Treatment of apple trees during flowering from pests. processing during the growing season. How to treat an apple tree with various types of drugs

Every gardener who dreams of a large and high-quality harvest declares war on diseases and pests. Processing apple trees in spring is one of the main strategic operations aimed at the destruction of insects awakened after hibernation. Experienced gardeners they advise how to spray apple trees in the spring from pests in order to enjoy a rich, high-quality harvest in the fall.

Disease control and garden pests lasts all year, except for winter. Spraying apple trees in the spring provides direct contact of preparations with insects, which leads to their rapid death.

AT autumn period these procedures are more of a preventive focus. It is autumn spraying that affects the intensity of the onset of pests on horticultural crops, so they should not be underestimated either.

However, autumn work is not able to solve specific tasks in each individual case. In the spring, the gardener can clearly see the degree of insect infestation of each tree. Processing is carried out in accordance with the timing of the development of the tree.

The simplest example is pollinating insects. If hazardous insecticides are sprayed on the plants during flowering, entire bee colonies will die.

Pest control of apple trees is carried out in several stages:

1. In early spring, in March, pruning, mechanical cleaning and whitewashing are carried out.
2. In the middle of spring, in April: after the appearance of the buds, they are sprayed with solutions of iron and copper sulfate; with the appearance of leaves, ash is introduced into the trunk circle; when forming a bud, they are sprayed with biological products.
3. In late spring, from the end of April and in May, trees are treated with insecticides and fungicides, and trapping belts are installed.

The first spraying using copper sulfate, nitrofen or carbamide is carried out at a temperature of about + 5 ° C, when the kidneys are still sleeping. A variety of insects that have not yet become active during this period are eliminated in a half-asleep state.

In April-May, during the growing season, when the kidneys swell, it is recommended to use nitrofen, carbamide, copper sulfate. At this time, it is important to destroy the flower beetle (weevil), which causes great damage to the apple orchard. The tree should be sprayed when the awakened bud has started to grow, but has not yet had time to open. Too much early processing or delay even for 5 days will not bring the effect.

Before flowering (pink bud), apple trees are sprayed with Bordeaux mixture. In May, after flowering, trees are treated from aphids, mites, sawflies, codling moth caterpillars and leafworms with karbofos, benzophosphate, chlorophos. Having changed the drug, so that resistance to it does not appear, it is recommended to repeat the treatment after 2 weeks.

Work technology

Spraying equipment is selected based on the size of the garden. Mechanical device with hand pump suitable for small garden with low plants. For processing a garden with a large number of trees, it is much faster and more convenient to use an automatic accumulator or gasoline machine, which also consumes the product more economically and evenly.

In any case, an extension cord is needed, with which they process tall trees. When choosing a device, you should pay attention to the sprayer, which should spray the mixture evenly over the surface. After completion of work, the device should be thoroughly rinsed. cold water.

It is more efficient to process the entire garden at one time. It is better to do this in the evening, in dry calm weather, if the air temperature is not higher than + 30 ° C. The agent should be sprayed evenly over the entire surface of the trunk, branches and leaves, including back side. The soil around the trunk also needs to be cultivated.

The distance between the sprayer and the sprayed surface must be maintained at least 70 centimeters. When working with fungicides, the solution in the tank of the device must be shaken periodically, as the mixture may separate and its effectiveness will decrease.

Spring processing of apple trees

The first stage of spring processing is usually carried out from mid-March, when the air warms up to +5°C. Its main goal is the prevention of tree diseases and the destruction of still inactive pests that have overwintered in the bark. Apple trees need to be processed chemicals before the buds swell, as they can burn them due to their acidity.

It is best to alternately use fungicides and insecticides or use complex products. Before starting treatment, it is recommended to cut the crown, clean the trunks of dead bark and lichens, clean the damaged areas and remove the fallen old leaves. Lime can be used to whitewash trunks both before and after processing.

