Protecting cherries from pests - when and with what to spray the cherry orchard? Fighting cherry weevil Cherry weevil biological control method

Spreading cherry weevil (elephant weevil) is quite extensive and coincides with the distribution of forage plants: various types of cherries, sweet cherries, plums, apricots, hawthorns and cherry plums. It covers central and southern Europe, Western and Eastern Mediterranean, Central Asia. When massively propagated, it can destroy most of the cherry harvest.

Cherry weevil beetle golden-raspberry color, with a green metallic tint, 7-9 mm long. The head in the front is elongated into a tube. The larva is legless, curved, dirty white in color, with a small brown head, up to 8 mm long.

Overwinter cherry weevil beetles in the upper layers of the soil. Early in the spring they leave their wintering grounds and first feed on buds and buds, sometimes leaves, then unripe cherry fruits. They gnaw out quite large holes on the ovary. 2-2.5 weeks after cherry blossoms, females begin oviposition, gnawing deep holes in the pulp of the fruit and placing the egg near the seed.

After about a week, a larva hatches from the egg, which penetrates the still unhard bone and eats away the core. The period of larval development lasts up to a month. Having finished feeding, they emerge from the fruit and go into the soil to a depth of 5-10 cm. Here the larvae make cradles and at the end of summer - beginning of autumn they turn into pupae. In the fall, beetles emerge from the pupae and remain in the soil until the spring of next year.

Cherry weevil elephant control measures

  1. Digging the soil in the garden early in spring or autumn destroys a significant part of the overwintering pest.
  2. How mechanical method In the fight, shaking off the beetles gives good results. It is carried out in the spring, early in the morning, while the beetles are inactive, since as the temperature rises, most of them fly away. To collect beetles, bedding made of synthetic film, tarpaulin or other material is laid under trees.

    To avoid damaging the tree bark, the ends of the poles are covered with burlap. The collected beetles are placed in a bucket with a solution of table salt or saltpeter, or a little kerosene is added to the water. Shaking off begins at the beginning of bud break and is carried out 4-5 times with an interval of 5-6 days.

  3. Spraying trees after flowering with chlorophos (15-20 g of 80% emulsion concentrate per 10 liters of water), karbofos (75 g of 10% emulsion concentrate or wettable powder per 10 liters of water), trichlorometaphos-3 (50-100 g 10% - of emulsion concentrate per 10 liters of water). If necessary (large numbers of weevils), the treatment is repeated after 7-10 days.
  4. Instead of insecticides, you can use decoctions and infusions of tobacco, aconite, larkspur or yarrow. Spraying is carried out during bud break, before flowering and after flowering. It is also important to collect damaged carrion and remove it from the garden.

Cherry weevil damages cherries, sweet cherries, and, less commonly, plums and cherry plums. The cherry weevil is very cautious and will fly away or fall to the ground in the grass when it senses a person approaching. Therefore, seeing a beetle crawling on the leaves of cherry trees is very rare in our gardens.

Beetles and larvae overwinter in the soil at a depth of 10-12 cm. In early spring (from early May to mid-June) they come to the surface and begin to colonize cherries, but appear en masse only during flowering. The beetles additionally feed on buds, flowers, ovaries and young leaves. The spongy holes in the ovaries are eaten away, and sometimes they are even eaten completely. 10-12 days after flowering, the beetles mate and begin laying eggs. The female gnaws a passage in the pulp of the fruit right up to the seed in order to lay one oval white egg in the still soft shell (mid-June).

After 7-10 days, the hatched larvae gnaw a hole in the not yet hardened bone. Having penetrated inside, they feed on its core for about a month.

By the time the cherries ripen, the yellowish-white arched larvae finish feeding.

Having left the fruit, they fall to the ground and burrow into the soil, where they pupate and after 12-15 days turn into beetles, which remain in the soil until spring. Some of the larvae enter diapause and remain in the soil until the fall of next year.

