If you have cobwebs on your apple trees, how to fight them using proven methods?

Caterpillars are larvae that eat the tissue of apple tree leaves, leaving behind nothing but veins. Although their feeding area is fairly localized, all species can cause severe defoliation (loss of foliage), stress apple trees, and reduce yields. In addition, they are all very unsightly to our eyes and greatly spoil the landscape. In addition to caterpillars, apple trees are damaged in June by aphids (you can learn about this from this material), and some strange pest that weaves complex bags of cobwebs at the ends of the branches.

What diseases and pests cause spider webs?

If you see gray-yellow caterpillars in a thick, massive, dense web, you have codling moth.

If you notice a white, dense web all over the tree, it's an apple worm . Its larvae suck the juices out of the plant, and then secrete a sticky substance that glues the buds, foliage, and buds together, resulting in the formation of a sooty fungus, which we see as a white cobweb.

If you find clearly visible cocoons on apple trees , you will understand that the trees have been affected by hawthorn. These are small caterpillars that curl up and overwinter in cocoons.

But when a spider mite appears, you will see a web in the form of transparent cloudy films with many black very small dots - these are eggs.

Sapwood and bark beetle: harmful beetles

There are several types of these pests that appear after the apple tree blooms.

Sapwood is a shiny black bug that feeds on tree bark and causes great damage. Without proper treatment, the apple tree will simply die.

Beetle larvae overwinter in cracks in the bark and trunk, and in early spring they feed on tree sap, gnaw holes and come out. Females give birth to large offspring and do not die for a long time.

Important! If bark beetles appear on an apple tree, then the entire garden must be repeatedly treated for fungal diseases. To get rid of pests, clean your garden thoroughly in the fall.

In early spring, pour boiling water over the tree to kill all pests. In winter, dig up the tree trunk when stable frosty weather sets in

To get rid of pests, clean your garden thoroughly in the fall. In early spring, pour boiling water over the tree to kill all pests. In winter, dig up the tree trunk circle when stable frosty weather sets in.

Wounds and cracks in the bark are cleaned and treated with 1% copper sulfate, after which they are carefully sealed. This is the most effective remedy against diseases and pests.

In conclusion, it is worth noting that a tree is rarely affected by one type of pest, so complex preparations offer protection in several directions at once. Carefully monitor the condition of the apple trees in order to take timely measures to combat pests.

A cobweb on an apple tree is a sign that the tree has been taken over by a pest. Spiders, of course, also weave webs on trees, but the thick and dense ones are usually left by insects that feed on the leaves, flowers and buds of the tree. If you do not deal with them in time, the tree may die.

Apple tree in a web: what to do with spider moths?

This is a small snow-white butterfly ; it lays many eggs in the form of scutes, choosing young branches and protected places: on the forks of branches, at the base of the buds. Caterpillars spend the winter under the egg shells. In early spring they chew off the buds and then eat the leaves.

The leaves dry, and the caterpillars create a web in which 20-70 of them live. Afterwards they form pupae, and at the beginning of summer butterflies emerge from them and again lay up to 100 eggs under the scutes.

In the fall, take a magnifying glass and examine the young branches of the apple tree. If you see egg scales, scrape them off and burn them, cut off damaged and dry branches and burn them, and before winter, spray the apple tree with milk of lime.

In early spring, cut and burn the scutes. When the buds begin to bloom, and before the buds grow and separate, spray the trees with: a solution of 2 ml Decis per bucket of water or a composition of 4 ml Fitoverm per bucket of water, a solution of 10 ml Kinmiks per bucket of water, a solution of 10 ml Kemifos per bucket of water .

You can use the product by diluting 1 Inta-Vir tablet in a bucket of water . If there are a very large number of insects, then treat the apple trees with a solution of 10 ml of fufanon per bucket of water.

Processing times

To protect the apple tree from spider mites and other pests, there is an established order in which spraying should be carried out during the growing season.

Before the buds open

The first spring treatment is carried out to destroy ticks and other insects that have overwintered on the apple tree.

Before the buds open in March, at temperatures not lower than 5 ºC, you can spray the trees with a solution of copper or iron sulfate. Also treat the soil around the apple tree with this solution, because many pests also overwinter in it.

After bud break

The next spraying should be carried out after the buds open and before flowering begins (in May). Treatment can be carried out with any of the insecticides or acaricides mentioned above.