At this stage, the following drugs are most often used:

1. Solution of copper sulphate (copper sulfate)- a fungicide that disinfects the soil and wounds, prevents fungal diseases, rotting. The product is prepared by dissolving 100 grams of copper sulfate in 10 liters of water. For one tree up to 7 years old, 2 liters of this mixture is enough; for older trees, the volume should be increased.
2. Nitrofen- a complex preparation, the action of which is aimed at preventing the occurrence of curliness, scab, powdery mildew, spotting, and the destruction of pathogens of fungal diseases, pests and their eggs that have overwintered in fallen leaves. To prepare the product, 300 milliliters of nitrofen are diluted in 10 liters of water.
3. Urea (urea) solution- effectively fights against weevil, aphids, sucker, flower beetle, provides effective protection from spotting, scab and other diseases. By saturating the tree and soil with nitrogen, urea has a positive effect on productivity. For spraying, a solution is prepared from 10 liters of water and 500 grams of urea. If last year there were a large number of pests, you can make the product more concentrated (700 grams per 10 liters of water).

The second stage of processing is carried out with the beginning of bud break, flowering has not yet begun. This period lasts from late March to mid-April.

The treatment is aimed at combating scab and fruit rot and the destruction of emerging hibernation mites, suckers, flower beetles, scale insects and other insects that feed on leaves.

The following tools are used at this stage:

1. ferrous sulfate solution(iron vitriol) - does not guarantee complete extermination of insects, but destroys about 50% of the eggs of the sucker and similar pests, provides wound healing and disinfection, is effective against lichen, rot and moss, saturates apple trees and the soil around them with iron, which is required for growth. Prepare the product by dissolving 1 kilogram of the drug in 15 liters of water.
2. Bordeaux liquid- a fungicide consisting of lime and copper sulfate. To prepare Bordeaux liquid, 300 grams of lime and blue vitriol are stirred each separately in 3 liters hot water. You can use any cookware except aluminum. The resulting solution is brought to 5 liters with cold water. A mixture of lime is poured into a solution of vitriol in a small stream, resulting in 10 liters of Bordeaux liquid. The solution should be blue. They check it with litmus paper, which should turn blue, or a clean nail, which should not turn red from copper in the solution. Otherwise, add more lime.
3. colloidal sulfur- compatible with many fungicides (with the exception of ferrous sulfate and organophosphorus preparations) against ticks and fungal diseases. The solution is prepared by gradually adding 80 grams of the drug to 10 liters of water with constant stirring until a homogeneous suspension. Use it immediately after preparation. The agent begins to act 3 hours after spraying, effectively for 12 days.
4. Lepidocide- designed to control leaf-eating insects biological preparation intestinal action. For pollinating insects, the product is harmless. When it enters the intestines of the pest, it causes paralysis and subsequent death. The action of the product begins 4 hours after use. The prepared solution (70 milliliters of the drug per 6 liters of water) should be used within a day.

The final stage of spring processing is carried out in May, after flowering. Its purpose is to fight diseases that have arisen and destroy leafworms, aphids, mites, codling moth caterpillars, weevils, and moths. Immediately after the end of the flowering period, you can repeat the second stage.

After 3 weeks after the flowering of apple trees, for care it is necessary to spray them with the following preparations:

1. Benzophosphate- effective against leaf-eating and sucking insect pests, intestinal insecticide. The action of the drug lasts for 15 days. It does little harm to grinder larvae and bees. To prepare a solution for 10 liters of water, 70 grams of the substance is used. You can use benzophosphate no more than 2 times per season.
2. Karbofos- an insecticide that works well against the codling moth, weevil, aphids, leafworms, mites, scale insects. Dangerous for bees. Prepare a solution for processing at the rate of 60 grams of the drug per 10 liters of water. The norm for young apple trees is about 2 liters per 1 tree, for adults and fruiting ones - up to 10 liters.
3. Chlorophos- has an intestinal effect systemic insecticide. For aphids and weevil, the drug is of low toxicity, for some species of beetles and ticks, mosquitoes, adult flies and larvae, it is poisonous. Valid for 10 days after treatment. To prepare a working solution in 10 liters of water, dilute 70 grams of the drug. It is impossible to add a product to Bordeaux liquid.

Precautionary measures

In the manufacture of solutions, it is imperative to observe the norms of dosage of drugs indicated in the instructions. It is also worth paying attention to the lines of their validity. Solutions are prepared immediately before use, preferably in a separate room. The function of the spraying device must be checked before operation.

Regardless of the type of agent used for processing, the spraying process is carried out in a protective suit, special glasses, rubber gloves, gauze bandage or a respirator. One spraying cycle should not last more than 6 hours. After finishing work, rinse your mouth with simple soap without additives (to avoid negative chemical reaction) wash your hands and face. Wash the protective suit in the same way, rinse the equipment.

