Effective ways to combat the web on the apple tree

A spider web on an apple tree is a sign that a pest has chosen a tree. Spiders, of course, also weave cobwebs on a tree, but insects that feed on foliage, flowers, and buds of the tree usually leave thick and dense. If you do not deal with them in time, the tree may die.

Who can leave a web on an apple tree?

In order to choose an effective means to kill the pest, it is important to determine who exactly settled on the tree.

Many insects love the apple tree, leaving a web on the leaves:

• spider mite;
• apple moth;
• hawthorn;
• tinker;
• unpaired silkworm;
• spider aphid;
• ringed silkworm;
• winter moth.

Apple moth

This pest is ubiquitous, and the most reliable protection against it is the timely treatment of the fruit tree. If you forget about it, gluttonous caterpillars can ruin most of the crop.

The moth is a small white butterfly. Settling on an apple tree, it lays a lot of eggs in secluded places (near the kidneys, in the places of branching branches). Caterpillars hibernate under the eggs, and with the advent of spring creep out and begin to eat first the buds, then the foliage.

As a result, the leaves begin to dry, and the branches become covered with cobwebs. Each such web can contain up to 70 caterpillars, which subsequently form pupae. In June, butterflies come out of them.

Methods of struggle

If a web is found, it must be collected manually from all those parts of the tree where you can reach.

They fight caterpillars by spraying foliage and branches with solutions: special preparations (Entobacterin, Dendrobacillin) or tobacco infusion made independently.

In the first months of spring, shields are cut and burned. During budding, even before the buds are formed, the apple tree is sprayed with a solution. They prepare it like this - one of the preparations is dissolved in a bucket of water: 4 ml of phytoerm, 10 ml of kemifos, 2 ml of decis or 10 ml of kinmix.

If the insects are too bred, use a solution consisting of a bucket of water and 10 ml of fufanon.

Important! In autumn, you need to carefully inspect the branches of the tree. If eggs are visible on them, they are removed manually, scraping. Damaged branches are cut and burned immediately. Before the onset of cold weather, the apple tree is treated with milk of lime.

Winter moth

If the caterpillars on the apple tree are green in the web, with 1 dark and several light stripes on their sides, then this is a winter moth. In the process of feeding, they make their way inside the kidneys, eat them, and when foliage appears on the apple tree, they switch to it.

Methods of struggle

To protect the tree from this pest, sticky belts are installed below the crown on the tree trunk. trying to get to the branches, insects fall into the trap. When there are enough individuals on the belt, it is removed and burned, and a new one is installed in return.

Unmatched silkworm

Caterpillars of gray color, on the body of which hair bundles are visible, fall on apple trees with gusts of wind.

Methods of struggle

Inspect the trunk in the spring, and the found masonry is scraped off with a knife, and then treated with kerosene.

Apple tinker

Small insects, whose length does not exceed 3 mm, prefer young trees. The difficulty in finding them is that for laying eggs, the pest selects inconspicuous places: folds of bark, for example.

With the advent of spring, larvae hatch from the eggs, which suck the juice from the leaves, buds and flowers of the tree, causing serious damage to the future crop.

In the process of life, insects leave excrement on branches and foliage, creating a favorable environment for the development of a sooty fungus, similar to a web. Because of this, the flowers and leaves begin to blacken first, and then dry.

Methods of struggle

You can cope with the larvae during the vegetative period if you spray the apple tree with infusion of shag, ash, yarrow or soapy water.

Copper shells destroy adult individuals by fumigating trees with tobacco smoke: heaps of straw are laid around the trunk, 2 kg of tobacco dust are poured on top of each, set on fire. Within 2 hours, the piles should burn, producing smoke. Insects will fall into the ground, and carefully dig it.

Ringed silkworm

If the apple tree was covered with a web, on which caterpillars of a dark, almost black color with blue stripes on the back are visible, then a ringed silkworm has wound up on a tree. Caterpillars practically do not show activity during the day, but at night they eat both flowers and foliage.

Methods of struggle

You can prevent the occurrence of a pest if you spray the tree with infusion of milkweed or wormwood even before the buds open. Of the industrial agents, Bitoxibacillin and Lepidocide are effective, but they should only be used after the air temperature warms above 15 ° C.

Spider mite

These insects are so small that it is almost impossible to see them without a magnifying glass: their length reaches a maximum of 0.5 mm. They develop rapidly - from the moment of laying eggs until the appearance of an adult, only a week can pass.

A spider mite damages branches, fruits and leaves.

Red spider mite control methods

If the insects are purple or scarlet, or the cobweb on the leaves of the apple tree is very small, and the inside of the leaves is covered with spots of silver or cream color, the tree is treated with Bicol or Verticillin.

