Stages of processing fruit trees from pests and insects

Chemical spraying is considered the most effective preventive measure, and is carried out in several stages:

• The first stage - after the snow melts, before budding (early spring spraying). Usually this is the end of March, with temperatures above 5 degrees Celsius.

During this period, tree trunks are carefully inspected for the presence of insect clutches, old and exfoliated bark is removed, after which they are treated with lime-containing agents. In early spring, the method of processing with diesel fuel is used - after spraying, it creates an oily film, under which pupae and insect eggs die within a few hours.

It is also necessary to carry out preventive treatment with insecticides (Aktara, Alatar) with the addition of fungicides (Agrolekar, Broneks, Bordeaux mixture).

• The second - from mid-April, after the opening of the first leaves (green cone phase).

Before flowering, it is necessary to complete the second stage of processing from the moth. Organophosphorus agents are used, such as: Azamtiophos, Glyphosphate. As well as biological active ingredients Bacillus subtilis: strain 26 D, M-22 VIZR, IPM 215.

• The third - after the end of flowering at the end of May.

During the flowering period from pests, processing is not performed, but it is possible to protect the color from diseases and ticks that come out of hibernation immediately after its completion. Copper sulfate and "Preparation 30 V" should be used. Biological pesticides are also suitable: Abamectin, Spinosad, Aversectin S.

• The last treatment takes place in the fall, after the leaves fall to reduce the number of pests that have settled for the winter.

During this period, spraying with substances of general action from pests and diseases is carried out so that they do not have time to hide for the winter. Use Karambid, Vitriol and Fufafon.

For old, but still fruiting plants, additional strengthening dressing is carried out in July, for better formation and further ripening of fruits.

The most effective preparations for treating the garden

• Fufafon - protects trees from apple, plum sawfly, cherry weevil, kidney mite;
• Carbamide (urea) - from aphids, honeydew, caterpillars, apple blossom beetle, leafworm caterpillars. 50 gr. urea is diluted in 10 liters of water and sprayed into the garden after flowering. After getting into the soil, urea additionally fertilizes it;
• Copper sulfate (copper sulfate) protects against curliness, coccomycosis, moniliosis, black cancer, scab, phylosticosis, fruit rot. 100 g vitriol is diluted in 10 liters of water. Consumption from 2 to 5 liters. solution per tree, depending on size, per bush - up to 1.5 liters. Prophylactically disinfect plant roots from bacterial and fungal infections, lowering them in a ready-made 3% solution for 3 minutes. Copper sulfate is a toxic substance, it is strictly forbidden to pour the remains into water bodies;

• Iron vitriol destroys moss, lichen, septosporosis, cytosporosis, powdery mildew, gray rot... Additionally, it compensates for the lack of iron in fruit trees. Due to the high acidity, ferrous sulfate can burn the leaves, so a 3% solution is used before blooming, and in the fall after the foliage has fallen off. The rest of the time, 1% will do;
• "Preparation 30 V" - eliminates scale insects, aphids, moths, whiteflies, red and brown fruit mites. The drug creates a film on the bark and disrupts the metabolism in eggs and insect larvae, leading to their death. 200 gr. diluted in 10 liters of water and sprayed before bud break and after foliage has fallen, taking a break once every 2 years;
• Bordeaux mixture protects against curliness, monoliosis and scab. 150 g copper sulfate bred in warm water, 200 gr. lime is quenched in a metal dish. Then, a solution of copper sulfate, stirring, is poured into the lime solution.

To make the garden meet your expectations, please the eye and soul good harvest, it is necessary to provide him with proper, professional care. Landscaping workshop Le Nôtre Park will be happy to take care of the processing and spraying of fruit trees and shrubs. For this we have experienced specialists, special equipment. It is easy to order garden processing in Moscow and the Moscow region - just one call to the phone number indicated in the right column.

Cost of work:

Spring processing fruit trees - a number of measures aimed at the prevention and treatment of diseases of trees and shrubs, to prevent the invasion of insect pests or to destroy them. The qualitative and quantitative indicators of the future harvest depend on how timely, promptly, organized and competently the work is carried out.

Spring processing of trees is carried out in several stages:

• Before the start of the growing season
• On the green cone when the buds hatch
• During flowering
• After flowering.

Spraying is also carried out outside this schedule, as needed.