The garden must not be cultivated strong wind, in the scorching sun, just after the rain. Children and pets should not be in the garden during processing. It is not recommended to spray funds on apple trees during flowering: this can lead to the death of the crop.

When processing young branches, the solution must first be tested on several branches of the same tree. If after 2 days there are no burns of young bark and leaves, you can safely use the product for the entire garden. If burns appear, the concentration of the drug should be reduced or another one with a lower acidity should be chosen.

When grown on personal plot apple trees and other fruit trees, gardeners invariably face the problem of pests. The fight against them consists both in preventive work in the garden, and spraying trees with various insecticides to destroy such insects. We will tell you in more detail how the apple orchard is processed in the spring, we will also talk about when and how to process apple trees.

Common pests of apple trees

Various insects can be a real problem for apple trees and other fruit trees. They are destroy foliage, spoil the bark and feed on the pulp apples ripening on a tree. Regardless of the specific harvest eater, it is necessary to start fighting it as early as possible, which will help to cope with the existing problems.

One of the most common and dangerous pests apple tree is a codling moth. Even before flowering, this small nondescript butterfly lays numerous eggs on an apple tree, and later voracious larvae hatch from such eggs, making their way inside the ripening fruits and feeding on the pulp. Such a codling moth can completely destroy the entire crop in a short time.

Also, when growing apples, problems can be delivered mites, moth, aphids and other insects that, without proper attention from the gardener and with improper care outside the garden, they quickly multiply on fruit trees, inhibit plantings and reduce the yield of apple trees.

We spray apple trees from pests

Preventive spraying of the garden can be performed in spring and autumn. After completing this work in early spring before flowering, gardener destroys eggs and larvae hibernating in the bark, preventing the subsequent appearance of such pests on trees. By treating the apple tree before buds form on the tree, it is possible to use strong insecticides that effectively destroy insect pests and pathogens, being an excellent prevention against the occurrence of similar problems in the future.

We can recommend that you spraying apple trees before flowering endosulfan. It is an effective and easy-to-use insecticide that can be applied manually or with a variety of spray guns. Experts recommend performing several sprays with such an agrochemical, and the interval between treatments is approximately two weeks.

Each tool is distinguished by its toxicity, so you need to familiarize yourself with its use in the instructions.

efficient universal remedy for the prevention of the fight against diseases of apple trees is the agrochemical oleocuprite. It must be used in full accordance with the instructions.

For spring processing of apple trees, you can use the following agrochemicals:

• Karbofos.
• Benzophosphate.
• Speed
• Bordeaux mixture.
• Nitrafen.
• Urea solution.
• Lepidocide.
• Chlorophos.

Mature and old diseased trees can also be sprayed iron vitriol, which allows you to feed the planting and destroy various pests.

We process the garden in spring in three stages

First spring processing apple trees is carried out in March, simultaneously with crown pruning and cleaning of trees from lichen and dead bark. The main purpose of this processing is prevention of various diseases. For such spraying, we can recommend the use of copper sulfate, urea solution and nitrafen.

The second spraying of landings is carried out before flowering. With the help of Bordeaux liquid, colloidal sulfur or lepidocide, pests such as leaf beetles, scale insects, aphids and other pests can be destroyed.

• In spring, processing should be carried out at air temperatures of at least 5 degrees.
• This work is done before the kidneys swell.
• For processing, it is best to choose calm cloudy weather.
• Such processing should be carried out in three stages.
• Wear appropriate personal protective equipment, including goggles and a respirator.

Destroy insect pests

As soon as you find various insect pests on the apple tree, it is necessary to process the plantings as soon as possible. We recommend that you use universal insecticides that combine efficiency and ease of use. For example, you can use Decis Expert or Calypso insecticide. Such agrochemicals are easy to use and help to cope with various insects, destroying both adult larvae and microscopic eggs in the foliage and on the bark.

The use of universal insecticides involves several tree treatments, which allows you to completely destroy insect pests. Planting should be sprayed in accordance with the recommendations in the instructions for each specific tool, which will guarantee a complete solution to the problem with various insects.