During flowering

Spraying during flowering is undesirable. Chemical exposure during this period can negatively affect the harvest and cause the death of bees and other beneficial insects.

Spraying should be carried out only as a last resort, if you were unable to treat the trees against mites before flowering, and their numbers pose a threat to the apple tree.

During fruiting

The next treatment should be carried out at the beginning of fruit growth (June). The same insecticides should not be used several times in a row.

ATTENTION! You cannot spray apple trees while the fruits are ripening; the last treatment with chemicals should be carried out on average a month before harvest!

Damaged fruits and branches are removed and burned.

Final processing

The last treatment is carried out after harvesting and before the leaves fall with insecticides, copper sulfate or urea, to destroy mites that have remained through the winter.

If there are caterpillars in the web (black, gray, green)?

• If you find almost black caterpillars in the web, with bluish stripes on the back, this is a ringed silkworm . They sit motionless all day, and at night they feed heavily on leaves and flowers.

To repel caterpillars, use tinctures of wormwood or milkweed, spraying apple trees before the buds open. You can use “Lepidocid” and “Bitoxibacillin”, but they can only be used at temperatures above +15°C.

• Let's say you notice green caterpillars on a tree in a web; these are winter moths . Each caterpillar has one dark and 3 light stripes on its sides. These caterpillars crawl inside the buds and eat them, and in later spring they feed on foliage and flowers. To catch caterpillars in the fall, put fishing belts on the trunks.
• If you see gray caterpillars in a web that are covered with hairs coming from tufts, these are gypsy moths . They are easily carried by the wind from tree to tree.

Advice. In the spring, carefully examine all the trunks; if you see masonry, scrape them off with a knife and treat them with kerosene.

The codling moth is the main enemy of fruit plants

If you notice that the leaves on your apple tree have curled into a tube and are covered with a network of thin cobwebs, then it’s time to sound the alarm; an apple moth has taken up residence in the garden. An inconspicuous gray butterfly, flying mainly in the evening, is the main enemy of fruit plantings. Unfortunately, it affects not only the apple tree; plums, pears and even peaches and apricots become targets for attack.

The apple codling moth appears when the surrounding air warms up to + 15 - 20 degrees, and immediately begins to multiply intensively, laying eggs on leaf blades and unripe apples. Very soon the caterpillars emerge from the clutch, and it is they who lead to the curling of the leaves and the formation of cobwebs.

Pick one affected leaf from the tree and unfold it; you will probably find a light pink caterpillar no larger than 20 mm in size. It can also be found in apples. Such fruits rarely reach technical ripeness; they usually fall to the ground. And those that do manage to ripen are greatly spoiled. They are not stored and have absolutely no marketable appearance.

If there is a cobweb on a young apple tree

If you see a web on a young apple tree, it could be an apple psyllid . These are quite small insects, up to 3 mm in size. They lay yellowish-orange eggs for the winter, placing them in inconspicuous places, in folds of bark and ringlets.

Larvae hatch from the eggs in the spring, they suck the juice from the buds and secrete excrement - these are sticky balls that blur, and all parts of the apple tree become shrouded in honeydew, and sooty fungus settles on it .

This causes the foliage and flowers to turn black and then dry out. When the apple tree fades, the larvae grow to adult green psyllids with transparent wings; they lay eggs again at the end of summer.

To eliminate the larvae, when the growing season has already begun, sprinkle the crop with an infusion of ash, yarrow, tobacco, a solution of soap, and shag.

To kill adult insects, you can fumigate apple trees with tobacco smoke.

Make piles of straw, sprinkle 2 kg of tobacco dust on each, let the piles burn for 2 hours, then the copperheads will fall to the ground. Dig up the soil immediately before the insects wake up.

Also read about other ways to care for an apple tree, such as whitewashing and tying up fruit trees.

Active control measures

Treating an apple tree for spider mites is possible using different means. Most often, chemical means of protection are used, but you can try effective folk remedies for destroying the pest, biological techniques, and agrotechnical methods.