Protection against cherry weevil

  1. In the spring, from the moment the buds open until the ovary begins to form, it is advisable to shake off the beetles on the litter every morning when the air temperature is below 10°C and destroy them.
  2. In the fall, clear the trunks and branches of old dead and flaking bark, whiten the trunks special paint , and collect the cleaning and burn it;
  3. During the ripening of cherry fruits, collect carrion every day to prevent the larvae from going into the soil.
  • If beetles appear en masse after flowering, treat again a week later. fitoverm .
  • Before collecting damaged cherries, be sure to place cloth or paper on the bottom of the container you are using and leave the cherries until the next day. In a day, weevil larvae will accumulate at the bottom of the container, which will need to be collected and destroyed.

Rhubarb can not be found on everyone garden plot. It's a pity. This plant is a storehouse of vitamins and can be widely used in cooking. What is not prepared from rhubarb: soups and cabbage soup, salads, delicious jam, kvass, compotes and juices, candied fruits and marmalade, and even wine. But that's not all! A large green or red rosette of plant leaves, reminiscent of burdock, protrudes beautiful background for annuals. It is not surprising that rhubarb can also be seen in flower beds.

3 delicious sandwiches - cucumber sandwich, chicken sandwich, cabbage and meat sandwich - a great idea for quick snack or for a picnic in nature. Only fresh vegetables, juicy chicken and cream cheese and a little seasoning. There are no onions in these sandwiches; if you wish, you can add onions marinated in balsamic vinegar to any of the sandwiches; this will not spoil the taste. Having quickly prepared snacks, all that remains is to pack a picnic basket and head to the nearest green lawn.

Depending on the varietal group, the age of seedlings suitable for planting in open ground, is: for early tomatoes - 45-50 days, average ripening periods - 55-60 and late dates- at least 70 days. When planting tomato seedlings at a younger age, the period of its adaptation to new conditions is significantly extended. But success in obtaining a high-quality tomato harvest also depends on carefully following the basic rules for planting seedlings in open ground.

Unpretentious “background” plants of sansevieria do not seem boring to those who value minimalism. They are better suited than other indoor decorative foliage stars for collections that require minimal care. Stable decorativeness and extreme hardiness in only one species of sansevieria are also combined with compactness and very rapid growth - rosette sansevieria Hana. The squat rosettes of their tough leaves create striking clusters and patterns.

One of the brightest months of the garden calendar pleasantly surprises with the balanced distribution of favorable and unfavorable days for working with plants according to the lunar calendar. Vegetable gardening in June can be done throughout the entire month, while the unfavorable periods are very short and still allow you to do it useful work.

Meat with mushrooms in a frying pan is an inexpensive hot dish that is suitable for a regular lunch and for a holiday menu. Pork will cook quickly, veal and chicken too, so this is the preferred meat for the recipe. Mushrooms - fresh champignons, in my opinion, are the most good choice for homemade stew. Forest gold - boletus, boletus and other delicacies are best prepared for the winter. Boiled rice or mashed potatoes are ideal as a side dish.

I love ornamental shrubs, especially unpretentious and with interesting, non-trivial coloring of foliage. I have various Japanese spirea, Thunberg barberries, black elderberry... And there is one special shrub, which I will tell you about in this article - viburnum leaf. To realize my dream of a garden that does not require great care, he probably fits perfectly. At the same time, it is capable of greatly diversifying the picture in the garden, from spring to autumn.

But the main enemies of gardeners and garden bed dwellers - pests and weeds - also use every opportunity this month to spread. Work on crops this month is waning, and planting seedlings is reaching its peak. The lunar calendar in June is balanced for vegetables.

Many dacha owners, when arranging their territory, think about creating a lawn. The imagination, as a rule, draws magical pictures - a smooth carpet of green grass, a hammock, a sun lounger, a barbecue and beautiful trees and shrubs around the perimeter... But when faced with laying out a lawn in practice, many are surprised to learn that creating a beautiful, smooth lawn is not so easy .

