Monilial burn: symptoms and control measures

Monilial burn: symptoms and control measures


Monilial burn of stone fruit crops ruins the harvest

In the North-West region, probably, there is no such personal plot on which plums, ordinary cherries or felt cherries would not be grown. In addition, recently, many gardeners have been trying to plant cherries and even apricots in the garden - cultures that have been considered southern plants from time immemorial.

However, the emergence and spread of monilial burn of stone fruit crops in our regions may turn out to be a serious brake on the cultivation of all these plant species, especially cherry. Sweet cherry is less frequently affected by monilial burn, although on some trees the drying of young shoots and branches can be significant.


In the 60-70s of the last century, this disease of stone fruit crops was found mainly in the southern regions of the Soviet Union - in Moldova, Ukraine, in the south of the Krasnodar Territory. However, in the last decade, it has spread widely in the Central and Non-Chernozem parts of Russia and has already reached the northwestern regions, including the Leningrad region. In some seasons, this disease takes on an epiphytotic character.

This means that in the coming years (especially during rainy springs) it can significantly thin out (if not completely negate) orchards with stone fruit crops - plums, cherries and especially cherries, affecting flower shoots and leading to large losses. The annual infection of a tree (cherry) with this mycosis leads to its complete death.

This penetration of the disease from the south to the northern regions is apparently associated with a significant warming of the climate in recent years. I think that the haphazard importation of tree varieties completely unsuitable for our conditions played a role, and this allowed the formation of, probably, more aggressive races of the causative agent of this disease. Although, apparently, the disease itself was still present in our latitudes earlier, affecting mainly felt cherries.

Features of monilial burn

It is believed that two types of fungi are widespread on stone fruit crops (and, as it were, two forms of manifestation): Monilia cinerea Bon. - the causative agent of monilial burn - gray rot of stone fruits. It more often affects this particular group of crops, causing them to burn flowers, shoots of fruit twigs, branches, sometimes whole trees, as well as rot of fruits.

The second type is Monilia fructigena Pers. - the causative agent of fruit rot. It more often affects the fruits of pome fruits and less often of stone fruits. By the way, it is possible to cross-contaminate cherries and apples with the pathogen Monilia fructigena, but the symptoms on these plants are characterized by some deviations from the typical signs.

Infection of plants with fungal spores usually occurs through the stigma of the pistil. On contact with the stigma, as well as in the presence of moisture or juice secreted by the stigma, the spores grow into the mycelium. Its threads very quickly penetrate the fruit twig through the pistil and peduncle. In the inflorescence, the fungus affects 1-2 or all flowers at once. The affected inflorescence turns brown, withers, and then wilts. The disease manifests itself most often at the end of flowering: first the flowers turn brown, then the leaves, ovaries and fruit twigs.

Through the fruit branches, the mycelium of the fungus penetrates into the skeletal branches and causes them to dry out. If inflorescences located on perennial branches are damaged, necrotic ulcers up to 6-7 cm long may form on the latter. If the flowers were infected at a later period, the resulting cherry and sweet cherry fruits rot, shrivel and mummify.

After infection, the movement of the fungus along the branches is quite intensive. High relative humidity (70-98%) and low air temperature (average daily 7 ... 17 ° C) contribute to a rapid increase in necrotic tissue. After the mycelium stops its development, a brown transverse strip (necrosis) is formed at the site of the lesion of the branches, conventionally separating the damaged part from the healthy one.

The affected part of the shoot is always clearly distinguished by its dark brown color. The length of shriveled shoots largely depends on the variety and conditions of the year. According to the majority of specialists who have studied the nature of the drying out of the affected tissues, the primary foci of spring damage during the summer do not increase and do not become active in the spring of next year. The next infection occurs again from the flowers. As with the initial infection, the re-spread of the infection occurs with the help of spores: they are carried by the wind, raindrops and insects.

The pathogen overwinters on affected branches and fruits. Mild winters favor the preservation of the viability of the pathogen's conidia; early spring rains also contribute to this. Monilial burn of fruit crops is massive if relatively cool and humid weather is present during the flowering period of trees.


In this case, the active appearance of the fruiting of the fungus is observed on small gray tubercles, crowded in the places of attachment of last year's leaves (near the buds) and mainly at the base of last year's dead one-year growth. Experts note that on the buds and flowers, despite their massive death, the fruiting of the fungus may be absent. If, before flowering in April, dry and warm weather is observed, unfavorable for spring sporulation, then winter spores may be the only source of infection of stone fruit flowers.