But at the same time, one must be aware that spring spraying of fruit trees is not a strictly regulated event in the sense that no one will say in advance exactly when and with what preparations to treat the garden, because each tree is unique in its characteristics and condition, respectively, requires individual approach... When planning the processing of fruit trees in the spring, it is necessary to start, first of all, from the degree of infection of the garden with certain insects and diseases. The “just in case” principle does not apply to trees. Excessive use of chemicals can adversely affect the well-being of plants, moreover, it is undesirable for humans and the environment generally.

Landscape workshop LE-PARK provides services for complex spring processing of trees and shrubs in Moscow and the Moscow region. Our specialists carry out competent planning of events, correct selection preparations, timely and high-quality spraying. You can order both complex garden care and seasonal garden treatment.

First treatment before kidney awakening

In early March, when the snow has just melted, and the daytime temperature is stable within + 5 ° C, you can start preventive or health-improving measures.

Pruning and cleaning trees and shrubs

Garden processing in early spring starts with pruning trees and shrubs. It is necessary to remove tops, dead and frozen branches, to clear the thickened crown. At the same time, it is necessary to treat the areas of the bark damaged by rodents. The sites of damage are cleaned to a living woody tissue, they must be treated first with copper sulfate (1% solution), then with a runnet (in the same way, the points of cut branches are processed when pruning, copper sulfate is not required).

After that, it is necessary to carefully, without damaging the bark, to clean the trunks and branches from exfoliated and cracked dead bark, from fungal deposits, lichens. The removed dead bark cannot be left under the tree. It is advisable to pre-lay a cellophane film or other bedding around the trunk and under the crown. Collect and incinerate the garbage after completion of the work. If there are stumps in the garden that are a constant source of fungal diseases, they must be uprooted.

It is imperative to process the hollows, if any. Clean them, disinfect, lubricate and leave to dry, covering from rain and dirt.

Barrel processing

Further, in the spring processing of trees, whitewashing of trunks and tree branches follows. The task of this event is to prevent the development of the remaining larvae laid by pests in the fall, to scare off adults of insect pests, which will soon wake up and kill fungal spores.

Effective for these purposes are modern facilities(ready-to-use), which can be purchased from specialized stores. They are of several types: aerosol, water-dispersion, acrylic. They usually contain fungicides. It is desirable that the mixture is breathable, which is especially important for young trees.

You can prepare a solution for whitewashing trees yourself. To do this, dilute 2 kilograms of slaked lime in a bucket of water, add 1 kg of clay and 250 g of copper sulfate. Some add laundry soap, glue. Mix everything well. With this mixture, whitewash the trunks and the lower parts of the trunk branches of trees.

It is also necessary to prepare near-barrel platforms for processing. If autumn works were not carried out, this must be given the utmost attention. Last year's foliage, mummified fruits, remove and burn.

First spraying of trees and shrubs in early spring

The very first spring spraying of trees is mandatory. Spraying is carried out before the awakening of the buds, and it is directed, first of all, against fungal diseases - scab, coccomycosis, leaf spot, against mosses and lichens, etc., as well as against aphids, ticks, apple moth caterpillars, copperheads, etc.

How to spray trees in early spring? There are many drugs on sale now. The problem is that they are often narrowly targeted. Therefore, pay attention to the description when buying. Better to use drugs wide range actions. It is clear that it is difficult for a person far from gardening, and sometimes even impossible, to quickly understand the intricacies of this matter. The right decision will seek help from professionals who know exactly what, when, how much and how.

But, if this is not possible, for one reason or another, then we advise you to use proven and reliable means. These are copper sulfate, Bordeaux liquid, urea, iron sulfate. Pay attention to the mixtures of carbamide with copper sulfate. They are good because, in addition to their direct function of plant protection, they play the role of nitrogen fertilizer and delay the growing season for a week and a half. Both additional factors are helpful. Nitrogen fertilizing quite appropriate at the start, and late flowering reduces the risk of falling into spring frosts.

It is necessary to spray trees abundantly, starting from the surface of the crown and gradually moving inward, towards the trunk in the direction from top to bottom. The near-wellbore areas must also be thoroughly treated with a solution, after which the area must be closed. near-trunk circles black film (the film is removed after the end of flowering). This is done in order to reduce the likelihood of the larvae of harmful insects leaving the soil.

After spraying, trapping belts can be put on the trees. And although the insects have not yet awakened, very soon their hordes will rush into the trees.

