Brown spots on Lily What to do. What lilies are sick

Nutrient bulbs of lilies love not only rodents, but also smaller pests. In addition, juicy stalks and fleshy leaves of plants are affected by viral and fungal diseasesthat spoil appearance Colors and can even completely destroy them.

To cure Lily, first of all it is necessary to correctly determine the cause of its damage. Read this article to learn how to determine which pest settled on your beauties, as well as distinguish fungal and viral diseases.

Fungal diseases of lilies

Lily is striking fungal infections found in many floral crops. The spread of rotes contributes increased humidity, wrong care, lack of preventive measures.

Of all fungal diseases, gray rot is the most dangerous. Initially, the disease is striking the lower leaves of plants, but very quickly covers all parts of the flower.

Signs

The first signs of gray rot - brown round spots, which in the process of development are converted into a brown mucous cloth with a gray bloom. Gray rot spreads to rainy and crude weather as well as sharp drops Temperatures. The affected lilies do not die, but only slow down in growth and lose decorativeness.

Measures of struggle

It is difficult to stop the disease, since the causative agent winter in bulbs and plant residues. Therefore, before planting a bulb, it is necessary to soak in a 0.5-1% solution of volatile TMTD or at a 0.25-0.5% suction of Fundazola. In the event of the first signs of the disease, colors once every 1-1.5 weeks are treated with 1% mortar of burglar fluid, or other fungicide (foundazole, Xome, oxicha).

Fusariosis

Fusariosis - Rota, striking the Lily Bulbs Donets. The plant, normally developing in the season of vegetation, dies during the wintering. Cause of the disease - dampness organic fertilizerscontaining spore fungus.

Signs

The damage to the fungus begins with the bluing dock. In the place where scales are attached to it, lilies bulb becomes brown and falls apart. Recognize this disease on a growing flower is almost impossible, as it can normally develop due to the surgical roots, not damaged by fungus. Nevertheless, in winter, the plant is doomed to the inevitable death.

Measures of struggle

To displaced the soil with copper vigorous and formalin 2-3 weeks before landing on the bulbs. The bulbs themselves for half an hour to soak in a 0.2% solution of Fundazola. Landing once every 1-1.5 weeks spray with 0.1% solution of Fundazola or Babylisian. It is also possible to carry out treatment with 0.2% solution of topxin-M or euparene.

The phythium is a disease of lilies, which causes root rotting, as a result of which culture development is disturbed: the plant is not allowed nutrients and moisture. The affected lily loses decorativeness, weakly blooms.

Signs

The tops of the leaves are yellow, Lily dries. The roots of the bulbs are covered with brown spots.

Measures of struggle

Remove the affected parts of the plant. Before boarding the DProzinet soil with a 0.4% solution of colloidal sulfur, the bulbs for half an hour to soak in a 0.2% solution of Fundazola.

Blue mold affects the bulbs during the storage period.

Signs

White spots gifs fungus with a greenish flare on the bulbs. When digging bulbs, you can see that they are wishes, and their roots are dead.

Measures of struggle

The rejection of sick bulbs. Compliance with the rules of storage. Watching and disinfection of the repository.

Penicillosis

Penicillhes is striking all parts of lilies and provokes them to post.

Signs

Bulbs, flowers, stalks are covered with a green bloom. Sick plants lag behind in growth, form weak blooms.

Measures of struggle

Observe the storage rules. With the appearance of the first signs, hit the affected bulbs in a 0.2% solution of potassium mangartean.

Rust

This disease is transmitted through plant residues infected with mushroom spores.

Signs

The first signs of the disease are small colorless stains that are yellowing with time. On the surface of the stains appear pillows of red spores. As a result, the stalks and leaves of the lilies dry out.

Measures of struggle

Delete and burn affected leaves. Spray plants with a 0.2% zinyb solution and regularly feed the potash-phosphoric fertilizers. Re-land lilies to the area where the affected rusty bulbous, not earlier than in 3 years.

Viral diseases of lily

Viral diseases of the bulbous spread insect pests (tli and triples) or the flowering themselves through an infected garden equipment.

Cucumber and tobacco mosaic viruses

A fairly common disease of the lilies, which is transferred to the tool.

Signs

Cucumber and tobacco mosaic viruses are manifested in the form of bright strokes and ring spots on the leaves and flowers. As a result of the lesion, the stem lily is deformed, stops growing.

Measures of struggle

Regularly inspect lilies and remove suspicious leaves, destroy the instances affected by mosaic. Disinfect garden equipment. In order to combat the carrier of the disease (Wheel), spray landings with a 0.3% carbofos solution.