Symptoms of monilial burn of fruit crops

Previously, gardeners attributed such a phenomenon, which seemingly without special reason, to natural disasters - frosts, dry winds or the proximity of groundwater and acid rain. They also sinned on the water vole, gnawing at the root system. No one thought then about the massive development of a fungal disease. However, time has shown that the nature of the drying out of the branches and the decrease in the yield of stone fruit crops is infectious.

Every gardener should try to recognize the symptoms of a developing disease in time. A characteristic symptom of such a phenomenon on trees is, first of all, last year's leaves and fruits, which have dried up last spring at the stage of their formation, which have sagged all winter on heavily affected trees. Another evidence of the disease is called the green bark of trees and shrubs - diseased shoots, branches and even fruits are readily colonized by algae.

The next sign of mycosis can be the appearance on the bark of one-year and 2-3-year-old shoots of numerous "lenticels" - containers of spores formed as a result of the mass formation of pathogen spores (in early spring and late autumn). This makes the bark on trees feel rough to the touch. On a diseased tree, a lot of dried up small shoots (their tips), completely covered with warts, are noticeable. On the border between the dried and outwardly healthy part of the shoot, a clear brown transverse strip along the ring is noted; the bark of the shoots is at first a dull gray color, then turns black.

Measures to combat monilial burn

When carrying out measures to combat moniliosis, all biological characteristics of the pathogen must be taken into account. It should be borne in mind that the main sources of infection are diseased shoots and branches, as well as mummified fruits. First of all, a double cutting of the affected shoots is advisable: at the first signs of the appearance of the disease and 30-40 days after flowering, when its development stops.

If the second pruning was not done on time, it can be done in the fall (after leaf fall). Cutting branches with dried flowers and leaves is done with the capture of 10-15 cm of healthy wood. This is due to the fact that numerous studies have shown: on those shoots where the affected part was cut out at the border of the affected and healthy tissue, there was a further appearance of necrotic tissue and the appearance of pads of conidial sporulation of the fungus.

Some experts believe that in case of severe damage to trees by a monilial burn, in addition to preventive pruning, summer rejuvenating pruning is effective. The fight against pests of fruit crops (bukarka, goose, moth, etc.), damaging young shoots, branches, flowers, fruits and spreading spores of fruit rot during the growing season, should be timely and mandatory. Infected fruits are harvested and destroyed.

Chemical measures in the fight against monilial burn are complicated by the presence of the mycelium inside the tissues of the affected plants (where it is well protected from external influences) and the time of infection (flowering period). According to a number of experts, at present, most modern fungicides (including those used in the summer against scab) have proven powerless against the causative agent of this disease.

They could not seriously reduce his activity. This is due to the fact that, having only a superficial effect, these drugs practically do not affect the mycelium of the fungus, which develops in the vessels of wood, leaves (in the veins), stalks, fruits. They can destroy the spores of the upper layer of the pad, and the spores of the lower layer remain viable. At the same time, comparatively effective drugs such as nitrafen, zineb, polycarbacin, basezol are now removed from the "List of drugs approved for use ..." due to their toxicity to humans.

On the other hand, the eradication and "blue" spraying carried out in early spring is quite effective to prevent outbreaks of moniliosis. The copper-containing fungicide Abiga-Peak also showed high efficiency in the fight against moniliosis. An equally good effect is obtained from the application of impact or speed (when used at the beginning and end of flowering). No negative effect of fungicides on bees was noted; on the contrary, these preparations to some extent relieved them of diseases. Interestingly, their treatment during the flowering period promoted good pollination and fruit setting. In such orchards, the quality of the fruits was the best, as well as their higher yield.

If all agrotechnical and chemical protection measures are carried out in a complex, then the problem of combating moniliosis can be completely solved by the gardener on his site within 3-4 years. However, this work should be done by all gardeners collectively and simultaneously in all gardening. The fight against monilial burn is especially important in those gardens in which the most susceptible varieties of Lotovaya, Lyubskaya and Vladimirskaya cherries are widespread.

Monilial burn: symptoms and methods of protection

Is the season over and the time to rest? Not certainly in that way. There is one fungal disease that continues to develop during the winter thaws. They call it moniliosis (monilial burn). We are used to the fact that it strikes the main blow during flowering. But in the fall, and in the winter, and in the spring, she can continue her dirty work. It develops in rainy, humid weather.