Trifle with strawberries is a light dessert common in England, the USA and Scotland. I think this dish is prepared everywhere, just called differently. Trifle consists of 3 - 4 layers: fresh fruit or fruit jelly, biscuit cookies or sponge cake, whipped cream. Usually cooked custard for a layer, but for a light dessert they prefer to do without it, whipped cream is enough. This dessert is prepared in a deep transparent salad bowl so that the layers are visible.

Weeds are bad. They prevent you from growing cultivated plants. Some wild herbs and shrubs are poisonous or can cause allergies. At the same time, many weeds can bring great benefits. They are used and how medicinal herbs, and as an excellent mulch or component green fertilizer, and as a means of repelling harmful insects and rodents. But in order to properly fight or use this or that plant for good, it needs to be identified.

Cherry fruits are an excellent delicacy, loved not only by children, but also by many adults. Unfortunately, various insect pests are also not averse to tasting not only cherry berries, but also the tree that produces their harvest. Moreover, pests not only eat the cherry crop, but also destroy the cherry tree itself. To prevent this nuisance, you should know what cherry pests there are, as well as methods to combat them using both folk remedies and chemicals. This will be discussed further (photo materials are attached).

The most common cherry pests and means to combat them

  • Leaf aphid. This small pest is a larva with a black or green color. Most often it affects young shoots and foliage, which are deprived of vital juices. And the leaves stop growing, wither, lose moisture and curl up. An excellent means of pest control is a drug called “Fitoverm”: it is enough to treat the tree with a solution of this drug, prepared at the rate of 2 ml of the chemical per 1 liter of water.

Advice. Keep in mind that it is possible to treat a tree with the above-mentioned preparations only if at least 10% of all foliage is affected by the pest.

  • Hawthorn butterfly. Outwardly, this pest is very similar to ordinary cabbage. It damages leaves and young cherry buds; as a result, the branches of the tree become completely deprived of their cover. Even in winter period the butterfly does not leave the “feeding” place - it remains to winter right on the tree in the nest. Treatment of the tree with the drug is carried out before the buds open, both chemical (Aktellik, etc.) and biological preparations in the spring and at the end of summer.

Slimy sawfly

  • Plum moth. Another butterfly, only this one has a light brown color. Causes irreparable damage to the crop because it lays eggs in it. As a result, caterpillars emerge from the laid eggs and eat the fruits and, as a result, the crop is almost completely destroyed. Control method: carbon or benzophosphate.
  • cherry fly. Outwardly it is very similar to the indoor one, but differs in its small size. Prefers late or mid-season varieties cherries. The first sign of the presence of a fly on a tree is the presence of dents and softening on the berries. Use drugs such as Diazinon, Dimethoate, etc.
  • Weevil or cherry weevil. Causes significant damage to the tree, first of all attacking buds that have not yet blossomed. When the time for flowering comes, the weevil attacks young leaves, flowers and all ovaries. You can get rid of this pest in several stages. Stage one: in the fall, peeled or old bark must be removed, and the cleaned areas are smeared with lime. It is advisable to destroy all removed bark and fallen leaves. Stage two: the area of ​​soil around the cherry root must be dug up (this is where most of the weevils prepare for wintering). And during the period of active ripening of the buds, it is imperative to get rid of weevils - just shake them off the swelling young cherry buds. Stage three: treating the tree with insecticides (it is best to do this as soon as the cherry blossom process begins).
  • Goldentail. In other words, it is called the Golden Silkworm. The damage caused by the activity of this pest is similar in appearance to that left by hawthorn. Caterpillars hatched from Goldentail eggs eat cherry leaves, then wrap them in a dense web and attach them to branches, where they spend the winter. And in the spring, young cherry buds are also eaten.