Modern insecticides are environmentally friendly and completely safe means , which can be used even if there is a ripening crop on the tree. Yet most gardeners recommend that the last treatment with such insecticides be carried out no later than two weeks before harvest.

Folk remedies for pest control on an apple tree

Excellent efficiency is shown by various folk remedies insect pest control on fruit trees. We can recommend you treat your garden with homemade spray, which is prepared hot pepper and garlic. To prepare such a tool for treating trees, it is necessary to grind half a glass of hot pepper and garlic, mix the resulting mass with a bucket of water and gently spray the trees. Such products do an excellent job with the codling moth, repel slugs and other insects. It is only necessary to use such a spray when the gardener notices the first signs of diseases and pests.

Conclusion

Spring spraying of apple trees in the garden with insecticides of universal action will prevent the appearance of various insect pests on the trees. Also, the gardener can use such agrochemicals to control moths, aphids and other pests. It is only necessary to use such means as soon as possible, after you notice such pests on the apple tree, which will allow you to easily cope with the existing problems, and the gardener will receive excellent harvest delicious and healthy apples. In this article, we told you when and how to spray plantings against diseases and insects that can cause a lot of problems for the gardener.

In order to get a good, healthy, rich harvest in the garden, it is necessary to properly care for the trees. Yes, one of key points is a treatment of plants that helps protect trees from attack by pests and various diseases. The processing of an apple tree has its own characteristics, so spraying before flowering and after is noticeably different and has certain rules.

If the necessary procedures for the processing of apple trees are carried out in time, this will help to avoid many troubles in the future regarding the flowering and productivity of the apple tree. Thus, it is possible to get rid of various pests and diseases.

It is important to understand that the process takes place in several stages, taking into account the flowering period of the tree. So, at a time when the flowers on the branches have not yet appeared, the processing process takes place with the participation of some means, and after flowering completely different.

Processing an apple tree is a very responsible event that requires attention, strength, knowledge and desire.

Before flowering

Until the moment when the first flowers appear on the tree, the processing procedure is as follows.

The first stage falls on the middle of March. It is important that the air warms up to +5 degrees, and this figure is stable. At this time, they deal with those pests that have wintered together with the tree, but have not yet entered the active stage. Spend preventive measures from various diseases.

Until the moment the buds swell, it is possible to spray with chemicals, including special fungicidal and insecticidal ones. The main thing is that before you process a tree, you first need to cut the crown, and remove the old bark that has died from the trunk. The damaged segments are cleaned, last year's foliage is removed.

At the next stage, when the buds open, but the flowering itself has not yet begun, they begin to get rid of aphids, mites, apple beetles, scale insects, suckers and other small insects. This time period is from the end of March to mid-April. During the same period topical issue is the elimination of scab and fruit rot. To do this, they can use a solution of copper sulfate, vitriol, Bordeaux liquid, colloidal sulfur and a special intestinal preparation to repel gnawing insects.

After flowering

During this period, when spring already completely dominates, and the flowers have already faded, with the help of properly selected preparations, you can get rid of caterpillars, apple codling moths, weevils, aphids, moths and other pests in a timely manner.

The first stage is carried out in the spring immediately after the flowers have left the branches. The second treatment period is done 21 days after the first treatment.

There are several features of spraying an apple tree after it has faded in the spring. It doesn’t matter what this procedure will be used with, you need to know a few “iron” nuances.

To begin with, prepare the liquid, the appropriate inventory, protective equipment in order to start the spraying process in the spring.

Columnar apple trees lend themselves to this process most easily. A fungicidal liquid is sprayed onto it, bypassing the tree itself in a circle. It is very convenient that you do not need to look for a ladder, carry out the procedure at a height in an uncomfortable position.

The procedure is more complicated with young apple trees, it is important not to miss a single branch and carefully distribute the liquid. Another important point is the fact that the use of too concentrated solutions can harm the tree and the future harvest. To test the young animals for the endurance of the sprayed agent, it is necessary to conduct a test for burns. To do this, choose one branch and spray it with the prepared liquid. After 2-3 days, carefully examine it. If the apple tree looks healthy, no spots, damage, dots, defects, etc. have appeared on it, then the rest of the plants in the garden can be treated with this composition.

What to process

In the spring, after flowering, in order to get rid of aphids, mites, scab and other pests, you can use fungicidal preparations or sodium phosphate at the rate of 10 per 1 liter of water. Apply special agent"Skor", it is bred, step by step following the instructions.