Of course, the optimum humidity for the development of the fungus is 90-100% and the temperature is + 15 ° C. But the process continues in colder months. In the South, moniliosis is widespread. In the Middle Lane, it often freezes out. However, sometimes together with a sick tree.

Quite recently, there were no means against him, except for Skor. Now you can find Horus, which can be sprayed with plants during flowering, and Tilt 250, which can be used to fight the fungus in the midst of an epidemic, and Raek ... In general, there is something to fight.

Now the garden needs to be treated with 3% Bordeaux mixture. It acts weaker against moniliosis, but the treatment must be carried out - there are many benefits from it. Do not get carried away with some chemical means of control ... agricultural technology is also important.

In particular, it is necessary to collect all the mummified fruits - they will be the source of monilia in the new season. Go through and cut out all infected shoots and burn them. It is not difficult to calculate them by gum, which covers diseased branches and shoots.

Whitewash the trunks and bases of the skeletal branches before the dormant period. Add 100-300 g of copper sulfate to the whitewash. It is very important not to place trees close to each other when setting up a garden.

Mechanical damage is the gateway to infection, so heal and cover up all wounds. Carry out pruning strictly before bud break, removing diseased branches. Cover the cuts with garden pitch.

Fight pests in a timely manner. Dig up the soil in the tree-trunk circles every fall. Avoid excess fertilizer. Use only sterile pruning tools. You can disinfect them with vodka. Try to plant resistant varieties.

And the last: the first spraying is carried out before flowering, the second - immediately after flowering.


Moniliosis (monilial burn) and its treatment on fruit trees

The first time I saw what Moniliosis looks like was in 2012. Here, in the Novokubansky District of the Krasnodar Territory, all the apricots, not having time to bloom, shed their flowers: they stood for several weeks with dried black tips of the branches - they looked like after a fire. The leaves on the surviving branches bloomed very slowly. Of course, there was no fruit. What is this attack? This is a fungal disease called moniliosis (monilial burn). It appears during the flowering period on stone fruit crops - apricot, peach, cherry, sweet cherry, plum, felt cherry, quince, grapes, others - at low temperatures, excessive moisture. How can this disease be prevented? Is it possible to treat moniliosis?

It looks like moniliosis on apricot, photo:

The causative agent of the disease - the mushroom Monilia (Monilia) penetrates through the pistil of the flower, affects young shoots. As a result, the flower part, leaves, young twigs dry out - a monilial burn occurs.

Flowers of fruit trees are affected by the Monilia fungus at low temperatures - from minus 1.5 ° С, and the ovary - from minus 0.6 ° С. I noticed that in the Kuban, a decrease in temperature in spring is caused by east winds. This year I managed to prevent apricot moniliosis - I treated apricot trees with Horus as soon as I saw the east wind in the weather forecast.

But whether the temperature drops or not, whether the east wind blows or not, the trees must be processed in any case. One should not hope that, they say, this year will blow. No, it won't! If at least once, at least one tree in you or your neighbor got sick with moniliosis - that's all - the spores of the Monilia fungus are already on the branches, trunks of your trees, waiting for suitable weather conditions to develop and ruin the future harvest.

When moniliosis is affected, wilted leaves appear on the tips of the branches:

Very often, novice gardeners do not pay attention to fallen flowers or ovaries, believing that this happened because the weather has deteriorated, and this, they say, is not worth fighting. Of course, changing weather, lowering temperatures are a strong factor. But every gardener should know that it is the cold air that creates comfortable conditions for the growth of the Monilia fungus, and, therefore, for the spread of moniliosis. Fallen flowers, ovaries tell you not only about the deteriorating weather conditions, but also that you have missed the right time to treat your trees from the monilia fungus.

Affected by the Monilia mushroom, cherry, photo:

The picture shows a cherry, the branches of which are affected, but the disease has not yet spread very much. If you notice this on your trees, then it is not too late to process them. Of course, you will lose part of the harvest, but you will have time to save something else.True, this will be possible only if warm dry weather has established after a cold night, there will be no more rainy cold weather. After all, Monilia is a fungus that multiplies by spores. In comfortable conditions - high humidity and low temperature - he will continue his "dirty" work, no processing in this case will help. Alas!