Virus Predold Tulips

This virus is in the cells of lilies. Most often tolerated tool from tulips.

Signs

Poppole virus violates the pigmentation of petals, as a result of which flowers appear with strokes, strokes, stains of another coloring. Sick bulbs of the next generation decrease in size, plants weaken, the grade gradually degenerates.

Measures of struggle

Spray landing with a 0.3% carbofos solution to protect them from the Tly. Regularly inspect lilies and remove suspicious leaves, destroy the instances affected by mosaic. Disinfect garden equipment.

Pinkness disease

The emergence of this disease in lilies provokes a whole complex of viruses.

Signs

For those affected by this virus, lilies are characterized by thickening and yellowing of the stem and the absence of flowers.

Measures of struggle

Spray landing with a 0.3% carbofos solution to protect them from the Tly. Regularly inspect lilies and remove suspicious leaves, destroy the instances affected by mosaic. Disinfect the garden inventory in front of any manipulations with the bulbs and the above-ground part of the plants.

Pests Lilies

There are about 15 species of pests that affect lilies. These small insects weaken plants and are carriers of viruses. We list the most dangerous of them.

Cobed tick

This pest is powered by juice of young shoots than inhibits the growth of lilies. Red eggs custom tick Can live in the soil up to 5 years.

Signs

Leaves of lilies twist, the plant itself gradually dry out. Upon closer look at the leaves, white eggs and adults of the red spider tick are noticeable.

Measures of struggle

When pest detects, spray plants soapy solution, 0.2% carbofos solution or acaricide (Apollo, actor, etc.).

Beetle-Piskun (Liliev Beetle, Soldering Bulk)

Bright red bug-piskun laying on the leaves of lilies larvae pink colourcovered with green-brown mucus that can deprive the plants of almost all leaves.

Signs

Prominated by the naked eye of the larvae and adults of the pest.

Measures of struggle

Spray plants with a 0.2% carbofos solution or other insecticide (into-Vir, Decis).

Lily fly is starting inside the unpainted bud of lily. Damage will be noticeable when the larva flies will already make "their own business" and will take it in the soil.

Signs

Anatheked pestles and anthers of stamens in flowers.

Measures of struggle

Destroy damaged buds. Plants with a 0.2% carbofos solution or other insecticide (dutes, Ke, etc.).

Medveda

The Medveda eats roots, bulbs and stems of lily.

Signs

The presence of the Medvedka on the site can be seen by holes in the soil. If you have noticed that Lilia is dying, and numerous moves come to the surface of the earth around the plant, most likely, the reason is in defeating by the bear.

Measures of struggle

Arrange traps for a bear in the ground. For example, pits with manure or shelter from slate, where the insect will drive to warm up and postpone the eggs. The bear assembled in one place will be easy to destroy. Late in the fall, it is necessary to deeply drag the land to destroy the wintering stages of the pest.

Khrushche (larva of the May beetle)

Like the Medveda, the larva Krushchka eats the underground parts of the flower, which leads to his death.

Signs

White fleshy larvae is noticeable in the ground. During the defeat, the death of the plant occurs.

Measures of struggle

Deep down the soil before landing, choose from it the larvae of the Khrushche hand.

This pest is laying eggs on the soil surface in May-June. From eggs, young individuals are hatched, which are embedded in a bulb, causing her posting.

Signs

In the late spring - the beginning of the summer around the lilies begin to circle small black flies that hang in flight and make a characteristic murmuric sound. If you notice these pests, they most likely, they have already postponed their larvae into the soil.

Measures of struggle

Spray plants with a 0.2% carbofos solution or other insecticide (into-Vir, etc.). In the fall, overheat the earth, to climb peat. Before boarding the bulbs, frozen Bazadin.

To reduce the amount of pests, landing lilies should be kept clean, maintain normal soil moisture, remove plant residues, destroy pests, spray insecticide plants.

We hope that now, if suddenly your lilies begin to "Handing", you can easily establish the reason for their unhealthy, clearly define the pest or the disease and in time to "declare war." Take care of your plants correctly, and let them do not get sick.

Exists great amount Diseases affecting lilies. Consider the main of them.

Gray rot, or Botrytis (Botrytis Elliptica), appears in spring in cool weather high humidity. Young leaves (amazed, starting from the bottom of the cut) look like boiling water. Sick buds are twisted, the stalks are rehearsed, fall. Gray rot is striking and wet leaves at the end of summer. The most resistant to the disease from and la-hybrids.

Perceived - white-color hybrids. For protection spray with burgundy liquid, copper-containing fungicides or other drugs. With rainy summer it is necessary to spray in 7-10 days on dry leaves.