Effective folk remedies for pest control

In addition to chemicals, products made from herbs and other natural ingredients can be used as a pest control tool. For example, weevils can be controlled not only with the help of insecticides. Try making your own solution from ordinary field chamomile: pour 150 g of dried or fresh chamomile (flowers) into 15 liters warm water, leave in a dark place for 24 hours. After which the solution must be filtered and 50 g of ordinary laundry soap added to it.

cherry fly

You can certainly get rid of caterpillars and larvae of almost any cherry pest using one of the methods described below:

  1. Tomato decoction. An excellent remedy to help get rid of caterpillars. We will need 3-4 kg of tomato stems and leaves: fill them with a bucket of water and boil for 30 minutes. Let cool slightly and be sure to strain. Then you need to dilute the broth with water in a ratio of 1:3 and add laundry soap. Periodically spray the cherry foliage with the prepared decoction.
  2. Burdock decoction. To prepare it, you only need water and burdock leaves (the amount of the first and second is taken in a ratio of 2:1). Burdock must be infused in water for about 3 days.
  3. Potato infusion. Another excellent remedy that helps get rid of not only caterpillars, but also aphids. Potato tops (1 kg) are infused in 10 liters of water for 5 hours. Then you need to add 50 g of laundry soap to the finished infusion.

Advice. To prevent the possibility of the spread of larvae and caterpillars, try not to miss the moment when you should start treating the tree with the necessary preparations/agents. To minimize the possibility of pests, the soil should be dug deeply every fall to destroy the larvae at depth.

Our material is coming to an end. You are convinced that, despite the considerable number of various pests that pose a threat to the life and health of the cherry tree, there are effective means fight them. It is only important to implement preventive measures in a timely manner. We wish you a rich harvest!

Cherry trees attract not only people who wish to eat ripe fruits, but also insects. What are cherry pests and how to control them? Photos and descriptions will help you better study plant enemies and find ways to destroy them.

Fruit trees in our gardens become the subject of close attention of insects that infect almost all parts of the plantings. Leaves and ovaries, flower buds and already ripe fruits, small and large branches suffer from pests. When there is a massive infestation of aphids, caterpillars of various species, and leaf roller mites, they can cause serious damage to the garden, weaken it, or even destroy it.

Which uninvited guests are the most dangerous? How to treat cherries against pests, and when is the best time to carry out such work?


Cherry weevil

Small, golden-reddish beetles up to 5 mm long feed from early veins on cherry buds, young foliage and flowers. And such damage indicates a serious danger from pests, but weevils do not disdain filling fruits, eating away the cavities right down to the very pit. Here, cherry pests lay their eggs, and the hatching larvae continue to cause damage, destroying the core of the seed. Spoiled fruits fall off, and the larvae move from them to the ground, where they successfully pupate and wait for spring.

In early spring, when the snow has melted but the buds have not yet awakened, cherry weevils can be manually shaken off onto available materials spread under the trees, collected and burned. This method is convenient if you grow in hell low-growing varieties, but is completely unsuitable when the pest threatens large trees 5–7 meters high.

Therefore, a more competent and long-term way is to install fishing belts. They will protect the plantings not only immediately, but also throughout most of the summer.

When attacking weevils, they also use means chemical protection, and also traditional methods. How to spray cherries against pests in this case? Modern insecticides, which are used to irrigate crowns, trunks and tree trunks, help against beetles. Treatment is carried out early, after flowering and in the fall, after leaf fall.

In addition, cherries can be treated with a daily infusion of fragrant or chamomile. On a bucket hot water You will need 100 grams of plant materials and half a bar of crushed laundry soap.


Slimy and other sawfly species

If larvae appear on the leaves, which simultaneously resemble slugs and caterpillars, then the cherry tree on the site is threatened slimy sawfly. The cherry pest shown in the photo and its control should be under the special control of the gardener.

Smooth greenish-black larvae do not exceed 4–6 mm in length and appear on young foliage. Finding itself on the upper part of the leaf blade, the sawfly eats away its juicy part without touching the veins and bottom part. As a result of this exposure, the damaged tissue dries quickly, and the leaves on the tree become covered with burn-like spots. Mass infection leads to premature leaf fall, weakening of plants and poor wintering. In the fall, the larvae enter the soil, and in the spring they fly out, becoming adults, ready to reproduce as insects.