There are numerous measures to combat ticks:

1. The use of chemical protective agents - insecticides: Fufanon KE, Karate-Zeon, Fitoverm, Karbofos and acaricides: Apollo KS, Tsipi Plus KE, Zolon KE, Mavrik VE, Omayt SP.
2. They use preparations based on biological plant protection products, for example, Fitoverm CE, Forbid 4F, Aversectin S (effective only on adult insects). Such drugs cannot completely destroy the population, but they significantly reduce its numbers. Typically, biological products are used during the fruiting period as safe means.
3. The use of folk remedies with odorous liquids: garlic solution (50 g per 10 l), sulfur-tar soap (100 g per 10 l), onion infusion (200 g per 10 l), horseradish infusion (400 g per 10 l).
4. Use of sulfur preparations such as Culumus.

Important! Chemicals are used only in dry and windless weather, using personal protective equipment: mask, goggles, gloves, work clothes. Acaricides very effectively destroy ticks and larvae, but these products are allowed to be used no more than twice a season

They are drugs of contact-intestinal action. Waiting period before picking apples – 36 days

Acaricides are very effective in destroying ticks and larvae, but these products are allowed to be used no more than twice a season. They are drugs of contact-intestinal action. The waiting period before picking apples is 36 days.

Considering that mites reproduce at least 5 times, it can be assumed that double treatment with even a potent substance is insufficient. Moreover, you cannot expect that all ticks and larvae will come into contact with the drug.

Therefore, in addition to chemical protection, it is worth using various means, alternating their use. A very effective way to combat spider mites is to use tobacco infusion:

1. A kilogram of tobacco dust is diluted in a bucket, filtered and water is added to 20 liters.
2. Laundry soap is added to the infusion by grating 50 g. This helps the product adhere better to the surface of the leaves.
3. The apple tree is treated with tobacco infusion twice, and repeated spraying is done after a week.

Ticks die when the plant is fumigated with tobacco smoke. This method is effective in protecting seedlings and young trees. But in old plantings one can hardly expect a great effect.

The use of field chamomile infusion gives good results. It is prepared and used in the same way as tobacco dust infusion.

The use of sulfur in the fight against ticks gives good results only at temperatures of +27–32 degrees. There is no point in using the drug in cold or very hot weather; there will be no results. This is due to a certain temperature when sublimation of sulfur begins to form sulfur vapors that kill parasites.

High air humidity increases the toxicity of the drug; treatment is done during dew or after watering.

Means to combat spider mites should be used at strictly defined times:

• before buds open;
• before flowering begins;
• during fruit formation.

Processing must be carried out in the following sequence:

1. The first treatment in March is used to destroy overwintered individuals. A solution of 3% Bordeaux mixture or copper sulfate is used before the leaves bloom, and the tree and the ground around it are treated.
2. The second treatment is carried out in May. At this time, you can use any insecticide or acaricide that is effective against spider mites.
3. The third spraying is usually carried out in June, during fruit growth. At this time, it is advisable to use harmless folk remedies or biological products.

Important! All leaves should be treated not only from above, but also from below, directing the spray jet from bottom to top. The final fourth treatment is carried out in the fall after harvesting the fruits.

Before leaf fall begins, the tree is sprayed with insecticides, 1% copper sulfate solution or urea, to kill wintering insects

The final fourth treatment is carried out in the fall after fruit harvesting. Before leaf fall begins, the tree is sprayed with insecticides, a 1% solution of copper sulfate or urea, to kill wintering insects.

Important! Ticks very quickly develop immunity to any chemicals. Therefore, the preparations for treatment must be changed every time.

What to do if you see red bugs?

Possibly a red spider mite . Females are 0.5 mm long and have a purple tint, bright scarlet males are even smaller - 0.3 mm.

The appearance of a tick can be noticed:

• If there are cream, scarlet or silver spots on the leaves.
• On the back of the leaves there are slightly noticeable white spots - these are mite larvae.
• If a small cobweb appears on the leaves of the apple tree.

To kill insects, spray the apple tree with bicol and verticillin.

Herbal infusions

If you don’t have time to soak infusions, you can prepare decoctions. They can be used immediately after preparation. Experienced gardeners are convinced of the effectiveness of the following recipes:

Tobacco dust

Dry, powdered tobacco leaves, in an amount of 200 g, are placed in 5 liters of boiling water and simmered over low heat under a lid for 2 hours.

After cooling, filter and spray the apple tree.

Pepper infusion

Recipe:

Boil 100 g of fresh hot pepper pods (or 50 g of dry, ground) over low heat with the lid closed for 1 hour. The result is a concentrate.

Tip #2. Before treating an apple tree for aphids, the broth must be filtered through a thick sieve or gauze. If pepper particles get on the leaves, they will cause burns.