As for shrubs - currants and gooseberries, they are processed immediately after the snow melts. On the gooseberry, it is necessary to cut out branches damaged by American powdery mildew; on the currants, cut out branches with unnaturally swollen buds, in which the females of the currant bud mite have settled (remove the cut branches outside the garden and burn). Shrubs are sprayed with solutions ferrous sulfate or nitraphene.

Second spring treatment on a green cone

By the time the buds hatch, the life of flora and fauna will resume completely after winter and it will become a little clearer what troubles threaten the garden. In addition, an attentive gardener can already, in some approximation, predict outbreaks of diseases and the activity of certain types of pests (taking into account current and last year's observations).

The selection of drugs for the treatment of trees and shrubs at this spring time is not an easy task. Every year, dozens of new products are released, to which the pests adapt throughout the year. No matter how good this or that drug is, it is not able to solve all problems in a comprehensive manner, in one go. Therefore, it is necessary to carefully and accurately diagnose diseases, determine the type of pests and select the appropriate means of protecting and treating trees.

If you live in Moscow or the Moscow region, qualified gardeners of the Lenotre Park landscape workshop are at your service. You can get professional advice at any time or use the services of specialists for spring spraying of fruit trees and shrubs.

Preparations, depending on the condition of the trees, can be used chemical or biological.

Chemicals are quite radical agents with some undesirable side effects on the environment.

Biological products are harmless to the environment, animals, pollinating insects and humans. Their production is based on the use of live microorganisms (bacteria, bacterial viruses, antagonist fungi). They are not so aggressive towards pests and to achieve a result, they are sprayed more often.

Chemicals:

• Bordeaux liquid- broad spectrum fungicide
• Fufanon- a broad-spectrum insecticide against ticks, weevils, leafworms, scale insects, raspberry beetles, aphids, thrips, moths, moths, etc.
• Decis- insecticide of contact-intestinal action against Homoptera, Lepidoptera, Coleoptera
• Inta-Vir- enteric contact insecticide to combat aphids, leaf-eating caterpillars, thrips, whitefly
• Akarin- a broad-spectrum insecticide for the destruction of ticks, aphids, sawflies, moths, leafworms, garden pests.
• Bi-58- insectoaccaricide is effective against ticks, scale insects, leafworms, moths, sucker, moths, root pests.

Biologicals:

• Lepidocide- for processing from caterpillars, false caterpillars, sawflies on fruit and berry and forest deciduous, coniferous species.
• Bitoxibacillin (BTB-202) completely repeats the action of the previous drug, and is also used against spider mites.
• Gaupsin- used against all fungal diseases, as well as against ticks, moths, leafworms, aphids.
• Fitoverm- recommended for the fight against ticks, moths, many species of aphids, apple moth, sawflies, thrips, leaf rollers.

Spraying trees during flowering

During flowering, the garden is not treated with insecticides and fungicides. You can use biological products that stimulate the formation of the ovary. This is especially true when, during the flowering period of trees, the weather is not conducive to the flight of bees. Actually, the drug is called "Ovary" or "Universal Ovary". It is classified as a growth promoter.

Fruit trees are processed two times - during the period of active flowering, and during the period of fruit formation (7-10 days after the first spraying).

Berry bushes are also sprayed twice - in the budding phase, and during the formation of the ovary.

During flowering, the intensity of gardening is reduced. You can take the time to fill the hollows that have been cleaned and disinfected earlier.

Spraying trees and shrubs after flowering

By the time of the beginning of fruiting, all insects have already woken up and are aimed at creating voracious offspring, which will destroy the entire future harvest along with the foliage - a trifle. Therefore, one must not lose vigilance. At this time, they process fruit trees from pests, guided by the principle of an individual approach.

For apricot, the main threat is clasterosporium and monilial burn. Regardless of previous treatments, apricot trees need to be treated with copper oxychloride or 1% copper sulfate solution. If aphids and leaf rollers are present, add insecticide to the spray solution.

Plum most often suffers from moniliosis, clasterosporiosis, polystygmosis, etc. Copper oxychloride with the addition of an insecticide (if necessary) is used for spraying.

Sweet cherries and cherries are susceptible to clasterosporia, coccomycosis, aphids appear on the foliage, leaf rollers, cherry fly, etc. are activated. For fungal diseases, trees are treated with topsin, copper oxychloride. From insects - spraying with ash, sumition.