Close relatives of the described pest are no less dangerous for cherries: yellow plum and pale-legged, cherry sawflies. They also damage leaves and ovaries, and closer to autumn they move to the ground and overwinter safely at shallow depths.

To combat the sawfly, insecticides are used if this does not harm the ripening crop. With minimal infestation, the larvae are picked by hand or washed off with a stream of water onto a film or cloth spread under the tree.

Instead of chemicals for treating cherries against pests experienced gardeners It is recommended to take a strong infusion of smoking tobacco.

Cherry aphid

Cherry or black aphids appear on the tops of young branches in the first month of summer. Insect pests of cherries, which multiply quickly, cover the succulent parts of the shoots in a dense ball in a matter of days. By feeding on plant juices, aphids cause deformation of the affected leaves and stems. As a result, the garden suffers and productivity decreases:

  1. Tree growth stops or stops.
  2. Plants weaken, and fungal infections easily develop in areas damaged by aphids.
  3. The chances of getting a harvest next year are reduced.

When the cherry pest shown in the photo appears, the fight against it should consist not only of treating it with chemicals, but also of following agricultural practices.

Important:

  • reduce the population of garden ants that spread aphids to crop plants;
  • carry out competent regular pruning of diseased and fattening shoots;
  • do not get carried away with introducing excessive amounts of foliage, which provoke the formation of young foliage;
  • clean the trunk from old bark and whitewash the trunks.

In addition to treating cherries against pests using insecticides, treating plantings with an ash-soap solution and an infusion of mustard powder are also effective in the fight against aphids.

cherry fly

Seemingly harmless flies can cause no less harm. Cherry fly, for example, dangerous pest cherries, due to which you can lose almost the entire harvest. The larvae laid by insects feed on the fruits and spoil them. When the cherry falls to the ground, the grown insect goes to the surface layer of soil for the winter.

Miner flies are no less dangerous. Cherry pests are detected by the passages in the leaves. Winding tunnels inside the leaf blades indicate that the eggs laid have turned into larvae, ready to emerge and become a new generation of adult insects by spring. In case of mass infection, the leaves suffer so much that the tree cannot properly prepare for winter, as a result it freezes, gets sick, and produces a smaller harvest.

Hawthorn butterfly, goldentail and other cherry pests

Since early spring, not only bees have been circling over the cherry orchard, but also various types butterflies. Not all of them hunt for nectar. Cabbage-like hawthorn, lacewing, and cherry moth are prominent representatives of cherry pests.

Caterpillars of these species actively eat buds and foliage, so it is important to recognize the enemy as early as possible and begin to fight it. At the caterpillar stage, insects are collected by hand or sprayed with chemicals. The gardener decides how to treat cherries against pests. But when choosing an insecticide, it is important that the chemical provides long-term protection and does not harm the crop.

Since during the season many butterflies manage to produce two or three generations, the treatment is carried out not only early spring, but the appearance of foliage, but also at the end of summer.

Cherry pest control and preventive measures

No matter how fast-acting and effective modern means of insect control are, treating cherries against pests will not give the desired result if there is no competent prevention.

Throughout the season, fallen leaves are regularly collected and destroyed. The same is done with mummified, unripe fruits.

Cherry pest control, as in the photo, should involve irrigating the plants with chemicals. But this is far from the main stage. The main work is carried out in the fall and includes:

  • diseased, dry and damaged branches;
  • sections, as well as cracks in the bark and damaged areas with gum discharge are treated with garden varnish;
  • fallen leaves, branches and remaining fruits are carefully picked and burned;
  • the soil under the trees is loosened and carefully dug up;
  • with the onset of the first cold weather, the garden is sprayed with a 5% urea solution.

In the spring, the condition of the trees is checked again and comprehensive treatment against insects and diseases is carried out. fruit crops. Most often, systemic means that are effective against a whole range of hazards are used for this purpose. It is important to irrigate not only the trees themselves, but also the soil underneath them. Repeated spraying is necessary after flowering. Another treatment can be done in the summer.