• The working solution must be prepared from filtered concentrate diluted with water in a ratio of 1:10.
• For better adhesion of the pepper broth to the leaves, you can add 40 g of crushed laundry soap. The solution must be thoroughly stirred until the soap lumps are completely dissolved.

What to do if there are spider mites in the leaves?

In addition to the red spider mite, there are many types of mites of different colors. Ticks drink the sap, so by July half of the leaves have fallen from the tree.

You can spray the apple tree with tobacco infusion. Pour 1 kg of tobacco dust into a container and pour in a bucket of water.

Then strain and pour in another 10 liters. Then add 50 g of grated laundry soap so that the solution sticks to the surface of the leaves. Apply the composition 2 times at intervals of a week.

Dry 1 kg of chamomile flowers, pour into a bucket of water and leave for 10 hours. Then strain and spray with the composition 2 times again at intervals of a week. If there are a lot of flares, then you will have to use chemicals.

Important! Nitrofen is also used, but this is a very strong poison; it cannot be used closer than 200 m from a living space. But spider mites can be killed with bioinsecticides; they are the safest to use compared to chemicals, these are bitoxybacillin and bicol.

We must not forget about prevention: collect fallen leaves, cut off branches, burn them, clean off old bark with metal brushes and burn it.

How to get rid of a pest?

There are several ways to protect apple trees from mite invasion. This is the use of chemical and biologically active drugs with systemic effects, using agrotechnical methods or folk remedies.

Chemical plant protection products

A group of drugs used to control harmful insects is called insecticides. Those that act against spider mites are called acaricides. They are a concentrated toxic substance in the form of an emulsion, suspension, powder or solution.

It should be taken into account that all insecticides and acaricides are strong poisons; it is necessary to work with them with the utmost caution, strictly following safety rules

To rid the garden of apple mites, it is recommended to choose products with limited impact. These are “Sunmite SP”, “Omite SP” and the like. They do not destroy beneficial insects, but only affect the productive ability of mites.

Unfortunately, the use of such drugs is fraught with the accumulation of substances harmful to human health in the fruits.

Biological plant protection products

They are fundamentally different from the chemical method. Its essence is not poisoning insects with poisons, but exposing them to bacteria, which lead to the death of parasites. Such drugs are usually called systemic agents.

Biological plant protection products contain live bacteria that are deadly to this insect. These bacteria are isolated from the fungi Streptomyces. They enter the body of an adult tick along with the sap of the plant. That is, after spraying, these bacteria first penetrate into the plants themselves, and only then into the body of the mites. Under their influence, adults die.

The disadvantage of such drugs is that they are not able to destroy spider mite eggs or larvae. They are used only in late spring and summer, when it is warm outside, since at low temperatures the fungal bacteria die.

The advantages include environmental safety and a fairly long period of exposure.

Agrotechnical protection measures

The essence of agrotechnical control measures is to manually remove the affected parts of the tree. All torn leaves and cut branches are subject to mandatory burning. You should also burn the bark that has fallen from apple trees, as it may contain spider mite eggs.

Folk methods of protection

These products most often do not destroy, but repel the tick. They can be used quite successfully for prevention. Here are some folk recipes.

Pour 50 g of garlic cloves into 10 liters of water and leave for 3 days. Then add a little liquid soap and spray the apple trees with it. The smell of garlic will repel ticks. Mix 100 g of tar soap with 10 liters of water and treat the apple trees. This product can be used to treat any garden or garden plants every week. Infuse 200 g of onion peels for an hour in 10 liters of water. After this, strain the infusion and squeeze out. Apple trees are also treated with it every week. Hot pepper concentrate also successfully repels spider mites. To prepare it, you need to pour 100 g of hot pepper into a liter of water and bring to a boil. Let the product sit at room temperature for a day. To spray apple trees, a solution is made from this concentrate at the rate of 8 ml of infusion per 1 liter of water. Tobacco infusion is also a good way to protect apple trees from spider mites. To prepare it, you need to infuse 200 g of cheap tobacco in five liters of water for a day. Then bring the infusion to a boil and leave to simmer over low heat for two hours. After cooling, the broth should be filtered, diluted with water 1:1, and 50 g of tar soap dissolved in it. To treat apple trees against spider mites, horseradish infusion is used. To prepare it, you need to chop 400 g of horseradish root and leave it in a bucket of water for 3 hours. Then the infusion is filtered, squeezed out, and the apple trees are sprayed with it. A decoction of fresh henbane has a very effective effect on spider mites.