It was necessary to process this cherry during the budding period or, even better, before flowering. By the way, healthy (at first glance) fruits harvested from cherries such as in the picture should be quickly processed, because the fruit will already be infected, the spores of the Monilia fungus are still present on their surface. Such cherries will not be stored! Very quickly you will see that some of the fruit has rotted or started to rot. This applies not only to cherries, but to other stone fruits too. This is such an insidious thing - moniliosis!

Cherry tree one month after the onset of the disease:

So, under favorable weather conditions, the disease develops very quickly. Heavy rains during the flowering period, the jumping air temperature from minus temperatures at night to plus in the daytime create ideal conditions for the spread of the causative agent of moniliosis.

Experts advise, for prevention, to treat apricots, cherries, apple trees, and other fruit trees even before flowering with Mikosan-V, Bordeaux mixture, Horus, Skor, etc., then immediately after flowering to prevent moniliosis, and then another 1-2 times with a break of two weeks. Last 1-2 times after harvesting. Of course, if the trees are very tall and there is no way to spray every twig, then at least the trunk, skeletal branches of the tree should be treated. This will increase the tree's ability to resist moniliosis, the causative agents of fungal diseases.

If you missed the moment necessary for treating the garden against moniliosis, then immediately when wilting, cut the shoots to healthy leaves, burn them.

For most varieties, timely harvesting is very important, immediately after reaching ripeness. With an overstatement, the loss of fruits from the disease increases sharply.

Plum moniliosis, photo

And here in this picture is the moniliosis of the plum. The symptoms of the disease are visible on the fetus. Such plums will not wait to be eaten, they will disappear even on the tree. In this case, I was very late with the processing of the plum tree. Such fruits should be collected and destroyed - burned. Do not throw them into the compost pit, or bury them in the area. Get a breeding ground for disease instead of fertilizer.

Trees should be processed after all the leaves have fallen in the fall, always in the spring, without waiting for bud formation. If the tree is not treated in autumn, spring, then the spores of the monilia fungus will remain parasitic on the bark of the tree, and in conditions of high humidity, the infection of moniliosis will spread further. From such a tree, not only can you not collect fruits, but you can also lose the tree itself.

Gardeners should take into account that moniliosis develops in conditions of high humidity. Spores of the Monilia fungus are carried by the wind, raindrops, and insects. That is, if you notice signs of moniliosis on only one tree - apricot, plum or cherry, this does not mean that only this tree needs to be processed - ALL fruit trees in the garden should be processed.

At present, breeders have developed many new varieties of fruit crops, but there are no yet completely resistant to moniliosis.

Cherry varieties - Aleksa, Kazachka, Kirina, Chosen, Chudo-cherry, Nefris, Effective, Zhukovskaya, zoned for cultivation in the Kuban, moderately resistant to moniliosis.

The most resistant to the disease are zoned plum varieties - Krasotka, Podruga, Milena, Balkarskaya introduced - Stenley, Donetsk, Melitopol, Chachak late, Turchanka.

Improved Caucasian, Sasha, Yuzhnaya, Poppy, Scarlet, Volshebnitsa, Gift of Plenty, Clear Sun - cherry varieties with medium resistance to fungal diseases.

Apricot varieties entered in the State Register for the North Caucasian region, Dzhengutaevsky, Krasnoschekiy, Krasnoshekiy iz Nikoloev, Krasnoschekiy late, Kubanskiy black, Tamasha, Black velvet - of medium resistance to moniliosis.

For cultivation in the Kuban, the following pear varieties are recommended - Moldavian early, Krasnodar summer, Summer Sergeeva, Augustin, Conference - moderately resistant to moniliosis.

Conclusion: timely treatment with antifungal drugs will help prevent moniliosis on fruit trees.


How does moniliosis spread

Harmful spores also enter the tree through cracks and damage in the bark. They winter well on infected trees, in the leaves and fruits left on the branches. As soon as favorable conditions for reproduction are formed, be sure that the rot will return and infect neighboring plants. When it gets warmer and humid, the fungus will spread:

  • by air
  • with raindrops
  • with the help of parasites and other insects.

The main advice in the fight against monilial burns is strict prevention, regardless of the climate in your area. After all, any cool wind can provoke an outbreak of this disease, which will ultimately ruin the harvest of apricots and other trees. One affected tree is enough for Moniliosis to spread to the entire garden and areas nearby.

Attention! The incubation period for the development of the disease is 3-6 days.


How to treat cherry moniliosis in order to preserve the harvest and the tree?