On pears and apple trees, after flowering, the appearance of powdery mildew, scab and other spots on foliage. It is necessary to spray with fungicides such as Vectra, Rubigan, strobe, speed. Repeat spraying after 12 days, while changing the drug to another.

And in this way it is necessary to analyze and spray all the fruit trees and shrubs in the garden.

After the trees have faded, there is a high risk of sawflies, ticks, aphids, leafworms and other pests. At the first signs of the presence of these "friends" of the garden, it is necessary to treat the trees with broad-spectrum insecticides - BI 58N, Rogor S, Mitak, Danadim, etc.

For the successful prosperity and fruiting of the garden, it is required to provide proper care behind every plant. One of critical milestones worries is processing trees in the spring. During this time of year, several sprays and whitewash should be carried out to protect the garden from pests and diseases. In this article, we will take a closer look at all stages of processing, preparations and technology, and also give a spray schedule.

If you do not want to bother too much: spend time and effort caring for plants, use the services of professional gardeners. We offer following services: spraying fruit bearers, processing conifers spring, pruning, fertilizing and other activities to ensure ideal conditions for the habitation of every bush and tree! :)

As soon as the snow melted

The first processing of trees in the spring is carried out even before bud break. With the onset of warm days, gardeners begin cleaning the territory, removing insulation from the boles, and pruning. At the same time, the first work was carried out to protect plants from all kinds of pests.

An obligatory step is lime treatment of trees in spring... This procedure will protect the stems from sunburn on hot days, and will also serve as a prophylaxis against insects. The fact is that many insects hibernate in the pores of the bark. Before whitewashing, the trunks are cleaned, therefore, they destroy the wintering places of insects. After cleaning, the bark is thoroughly covered lime mortar, which in turn burns out the eggs and pupae. After carrying out this procedure, the chances of survival for the insects that overwintered in the trunk are zero.

It is considered effective processing of trees in early spring with diesel fuel. The plantings are evenly sprayed with this substance. Diesel fuel forms an oily film on the surface of plants, thereby blocking access to oxygen for insects. Most of eggs and pupae die out within hours after spraying.

Before bud break

The next step in caring for the garden is the processing of fruit trees in the spring before bud break. The procedure is carried out with the aim of combating the emerging insect larvae. Also, the event is carried out to destroy the causative agents of various diseases.

During this time, experienced gardeners are struggling with the following diseases:

• on pome crops - scab, cytosporosis, anthracnose, black cancer;
• on stone fruits - moniliosis, cytosporosis, clasterosporium, clasterosporium, coccomycosis.

Before and during bud break, trees are treated in spring from pests with the help of special insecticides. For effectiveness, they are added to fungicides and the resulting mixture is sprayed, which provides simultaneous protection from insects and all kinds of diseases.

Trees processing in spring video

Treatment of the garden from diseases and pests in the spring includes the elimination of insects and their larvae, the prevention of diseases, strengthening the resistance of shrubs, trees and other plants to weather conditions, as well as providing protection from the influence external environment... Study the technologies, terms and stages of all the listed works, learn how to properly prepare the site for the summer cottage in order to collect a rich harvest in the fall.

What is spring garden processing for?

The question "Why carry out the treatment in early spring, if all these insects and sores are not even visible?" probably only interested in beginners in the gardening business, while everyone experienced gardener understands the need for these procedures. Here are some reasons why you should still pay attention to the processing of the site in the spring:

firstly, the prevention of the appearance of diseases (even if they did not exist in the previous season) will never harm. It is better to prevent a plant disease than to cure it later in all possible ways;

secondly, even if a high-quality treatment was carried out against pests and diseases in the fall, there is no guarantee that some of these comrades were not destroyed and did not survive the winter safely;

thirdly, even if no traces of pests are still visible, this does not mean that they are not there. They just haven't crawled out of their hiding places yet. And when they appear and are visually visible, then it will begin real war for the harvest.

Therefore, based on such simple things, one can understand why gardeners spend so much energy in the spring on preparing their site for summer season, spraying, lubricating, processing plantings.

Terms of spring garden processing

Then spray with drugs that protect against diseases such as:

• moniliosis;
• scab;
• klyasteriosporiosis;
• coccomycosis.