Fusarious rot (Rota of the Donets, Basal rot) strikes the bulbs - starting with the Donets, appear cannons and yellow-brown spots. Then she disintegrates on the part, the roots are puments. Plants are infected through roots and places of mechanical damage.

Signs of fusariosis - Yellowing the lower leaves and gradual drying of the entire plant. For the winter or during the storage, the infected bulweic dies. Disease promotes heat, rejuvenation of the soil and the introduction of non-interrupted organic matter.

Highly affected plants dig and destroy. Effectively raven the bulbs 1-2 days before the landing of a 0.2% suspension of Topcin-M or Fundazola (Benle), 0.1% tecto emulsion for 30 minutes. Spring scatter on the surface of the soil lime-puff.

Sclerocycial Rota (Mushrooms SCLEROTIUM) - the cause of low growth of plants and small leaves With sufficient soil fertility and good nutrition. It is possible to detect it only when there is a spray on the bulbs. The bulbs of the affected plants are puments. The disease, the development of which contributes to the increased humidity and the acidity of the soil, is manifested by the foci. Weakly affected bulbs are kept in a solution of copper-containing drugs and transplanted to a new place. You can not thicken the landing.

Phythium, or root rot (mushrooms of the genus Phytium), - Plants lag behind in growth, the leaves are minced, falls out or do not form buds, the tops of the leaves are yellow. The bulb is healthy, and the roots are covered with small brown spots. The development of the disease is more often occurring during the convergence. The soil is watered with a 0.2% solution of Fundazola, 8-10 liters per 1 square meter. m. For prophylaxis Before planting the bulbs are etched by fungicides.

Appearing colorless small stains on the leaves, which increase in size, yellow and dry, caused by rust (Uromyces Lilii). Under the epidermis in these places, summer and autumn sputs of yellow-orange or dark brown color are formed, respectively. Sick leaves are collected for the fight against rust and destroy the leaves, the plants spray 2-3 times with copper-containing drugs, more often fed by phosphorus-potash fertilizers.

If the flowers, flowers and bulbs are rotated and covered with a green rode with warm and wet weather - plants are amazed by penicillosis (genuine Penicillium genus). For spraying, any fungicides containing zinc, copper or a mortar solution of raspberry color are used.

Bacterial, or wet, rot (Pectobacterium Carotovorum, Pectobacterium AROIDea) Amazes bulbs, leaves and blooms. An early spring on the leaves appear brown oval spots, gradually yellow, then drop leaves and flowers. The disease is developing due to the oveurgement of the soil and excess nitrogen. During storage on the scales, the bulbs appear unpleasant spots, causing rotting. Such bulbs are immediately separated and destroyed. When the disease appears during the growth of Lily, they are sprayed with fungicides. Before boarding the bulbs, etching the foundazole or pour them the soil in the well.

Viral diseases

Mosaic Lily (Lily Mosaic Virus) Determine the pale green spots on young leaves and strips along the residents of the sheet. Plant growth is suspended. Deformed leaves, buds and flowers. The mosaic virus is transmitted to the tool and mechanical path with the juice of patients.

For rosette Virus (Lily Rosette Virus)the bloomout is deformed and acquires the shape of the socket, as its growth is strongly delayed. Chlorotic leaves are deformed. Cucumber and tobacco mosaic viruses cause ring spots and touches on the leaves. Lilies are desirable not to disembark next to tulips and hosts to avoid infection with a virus of spells, control measures that are not yet developed. All patient plants burn. Preventive measure - the destruction of the threshing as a sick carrier. More resistant to viral diseases Orleans hybrids.

Non-infectious diseases

Chlorosis - The yellowing of the leaves between the veins is observed if the acidity of the soil is above the norm - the soil is too alkaline.

Purple dyeing of foliage associated with a disadvantage of nutrition (due to rejection of the roots). It occurs on poorly drainaged soil under excessive moisturizing.

Deformation of leaves and curvature of stems (The formation of thickens and bubbles) occurs when damaged lilies by spring frosts. The most susceptible to damage from lowering the temperature of tubular hybrids.

Faciation - The captivity of several stems into one with random damage to the point of growth. This phenomenon is observed only when good careWhen lilies are able to produce several shoots from one bulb. The next year will grow normal stem.

It happens that the bulbs planted for all rules in the first year does not germinate (fell asleep) and does not die, but the next spring gives sprout.

If brown spots appeared on the leaves of lilies, the plant suffers from gray rot. How to deal with it?