This product is poisonous, so you need to work with it with extreme caution.

What to do if there are spider aphids in the leaves?

This means that you have two types of insects at the same time : spider mites and aphids .

Aphids reproduce very intensively. Females lay up to 100 larvae at a time. There are several species of aphids, different in color; they suck juice from leaves, branches, and apples using a proboscis.

Then the foliage curls and falls off. In spring, small larvae emerge from aphid eggs. By the end of spring they grow.

Green aphids prefer to breed on young apple trees. Aphids leave a black coating on the tree; it is called sooty fungus. During a season, a female can give birth to up to 10-11 generations. By winter, green aphids lay eggs at the base of the buds.

In summer, apple trees can be treated with tobacco infusion.

Gray aphids prefer mature apple trees. At the same time, the foliage swells, changes color, and then the leaves curl and dry. It is safest to use bioinsecticides, such as verticillin.

For the drug to have a successful effect, the temperature should be +22-240C for 2 days. For spraying, dilute 100-500 ml of verticillin per bucket of water (10 l). Bitoxibacillin and bicol quickly destroy aphids.

After spraying, be sure to clean off the top bark and then paint the tree with whitewash. Then attach hunting belts made of straw or thick paper to the trunk. Aphids usually lay eggs in them, so remove the traps and burn them in late fall.

Mechanical methods

Try collecting cobwebs and caterpillars with your hands. Do this early in the morning, in spring, when the browned young leaves appear. Remove the webs so that the caterpillars remain inside the nests. After eliminating dwellings with insects, burn them immediately.

Using a catch belt against pests

An effective method of control is the use of catching belts, which can be dry, sticky, and poisonous. Read the instructions for making them:

• Sticky - take paper 30 cm wide, attach it to the trunk at a height of about 1 m from the ground, coat it with special glue, tar or resin. To prevent insects from hiding under the bark, carefully coat all cracks with clay in advance. Once a large number of parasites have been collected, remove and burn the belt and attach a new one if necessary.
• Poisonous - buy a special product for killing insects, making sticky traps, generously coat burlap or thick paper 30 cm wide with it, attach it to a tree according to the above instructions.
• Dry - considered the easiest to create. You can make a funnel from thick paper or cardboard: roll a cone of material around the perimeter, secure the top tightly to form a “skirt”; if necessary, coat the attachment point with clay.

Preventive measures

You can protect trees from pests by following simple rules:

• Hollows in trees must be promptly sealed;
• remove weeds around apple trees;
• Apple trees need to be pruned before the growing season;
• fertilize regularly;
• do not plant flowers and cruciferous vegetables around apple trees;
• Any damage to the bark should be treated immediately.

Advice! The natural enemy of spider aphids is ladybugs. You can attract them to your site by planting dill, parsley or caraway seeds next to the apple tree.

In order for apple trees to produce a lot of apples, it is important to regularly inspect the foliage and trunks, and if a web is detected, immediately proceed to fight the pest that left it. Delay can not only significantly reduce the yield, but also completely destroy the tree.

Folk remedies

• Grate a piece of laundry soap , add water and add ash. Soap forms a white film on the leaves, making it difficult for aphids to bite through the leaves, and the ash makes the leaves taste unpleasant.
• Collect 1 kg of nettle , place in warm water, spray the apple tree with this mixture.
• 1 kg of shag into a bucket of hot water. You can boil for 10-15 minutes, then let the mixture sit for 3 days, then strain the infusion and pour in 2 more buckets of water. Then spray the trees.
• Finely chop 200 g of onion and 200 g of onion peel , add a bucket of warm water. Leave for 6 days. Then strain and spray. Do this no more than 3 times in 6 months. This composition will protect the apple tree from aphids, spider mites, and leaf rollers.

Important! Prevention measures:

• do not forget to pull out the weeds;
• cut off the root shoots;
• do not plant cruciferous vegetables and flowers near apple trees;
• feed the apple trees. Read more about fertilizing apple trees and their timing here;
• ladybugs eat aphids, to attract them plant: parsley, caraway seeds, dill;
• prune apple trees before the growing season;
• treat wounds on trees;
• fill up the hollows.