How to treat a garden in spring before and during flowering

Before the buds on trees and shrubs begin to bloom, they must be processed in order to protect them from the attack of the apple moth, caterpillars, and other insects, to prevent the development of spotting and scab. To do this, you can use "Karbofos" (10% preparation in the calculation of 70 g / 10 l of water at room temperature).

It is better not to take any action in the garden during the flowering period. But when it is over, the treatment must be carried out for prophylaxis, in order to increase the resistance of the plantings to diseases. This must be done in advance, since the period of blooming of the buds coincides in time with the release of the ticks from wintering.

Trees and shrubs need to be treated with colloidal sulfur: dissolve 80 grams of 70% paste in 10 liters of soapy water. If this moment is missed and the protection is not carried out in time, the mites will significantly harm the plantings on the site.

Folk remedies for pest and disease control in the garden in early spring

Those who often travel to the country in the spring can use a simple but effective method of fighting many pests in cloudy weather - three times, with an interval of 3-4 days, shaking off the pests on the litter if the air temperature is above 10 degrees. From pests that live in the soil (sawflies, moths, glass moths, beetle larvae), it is recommended to cover the soil under trees and shrubs with tar, film, ribbed. Sprinkle their edges with earth. Pests will not be able to get out from under cover and will die. Shelters are removed at the beginning of flowering, since useful insects emerge from the soil at this time.

Spraying with infusions and decoctions of tobacco dust, citrus peels, onion peel or dry tansy, marigold seeds, garlic, pine needles.

• Tobacco dust. To prepare a solution, 400 g of tobacco dust is infused in 10 liters of water for a day, then boiled for half an hour, then cooled and filtered. For spraying, for every 10 liters of water, you need to take 100 g of the solution, adding 40 g of soap to it for better adhesion.
• Onion peel. Pour half a bucket of onion husks into a bucket hot water, cover, leave for two days, strain and spray.

• Dry tansy. 1 kg of dried tansy collected during flowering pour 10 liters of water and boil over low heat for 15 minutes, cool, drain. For spraying, for every 10 liters of water, take 100 g of solution, add 40 g of soap and spray.
• Infusion of garlic. Chop 100 g of garlic, pour 10 liters of water for a day, strain and spray.
• Citrus peel infusion. Soak 1 kg of citrus peels, mince, pour 3 liters of water, close tightly and leave for 5 days in the dark, strain, squeeze, bottle, cork. Consume as needed, 100 g of solution per 10 liters of water.

Biologicals for pest and disease control in the garden in early spring

There are more than just home remedies for treating plants. Manufacturers produce so-called biological products:

• Fitosporin;
• Fitoferm;
• Barrier;
• Baktofit;
• Akarin;
• Batsikol;
• Bitoxibacillin and others.

Garden pest and disease control chemicals in early spring

Chemicals Treating the garden with chemicals (pesticides) is considered the most effective way protecting trees and shrubs from diseases and pests.

Modern pesticides act very quickly and retain their effect for a long time, but, unlike biological products, they can be addictive to pests. As mentioned above, the treatment of plants in early spring does not pose a danger to human health or domestic animals, since after a certain time after application, most pesticides are completely decomposed. Another advantage of chemicals is that they dissolve well in water and are generally sold in easy-to-use packages. At the same time, unlike biological products, correct dosage pesticides play a decisive role: exceeding the recommended dose can lead to plant damage (burns, reduced pollen viability, destruction of pistils) and harm to the environment, while "shortage" provokes the development of immunity in harmful organisms to the corresponding poison.

It is necessary to work with chemicals only in compliance with the safety rules as much as possible, since the toxin can harm humans and pets not only being swallowed, but also through the skin and respiratory tract.

Any summer resident wants to always see his garden as the most beautiful and healthy. There are many ways to do this, but the most basic is spring spraying. Understand how to protect trees from pests and help them thrive in the new summer cottage season.

When to spray trees in spring

The most important question in spraying fruit trees in the spring is the right time for this. The first stages of preparation for the summer season begin in March, however, fruit processing should be started only when the average daily temperature stabilizes at around +5 degrees. Often such forecasts occur in the second half of March, so it is better to take your time and wait for suitable / weather conditions so as not to harm your garden.

Spring treatment of the garden from pests and diseases includes inspecting trees for the presence deep cracks, in which pests could start. It is advisable to brush over the entire trunk to clean it of old bark, remove dried-up branches, in general, bring the tree into a well-groomed look. It is necessary to prepare the spray solution only on the day of the procedure, otherwise there will be no benefit from your labor.