Gray rot is especially often developing in climatic zones temperate temperature and large quantity precipitation. Most often, she is sick with perennial floral cultures (lilies, peonies, tulips) in open soil. Pathogenic infection accumulates in the soil, roots, bulbs and especially on the above-ground parts of the plant with prolonged cultivation in one place. In summer and spring, the infection spreads from patients with healthy plants through water and air. Disputes during the growing season are flying out and fall on healthy plants, settle on the soil and weeds. Mitcelium and spores on plant residues in the soil and in the roast rosette of the leaves. Optimal temperature For their development - 16-21 ° C.

Measures of struggle

• Only healthy bulbs on an outdoor, well ventilated, sunny plot.
• Do not overflow by manure and nitrogen fertilizers - This reduces the resistance of plants to diseases.
• Destroy weeds and pests that weaken plants.
• The affected parts of the plants, without waiting for the end of the vegetation, cut and burn.
• In no case do not instinate them with plant residues. In the presence of infection on the plot of the bulbs before planting, drank in a solution of fungicide (Topcin-M - 0.2%; Fundazole - 0.2%; burglar liquid - 1%; Copper chloroisa - 0.5%; Bayleton - 0.1%, Azophos - 2%). You can also shed the soil around the lilies with a solution of the drug Maxim. It is effective against many fungal diseases, incl. Gray rot. Fungicide kills infection around lilies and surface bulbs.
• But since the contamination of stems, leaves and buds occurs mainly on the surface, more effectively spray the above-ground part of the plants 2-3 times (with an interval of 16-20 days) solutions of fungicides to the disease and in case of its signs (specks on the leaves).

Often gray rot is striking all the plant: leaves, buds, stalks, flowers and seed boxes, sometimes - and bulbs. First, dark brown spots appear, later the pale in the center. On the leaves they become transparent with darker water edges. The stains increase in the amount, merge, cover all the leaves and cause them to die. With damage to the bulbs, the same spots appear on the upper slices. With the defeat of the stem, the entire supervised part of the plant will rake and dry. Sick buds are not disclosed, raging. All patients of plants in wet weather Covered by the spioning of the mushroom.

Growing from what colors and plants to make bouquets in the country

What plants do not combine with others that put in the bedroom and what is on dinner table And what if the colors are completely ...

LiliesTheir grace and grace of people were appreciated in the distant times, which we call the period "BC." To this time, not having a blue painting of lily, nevertheless, die with a variety of varieties that are pleased with the widest gamut of colors. Even the flower shape began to vary - lilies are ordinary, have a chalmid form and even be terrain. However, all this beauty in one moment can spoil the disease, it arises often by overlooking the owner, sometimes due to its disadvantaged and empty relations to plants, and sometimes fatal carriers for the lilies of diseases can become a colony of aphids or a conventional garden knife, which has been cut off Sick plant.

You should not too thickening landing, lilies love the space, they will be better feeling the fed wind and warmed by the sun. If the landing is too thickened, it can lead to the appearance of gray rot. This disease is destroyed and the leaves, and stalks and buds, especially actively extending to crude weather or with excess watering. The first signs of the disease appear in the form of spots on the lower leaves, from light spots turn into brown and very quickly grow up, merging into huge covered with gray raid. Just a couple of days and your lily can perish, and the infection will penetrate into the bulb and can move with it to the next area.

From prevention measures It should be called primarily the mandatory removal of plant residues in the fall, for it is in them the disease and winter. All unfamiliar bulbs before landing onto their plot necessarily disinfect in the Fundazola solution. Change the place of landing of lilies often, this and the landscape will revitalize and relieve the accumulation of disease in the soil. Well, finally, do not pour plants, only the morning watering and pour water under the root.
In the spring, also for prophylaxis, can be treated with plants 0.5% solution copper KaperThis is safe and efficient, and in rainy weather you can cover the plants, building a suggestion from a greenhouse film.
Bulbs Lily affects another dangerous disease - fusariosis. Most often, the disease appears precisely where the bulb during the digging was damaged, therefore it may take a neat, unhurried spraying of bulbs from its occurrence. Naturally, notice the disease on initial stage It is possible only during the storage period of the bulbs, so check the repository more often, revising planting material. If you noticed yellow-brown spots on the bulbs, then it's time to beat the alarm, because in just a week the bulb can be contracted, lounging on the part.
Of the struggle measures, first of all, it is necessary to name the simple removal of beginners to rotate the flashes of the bulbs, or the treatment of more strongly damaged by the solution of Fundazola.