Prevention

If you deal with this problem systematically, aphids or mites will not appear. It is especially important to pay attention to the prevention of seedlings. To prevent pests from appearing on the land, the following measures are necessary:

• be sure to weed the soil - the fewer weeds, the fewer pest larvae;
• basal growth is a threat to the seedling, so it must be cut off immediately;
• flowers should not be planted near the apple tree;
• Feeding the tree will strengthen its defense mechanisms;
• pruning is carried out before the growing season;
• if wounds appear on the bark, they must be treated immediately - use disinfectants;
• If there are hollows in the apple tree, they need to be closed.

Prevention also includes timely pruning of diseased branches and clearing shoots of twisted or dry foliage.

The apple tree is an easy-to-care tree. It requires minimal watering and fertilization. More often a crop suffers from pests than from a lack of moisture or nutrients.

When a cobweb appears on a seedling or mature tree, you need to inspect the branches - there is a high probability that there is a mite, aphid or caterpillar.

Based on external signs, it will be possible to determine the type of pest - then all measures taken to combat parasites will be more effective. Timely prevention will protect the crop in the autumn and spring, when pests become more active.

Spider webs on apple trees: how to fight and what to spray with?

It is very important to understand where the web came from. If you see a web in the form of a mesh, then it is an apple moth. You need to remove the web manually. Be sure to collect and destroy caterpillars, as well as cocoons.

Then spray all the leaves and branches with tobacco dust infusion, so you can even reach those that are very high.

You can still purchase and use entobacterin and dendrobacillin. If you notice egg scales, they also need to be scraped off and burned, like dry branches. Before winter, spray the trees with lime milk.

It kills many insects on contact, forms a cover over eggs, larvae and pupae, prevents caterpillars from moving along the trunk, insulates the bark in winter, reflects the sun's rays, therefore protecting the apple tree from burns, prevents damage to the trunk by rodents, and feeds the tree with calcium.

Important! In early spring, collect and burn cocoons.

Bitoxibacillin

For various apple tree pests: silkworms, spider moths, aphids, leaf rollers, hawthorn, spider mites, American white butterflies, moths, dilute 40-80 g of bitoxybacillin in a bucket of water, use at a rate of 1 liter per 10 m². Allow a week between treatments.

Bicol

Bicol has also been developed; it is effective against apple moth, aphids, hawthorn, American white butterfly, spider mites, and codling moth. It is sprayed during the growing season, 2 applications are made at intervals of a week, the consumption rate is 0.7 kg per hectare. This drug is used against 80 types of pests.

Verticillin

Verticillin is used against whiteflies, spider mites, and aphids. It is created based on the spores of the fungus Verticillium lecanii. Its effect is that the blastospores of the fungus invade the insect, grow there and affect all organs.

Before use, it is recommended to water the apple tree generously. Before use, verticillin is soaked in water for a day, this will speed up the germination of spores.

Entobacterin

To treat apple trees, add 10 g of entobacterin to 1 liter of water. If you use this bioinsecticide against aphids, add 5 g of the composition per 1 liter of water. Dissolve the composition in water at room temperature 6 hours before use, but not less than an hour.

This composition is used against aphids, moths, golden silkworms and other leaf-eating insects. The preparation contains spores of Cereus bacteria. There are approximately 30 billion spores in 1 g of entobacterin.

When sprayed, spores eliminate up to 97% of pests and do not harm beneficial insects. After spraying, entobacterin affects pests for about 1.5 weeks.

Then its effectiveness gradually decreases, and after a month it is zero. Therefore, it is allowed to repeat spraying. But it is recommended to do no more than 2 treatments per season.

The composition works best against pests at an air temperature of +20-30 degrees. At temperatures below 14 degrees, in rainy weather, and even on the first day after it has rained, it is not recommended to use the drug.

Dendrobacillin

Dendrobacillin is a bioinsecticide in the form of a dry powder of a pinkish-gray hue; it does not harm people and warm-blooded animals. Used to eliminate caterpillars, moths, leaf rollers, moths, and silkworms.

30-50 g of powder is poured into a bucket of water. Consumption rate 0.5 g per 1 m². Dendrobacillin can be used even when apple trees are blooming. But it is recommended to spray no more than 2 times per season, observing a weekly interval between sprayings. Can be used 5 days before picking apples.

Chemicals

The drug fufanon
