity, which, however, well eliminates the curl of peach leaves. The treatment is accompanied by a delay in the entry of the tree into the fruiting period and affects the low yield. In addition, treatment with such a preparation helps to increase the copper content in peach leaves. Moreover, the ratio of the presence of heavy metal will increase as the shoots grow.

Despite all the negative factors, there are obvious advantages to using Bordeaux mixture. If in the fight against other diseases its effectiveness may not justify itself against the background of negative factors, then peach leaf curl, which is treated regularly with this remedy, will definitely give a beneficial result. This option is especially useful in the fight against an infection that has developed over several years.

Clay processing

If for processing it is rather recommended as a specialized means of combating the disease, then clay is a traditional folk remedy. It is used in composition with lime and acts as an effective adhesive. But not only this property of the substance is important - clay also works as an adsorbent, not to mention the presence of a number of nutrients in the composition. Among them are silicon, aluminum, sulfur and other components that allow you to defeat the curliness of peach leaves. Treatment folk remedies in the form of clay with lime improves the biological and physico-chemical characteristics of the peach, at the same time nourishing the tree with mineral elements.

If it is not possible to use clay together with lime milk, then the option of using the first one in its pure form is not excluded. In this case, the fungicidal effect will be less pronounced, but the phytocidal properties will manifest themselves quite effectively, eliminating the peach disease. Curly leaves are most easily eliminated with a clay-lime mixture in an optimal consistency, which provides a neutral effect. To do this, the ratio of clay to milk of lime should be 4:1.

Modern remedies for curly hair

It happens that the action of the clay-lime mortar does not help, and the use of the Bordeaux mixture is excluded due to its negative factors in relation to a particular plant. So the question arises of how to treat a peach from leaf curl with minimal harm to the tree itself. The answer lies in the preparations of a new generation, among which are fast, delan and chorus. They can be used singly, in combination, or alternately. In addition, the addition of a clay-lime mortar can significantly prolong the effect of the same delan. According to experts, such drugs provide 98 percent biological effectiveness in the treatment of leaf curl.