In order to defeat shag, as well as aphids, tobacco tincture (400 g per 10 liters of water) or shag is perfect. The resulting "cocktail" is further diluted 10 times with water and 40 g of soap are added. The resulting mixture, in the spring, is treated with plants.

Another alternative in the fight against insect pests such as aphids, scabs, mites, you can use a tincture of a decoction of tomato leaves, wormwood, dandelion, potatoes or yarrow.

Some gardeners practice treating trees with urea or copper sulfate, only this is not done in early spring, but after the apple tree has completely faded.

The effectiveness of the event, and getting rid of aphids, mites, scab, weevils, etc., depends on the time of the spraying procedure. After a few weeks, the field of the first spraying can be used such preparations:

• "Benzophosphate". This is a special insecticide of intestinal action. It copes well with pests that eat leaves. But completely inactive in relation to bees and larvae. In order to prepare the desired liquid, a 10% substance weighing 70 g is used and 10 liters of water are added. The prepared solution can be used for 15 days, it is during this time that the necessary qualities are preserved.
• Karbofos. This insecticide perfectly deals with aphids, weevils and mites, scale insects, scab. It is also poisonous to bees, so if there is an apiary on the site, the use of such a drug is not recommended. Prepare a solution based on the ratio for every 60 g of the substance 10 liters of water. It is important to know that two liters each is enough for young trees, but an adult "individual" needs at least 10 liters of liquid.
• "Chlorophos". Perfectly cope with aphids thanks to this tool will not work. But it destroys larvae, mosquitoes, flies, some beetles and ticks. It is diluted from the consumption for every 10 liters of water, 70 g of the substance. Retains its qualities for 10 days.

Whatever drug is used, you must carefully follow the instructions.

Pest control

Very often the scab affects the apple tree. This fungal disease is very dangerous for the crop. Due to the fact that such an ailment is formed, the process of photosynthesis on the leaves worsens, the fruits are wrinkled and spotty. Scab appears as olive spots on barely opened buds. Fungicides are used to combat this problem. You can use drugs: Gamair, Horus, Fitolavin, Strobi. Various Methods there are many to eliminate scab, and you can choose the most suitable one, based on the degree of the disease.

Aphids can infect apple trees. It is quite difficult to deal with it. Aphids strongly affect the fruits and speak on the very development of the tree. To combat aphids, you can use tobacco infusion, ash or other drugs.

The apple tree can be affected by a tick. There are several types of them, but each has a detrimental effect on this fruit tree. The previously considered drug "Karbofos" helps to overcome this ailment. You can also use an infusion of garlic or a decoction of bitter pepper.

Whatever the pests, it must be dealt with and every spring a series of events should be carried out.

In addition to the selection of the solution and the method of spraying, the "iron" rule is to observe the period of spraying liquids and treating trees. In the case when all the activities are carried out correctly in the spring, the tree grows healthy and gives a wonderful rich harvest.

Foreword

The experience of every gardener proves that if you want a large and high-quality harvest, declare war on all insects and pests! Processing apple trees in the spring, when they wake up after hibernation, is precisely the most important "military" operation!

Processing apple trees in spring - tactics and strategy!

Pest control continues almost all seasons, except perhaps for winter. In spring, spraying apple trees leads to direct contact of preparations with insects and their rapid death, while in autumn these procedures are more likely to be preventive. However, it depends on the autumn spraying how intensively the pests will counterattack on your garden, so you should not underestimate them either.

However, autumn work is not able to solve specific problems in each individual case. In the spring, the gardener sees and evaluates the degree of "infection" of the tree with insects. Of course, you do not need to grab the drugs and sprayer every time you see a suspicious butterfly flying over the trees - each treatment should correspond to the timing of the tree's development. The simplest example is related to pollinators - imagine what it would be like for them to pollinate plants treated with dangerous insecticides during flowering. This is how entire bee colonies die.

The fight against diseases of apple trees and pests is carried out in several stages:

1. Early spring (March) - mechanical cleaning, pruning, whitewashing.
2. Mid-spring (April):
   the appearance of kidneys - spraying with solutions of copper and iron sulfate;
   the appearance of leaves - the introduction of ash into the near-trunk circle;
   the formation of a green cone and the promotion of a bud - spraying with biological products.
3. Late spring (late April-May) - treatment with fungicides and insecticides, installation of trapping belts.