Homeowners who have not previously encountered the problem mistakenly believe that recently faded trees have fallen into a zone of spring frost or unexpected cold rain. Some also blame themselves, mistaking the signs of illness for a burn from an improperly selected insecticide. In fact, the cause of shoot death is the action of a harmful fungus from the Monilia family.

Types of pathogen

The causative agent of moniliosis is a fungus of the genus monilia. It penetrates the bark of the tree during flowering in the spring. Symptomatic manifestations are not formed immediately, but at the end of the incubation period. On average, it lasts about 2 weeks.

There are 3 main types of pathogen:

  1. Monilia cinerea - spreads to peach, plum, apricot, cherry, that is, stone fruit moniliosis appears. Formed from decay and monilial burn of shoots. The fungus does not die even in winter, as it is located in fruits and shoots. As it gets warmer, spores form and spread into flowers.
  2. Monilia fructigena - applies to pome trees such as pear or apple. In winter, the fungus concentrates in fruits that are mummified. When the first warmth appears, spores form. The mushroom reaches its maximum multiplication peak during an increase in humidity. When the fruits appear, they become loose, lose their taste.
  3. Monilia cydonia - the parasite spreads to quince. Spores are localized in leaf stalks and fruits. They do not die even in freezing conditions. They begin to multiply actively at a temperature of 10-15 degrees.


How to deal with apple moniliosis

The basis of the fight against moniliosis and the prevention of the disease is the cultivation of relatively resistant varieties of apple trees:

  • Idared,
  • Jonathan,
  • Simirenko,
  • Florina.

Control and prevention measures

  1. To prevent the disease, in early spring, collect the affected fruits and leaves from the trees and under them and burn them.
  2. Treat the soil under the trees with 7% urea (700 g per 10 l of water) or 1% potassium chloride (100 g per 10 l of water).

Collect and destroy affected fruits in the summer period regularly as they appear.

How to treat apple trees for moniliosis

Treatments of apple trees from damage by fruit rot should be carried out systematically in early spring after waking up and in the fall before leaving for the winter. Closely monitor the condition of the trees and, if necessary, spray the apple trees before, during and after flowering. A copper-containing preparation showed high efficiency in the fight against moniliosis Abiga Peak (50 g per 10 l of water).

During the fruiting period, it is allowed to use environmentally friendly biological fungicides, growth stimulants and immunomodulators. This will increase the protective properties of the apple tree and improve the keeping quality and preservation of the fruit.

How to process in spring and autumn

  • In spring and autumn, whitewash boles and skeletal branches with lime with the addition of copper sulfate.
  • The first early spring spraying with Bordeaux mixture (300 g per 10 l of water) should be carried out before bud break at a temperature not lower than 5 ° C.

How to process before and after flowering

  1. In the phase of a rosebud, process trees 1% Bordeaux mixture (100 g per 10 l of water) or preparations Speed (2 g per 10 l of water), Horus (2 g per 10 l of water).
  2. After flowering apple tree, when the defeat of moniliosis is clearly visible, prune diseased branches, capturing 5–10 cm of healthy wood.Slices are required with oil paint on natural drying oil.
  3. Adding 10% of the preparation to the paint Pharmayod will enhance the protective effect.

In years of strong spread of fruit rot, two more additional treatments with the drug are carried out Speed at the beginning and end of flowering.

This drug is not harmful to bees.

Biologicals in the fight against apple moniliosis

From biological preparations against fruit rot, you can use:

  • environmentally friendly drug Albite (1 g per 10 l of water) - it inhibits the process of sporulation and is close to chemical fungicides in terms of effectiveness.
  • Gamair, TAB... (10 tablets per 10 liters of water), Fitosporin-M (20 ml per 10 l). Carry out the processing in the pink bud phase, at the beginning and at the end of flowering.
  • Fitolavin VRK (new biological product) with a consumption rate of 20 ml per 10 liters of water. The first treatment should be carried out on a green cone, the second - in the phase of a pink bud, the third - during flowering, the next two - along the ovaries 2 and 3 cm.

How to spray during fruiting

  1. A day before removing the fruit, before storage, you can carry out treatment with the drug Planriz (40 ml per 10 liters of water).
  2. The preparation improves keeping quality of fruits Kresacin (3 ml per 10 l of water), spraying with which is carried out 4–5 weeks after flowering.
  3. On the day of harvest or before laying apples for storage, they can be treated with a biological preparation Fitosporin-M (50 ml per 0.5 l of water).