Frequent question: can trees be sprayed during flowering? The answer is unequivocal - no, otherwise you can destroy all the flowers. In general, there are several types of spraying in the spring:

1. March- is aimed at protecting plums, pears, apple trees from harmful microorganisms formed during the winter. It is produced exclusively at an average daily temperature of +5 degrees.
2. April- protects the buds of fruit trees from spring frosts, prolonging the hibernation stage of the tree. Blooming occurs a little later, but this does not in any way affect the further fertility of the plant.
3. Mayskoe- after flowering, it is necessary to protect against pests and diseases. So you will protect the garden from a variety of bacteria, which during the summer can spoil not only appearance bark, but also the fertility of the tree.

How to treat the garden in the spring from diseases and pests

There are several preparations for spraying fruit trees in spring. Each is aimed at combating certain harmful factors. Knowing their action and methods of processing, you can determine when or which drug should be used in this moment... Remember that they are all potent poisonous substances, so it is very important to take care of your own and others' safety.

Preparations for the treatment of fertile trees are subdivided into biological, chemical or combined agents. Each has advantages and disadvantages. So, poisonous chemical solutions last only a few weeks, and then completely lose their properties. Biological agents are not as dangerous to humans or animals, but they must also be handled carefully. Their disadvantage is that they act only on a number of certain diseases and bacteria of fruit and shrubs, while chemicals literally kill all pests.

If you do not know how to spray trees in the spring before bud break, then the most popular spraying agents among summer residents are still combined preparations, which are very effective, do not require a large number spraying during the whole summer season... To understand which remedy is best suited only for you, you need to know the action of each, and only then choose perfect option for yourself and your garden.

Nitrofen for garden spraying

Nitrofen is a very powerful remedy. Substances destroy larvae or laid eggs of pests within winter period... With this tool, you need to process trees that are in the wintering stage, that is, just in mid-March. You can not use Nitrofen on trees that have already awakened, which are beginning to dissolve foliage. The poisonous substance can burn buds and foliage, which leads to the death of the tree.

The processing of fruit trees in spring with Nitrofen is very effective in the fight against moss, lichen, gets rid of spots, aphids, various caterpillars, ticks and leaf rollers. It is necessary to use the product exactly following the instructions. Do not forget about your own protection: gloves, clothing, and waterproof shoes. Try to keep children and animals away from the tree processing area.

Processing trees in spring with copper sulfate

Another remedy suitable for protecting trees in early spring is copper sulfate. This solution will be especially useful for fruit-bearing trees if cracks or wounds have formed on them, which require mandatory care in the form of disinfection. You can also use vitriol at the close of the season - in October after the entire harvest has been collected.

An important point in the use of this tool is the temperature at which processing is possible: from +5 to +30 degrees. You can not process fruit trees on which buds have appeared, and even more so leaves have blossomed. Better conditions- a calm day. This will protect other plants from getting into chemical on the leaves (if they have already appeared) will not harm you or the animals. Spray copper sulfate like any other protective agent for fruit and shrubs, it is necessary away from water bodies with drinking water.

Processing trees with iron sulfate in spring

Iron vitriol makes up for the lack of iron sulfate in shrubs: currants, raspberries, roses or some vegetable crops... It is necessary to spray fruit trees in the spring before the growing season, otherwise you will greatly harm the leaves, and subsequently the fruits (or rose flowers). Very important information: the dosage of ferrous sulfate is 50 g per 10 liters of water. For some reason, the manufacturers of the product rarely indicate this information on the packaging, so summer residents often look for help in various sources, which are not always reliable.

Spraying with urea

An excellent protector against pests, scab, fungal diseases is carbamide, or in another way urea. In addition, this product is a nitrogen fertilizer for the land. Processing apple trees in spring with urea prolongs the tree's hibernation, so the appearance of flowers and buds occurs much later. This protects them from death during spring frosts, which appear suddenly and rarely any of the summer residents can guess in advance when this will happen.

Like other early spring sprayers, urea is used at temperatures no lower than +5. It should stabilize, that is, day and night on the thermometer must be no less than this indicator. Spraying fruit trees in spring with carbamide protects them from pests that have laid their larvae in winter: honeydew, aphids, weevils. To dilute the drug, you will need:

• urea - 700 g;
• copper sulfate - 50 g;
• water - 10 liters.