Leaves, stems and bulbs Lily affects and rust. The first signs of the presence of this disease are manifested in the form of small non-color specks on the leaves, which are gradually yellow and increase in size. Yellow "This is the most dangerous stage, she suggests that the spores of the fungus ripened and can move the wind over long distances, infected with healthy plants. If you do not take any actions, then the plant and still a dozen around it are simply dried.
Rust from rust lily can simple potash-phosphoric feeding. If the presence of colorless spots noticed at the very beginning of the development of the disease, then immediately remove these parts of the plants and destroy. Helps and spraying by the Bordeaux fluid, which is carried out by shooting in the spring, and with a weak lesion helps the processing of 0.5% zinab.
A rather dangerous disease is the sclerocomial rot, It is manifested in the form of uneven shoots even early in spring. The bulbs do not give shoots, because the cervix and on the bottom is formed a white felt flare - traces of the vital mushroom. If the disease develops a little later, when the bulb has already launched the roots and gave growths, they simply dismissed.
The mushroom is most actively developing into cool and wet weather, therefore, in order to maximize their lilies from such a serious illness, it is necessary to choose to land on the bulbs only well warmed, open areas With loose soil, perfectly absorbed moisture.
Unknown bulbs before planting must be moved, and the soil is displaced. Sick plants or suspicious bulbs should be immediately removed from the site and destroy. At the place of their growth, it is necessary to dig a hole, remove part of the soil and fall asleep the liberated space ash or chlorine lime.
Often the diseases of the disease are other bulbous plants, for example, tulips or hyacinths, so after them lilies are better not to plant.
Diseases affecting the roots of the bulbs include root rot. As a rule, the roots at the beginning of the development of rotes are covered with dark spots, and then begin to die, which leads to the lagging and weakening of plants and their subsequent death. Naturally, the roots are in the soil and on them it is impossible to determine the development of the disease, but it is manifested on the leaves - their tops begin to shut and soak.
In order to prevent prevention, it is possible to recommend a careful selection of planting material, regular soil disinfection with a solution of 0.4% of colloidal sulfur, as well as the removal of affected plants from the site and their destruction.
On leaf damage, still in early spring, by education on them oval brown spots It can be judged about the presence of a different dangerous disease - bacterial rot . If you do not start processing infected plants with fungicides, then after a few days they may die due to the active life of the mushroom, leading to the rotten and the dejudation of the leaves and the flowers.
They am amazed by this disease and bulbs if you take such a bulb in your hands and try to slightly squeeze your fingers, then it collapses, exposing the rotten core having an extremely unpleasant smell.
When a contaminated bulb is found, all kept with it must be revised and leaving the fungicide.
Before boarding, if there is a risk of such a disease, the soil and bulbs need to be treated with any fungicide in a weak concentration.
However, in addition to common mushroom diseasesWith which you can easily fight, observing the crop rotation, airing and drying the storage facilities, not thickening and no floodplain, as well as using only the proven seating material, there are viral diseases, with which it is extremely difficult to deal with. Invasion of tri or dirty garden tools - And your favorites will begin to wake and quickly lose most His attractiveness. Viral diseases They can show themselves suddenly, suddenly the color of the flower will change, it will become ugly, sparkle stems or leaves ...
Fight with viral diseases need drastically - the first thing to do is to dig and remove a suspicious plant from the site, because in the case further development Viruses can kill all your collection.
The viral diseases are actually quite a lot, but the most common and found on Lily are the following:
Tulip transmitted virus Pepperpoles - The first sign of its presence is the spotted coloring of flowers atypical for the grown variety. Turn the disease of the colony of Tly, it is transmitted through the cutting tool.
A whole complex of viruses causes a disease - the rosette. It manifests itself in a sharp delay in the growth of the color-point victory. Escape is becoming more flat, and the stem is deformed, at the same time he is twisted and becoming chlorotic leaves. The plant slows down and fades. The main carrier of the virus is the TLL.
Well, known to many mosaic, it often disguises it under a lighter disease - gray rot. The first signs are pale gray stripes and specks on the leaves, after which the disease seems to stop developing. Lily grows, blooms and even can exist for quite a long time, but in the end, it will still die, and the infection will spread further with the help of aphids or cutting tool.
Anti-viral diseaseAs already mentioned, it is mandatory removal from a plot of all suspicious Races. Well, the prevention is much more humane, so if you are growing lilies on the cut, then you must have two or three at hand cutting tools. Cutting one flower, just lower the tool into the disinfectant liquid (alcohol, boiling water) using other, and then repeat the procedure.

The use of clean tools in combination with the fight against tool and ants, which are its peddles, you maximize your site from the occurrence of very dangerous virus diseases.