Pest controlearlyspring - preparatory stage

Apple pest control is not only spraying trees in the spring.In early spring, early to mid-March,chemical exposure better postpone put aside, but for starters take take a pruner. Together with shortening and shaping the crown, clean the trunks of apple trees from lichens and exfoliated bark - wintering places for many insects.

It is in early spring that the sun, which begins to warm up, coupled with frosts that do not want to give up their positions, cause serious damage to trees, including apple trees, - sun-frost burns. In the first month of spring, whitewashing of trunks can be recommended, which has a combined effect - it will protect both from burns and pests. For this purpose, you can use either acrylic paint, or a self-prepared mixture, diluting 300 g of lime (for young apple trees - chalk) and 2 tablespoons of clerical glue in 2 liters of water. The reminder to treat the process without fanaticism remains relevant: it is better to refresh the whitewash after a while than to apply it the first time in three layers.

What to do while the kidneys have not yet woken up

Measures to protect against diseases and pests, in particular aboutspraying them with chemicalswe undertake strictly in accordance with the phases of awakening the tree from winter sleep.The first is the period before bud break. Only at this time it is possible to process apple trees from lichens and tinder fungus. For this, a 5% solution of ferrous sulfate is perfect (diluted in 10 liters of water500 g of iron sulfate)or 5% Bordeaux mixture, consisting of lime and copper sulfate. In both the first and second versions, 500 g of powder is diluted in 10 liters of water.

In order to fight ants, they also cover the trunk with garlic arrows and tar. You need to be careful with the latter, as this method can cause wood burns. For further processing of apple trees in the spring from pests, each gardener can choose both biological products, for example Lepidocide, and chemicals, for example Preparation №30.
Mid April and early May - the time of the formation of the green cone and the extension of the bud. These days trees are attacked by green apple aphids, bud weevil, fruit sawfly, leafworm and many other insects that can ruin your crop even before it appears.

These days, gardeners are "arming themselves" with drugs such as Calypso, Horus, Aktofit, Topaz, as well as re-treatment with biological products. Great solution in the middle of spring, the crowns of apple trees will be sprayed with a solution of urea, taken at the rate of 100 g per 10 liters of water. Its more saturated solution (650 g per 10 liters of water) is suitable for processing the trunk at the border with the ground.

How to protect a tree at the bud stage

In late April-May, the stage of pinking of the buds begins. It was at this time that apple trees are especially vulnerable to infection with fungal diseases (fruit rot - moniliosis, scab) and it is worth taking their protection seriously. Nice results brings treatment with chemical or biological fungicides - 1% Bordeaux mixture, Horus or Fitosporin-M.

Protection after flowering

Unfortunately, the fight against pests that can ruin the crop does not end with flowering. 2 weeks after the end of the flowering of the apple tree, it is recommended to re-spray from fungal diseases and pests, among which the apple codling moth becomes especially active at this time, the caterpillars of which crawl out of the oviposition just in late spring, at the very end of May. For these purposes, use Fitoverm, Aktofit, Match, Fitosporin, Urea K-2. It is important to combine, change these drugs, focusing on the mode of their action.

In the question of how to process apple trees in the spring, be guided by the following considerations - effective pest control requires both contact and systemic preparations. Contact hit the insect, falling directly on it. However, after a week they will lose their strength or be washed away by rain, although they will eliminate pests after processing. But systemic drugs penetrate the plant, poisoning its juices.

This does not affect the fruits, since at the time of ripening insecticides decompose into non-hazardous components. Combining different drugs, you will achieve the greatest effectiveness of your actions!

In order to reduce the possible negative effect on the apple trees of the means by which the treatment is carried out, it is worth using their combinations in order to carry out spraying at a time from maximum number pests. Among these drugs, we can recommend "Fitoverm".

In regions with a warm climate, for the same purpose, already at the end of May, so-called “trapping belts” can be used, environmentally friendly mechanical traps for harmful insects. Such "traps" can be bought in stores or made by yourself, which is quite simple. There are dry, poisonous and sticky belts. Made from rubber, cardboard, plastic, polyethylene film etc. The main goal is to catch most of the harmful insects moving along the trunk to the crown and back.