Methods of combating other types of spider mites

In addition to red, there are other varieties of this pest. Insects suck juice from the leaves, and by mid-summer, if nothing is done, the tree may lose half of the leaves.

To prevent this, the apple tree is recommended to be sprayed with a tobacco solution. It is prepared according to this recipe: 1 kg of tobacco dust is poured into a bucket of water. After filtering the infusion, add 10 l of water to it. 50 g of laundry soap are dissolved in this liquid. They process the tree twice, taking a break of 7 days between procedures.

Another effective remedy: 1 kg of dried chamomile flowers is poured with a bucket of water, left overnight. Filter the solution and also spray twice with an interval of 1 week.

Important! Such methods will not help to cope with a large number of ticks. If there are a lot of insects on the tree, chemical preparations will be required.

Nitrofen is a fairly toxic substance, it is impossible to spray it on trees standing closer than 200 m to residential buildings. Bioinsecticides are best used: Bicol or Bitoxabacillin. They are less harmful and can be used in the garden.

Preventative measures

To protect the apple trees from the invasion of the spider mite is quite simple: you need to collect the fallen leaves in a timely manner, cut the branches and clean the trunks of the old bark, burn them.

Spider aphid

As a rule, aphids appear simultaneously with a spider mite. The pest breeds very quickly - the female is able to lay up to 100 larvae at a time.

Green aphid control methods

Green aphids pick young trees. The insect sucks juices from fruits, branches and foliage, using the proboscis, because of which the leaves curl and fall off. Another sign of the presence of green aphids is a black coating on the trunk.

To remove it, apple trees are sprayed with tobacco infusion.

Methods of combating aphid sulfur

Gray settles mainly on adult trees. Symptom of the appearance of the pest is swollen foliage, which changed color. Subsequently, the leaves curl and dry.

Get rid of aphids of this species using bioinsecticides ("Verticillin", for example). Processing is started when the air temperature is set at 22-24 ° C. 100-500 ml of the drug is dissolved in water, sprayed.

After processing the solution, the upper layer of the bark is cleaned off, and the trunk is covered with whitewash. The trap is fixed with special traps - belts constructed of thick paper or straw. In them, the pest lays eggs, and at the end of autumn, the belts are removed and burned.

Folk remedies against the web on the apple tree

How to deal with the web on apple trees, if you do not want to use chemicals in your garden? Turn to folk remedies.

There are several recipes for non-toxic spray solutions:

1. Chips of laundry soap and ash are dissolved in a bucket of water. Thanks to the soap, the solution will cover the leaves with a film, which is difficult to bite through with insects. Ashes will make the foliage taste unpleasant.
2. A bucket of hot water is poured into 1 kg of shag. If desired, the solution is boiled for 10 minutes, and then left for 3 days. After this period, the infusion is filtered, 2 buckets of water are added to it. Sick trees are sprayed with the resulting fluid.
3. 1 kg of nettle is poured with warm water, this infusion is treated with foliage.
4. Take 200 g of onions and husks, add a bucket of warm water to them. Insist 6 days, filter, use as a solution for spraying. Within 6 months, such a liquid can be used on trees no more than 3 times. She will protect them from spider mites, aphids and leafworms.
5. 800 g of dried yarrow pour half a bucket of boiling water, leave for half an hour. Then they add water to a whole bucket, insist 2 days. The solution is treated trees immediately after flowering.

Mechanical ways to combat the web

In the spring, the damaged, brown-colored young foliage is torn off manually. At a time when the caterpillars have already left, they collect a web. It is advisable to do this in the early morning and make sure that the tracks remain on the web. The collected material is immediately burned.

Chemicals

What if the apple tree is on the web and there are too many insects? Alternative methods may not cope with a large number of pests. Then you can use special effective means.

"Bitoxybacillin"

It is used against apple moths, arachnids and ticks, mothssilkworms leaflets and hawthorns. To do this, 40-80 g of the drug is dissolved in a bucket of water, a solution is sprayed with the calculation of 1 liter of liquid per 10 m². Processing is carried out with an interval of 7 days.

"Bicol"

It also destroys most pests weaving a web on an apple tree.

The tool is used only during the growing season, bred according to the instructions.

"Endobacterin"

Spores of the composition are effective against 97% of harmful insects (silkworms, moths, aphids and others), but do not pose a danger to beneficial ones.

10 g of the drug is diluted in 1 liter of water at room temperature, incubated for at least 1 hour, begin processing.

Preventative measures

You can protect trees from pests by following simple rules:

• hollow in the trees must be quickly closed;
• remove weeds around apple trees;
• Before the onset of the growing season, the apple trees must be cut;
• regularly feed;
• do not plant flowers and cruciferous trees around apple trees;
• Any damage to the cortex should be treated immediately.

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

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