Web on an apple tree: causes and remedies

Fruit crops in the garden, including the apple tree, suffer from insect pests. The presence of some can be detected by characteristic signs, such as the web. Pests that leave the web, there are several species, so it is important to identify the insect in time, which will facilitate further struggle with it.

Such garden culture as an apple tree. possesses decorative qualities, in the light of which it is able to decorate and ennoble any territory, garden or cottage, but it also brings delicious and healthy fruits to the owners. However, such a seemingly harmless thing at first glance - the web, which many gardeners, due to inexperience or for other reasons, consider harmless, can spoil the appearance and cause serious harm to the plant.

It is quite possible even for an inexperienced summer resident or gardener to distinguish a spider's web from the one with which a tree is covered during an invasion of pests. In the first case, the networks will be thin and almost invisible, but a dense and white web will indicate the presence of dangerous insects. Among the large number of pests that leave the web on plants, including apple, it is worth highlighting the most common:

• apple spider mite;
• apple moth;
• spider aphid;
• hawthorn and honeydew;
• unpaired and ringed silkworm;
• winter moth;
• ermine mole.

Such a pest as a tick is a very small insect, therefore it is very problematic to establish its presence on the tree with the naked eye. As a rule, the size of adult ticks reaches only 0.5 millimeter, but pests grow and multiply rapidly, therefore the period from laying the female egg until the appearance of an adult insect can be no more than 5-7 days. Despite its small size, the pest is quite dangerous for the apple tree, because it feeds not only on the leaves, but also on the shoots and fruits. Insect sucks the juice from the plant, so the slightest delay in the fight against it will be fraught with the loss of at least half of the crop.

The apple moth is capable of forming a very dense net on plants, using it to replenish the colony of pests with new insects, the larvae also feed on plant sap, therefore, together with the adult moth they harm culture. Caterpillars appear in all gardens without reference to any climate or region, so it is important to process and inspect the apple tree for the presence of such pests.

However, the web on the garden culture can occur not only in spring or summer, quite often there are cases of its detection on apple trees in winter. This is a sign that the hawthorn has settled on the plant. The caterpillars of this species do not stand out long in length; they usually form cocoons and hibernate on a tree, and with the arrival of the first warm days they begin to destroy the plant and lay eggs.

As for the sucker, this insect has wings, thanks to which it is able to appear and begin to multiply in any place. Such a pest is characterized by the appearance of a large cobweb in the branches, it will have white color and good density. The larvae of the nursery feed on apple juices, which are sucked from the buds, leaves, fruits, and flowers of the crop, thereby causing great harm to the apple tree.

In addition, the insect produces rather specific and very sticky decay products, which are able to interconnect the petals on the flowers, foliage and buds. As a result, the formation of fungi resembling a web net occurs in them.

Gray caterpillars on the web, having hairs on the body - this is an unpaired silkworm. The spread of the pest occurs naturally - with the help of gusts of wind, which spreads insects to different plants, where it begins to destroy the culture and actively multiply.

Green caterpillars with light stripes are a winter moth. In the spring, they are able to go deep into the buds of the plant, destroying them from the inside, after which they transfer to the green mass of the plant.

To identify the ermine mole on the garden culture can be on a large white web with black patches, which can envelop the entire crown. It looks like a pest lair. When an individual reincarnates into a butterfly, it lays its eggs in inaccessible parts of the plant, and the caterpillars themselves can hibernate under them. In spring, individuals actively feed on the green mass of the plant. As a result of this destruction, the leaves die off and curl up into a tube, forming the perfect place for a tent of cobwebs.

There are cases when the gardener did not pay enough attention to caring for a plant in the garden, and in such a web about a hundred caterpillars fit right away, which after a short time will turn into butterflies and start laying eggs.

Pest control measures consist in the use of various synthetic and natural poisons, which, if used properly, do not represent harm to humans and animals, but have a detrimental effect on insects. Usually gardeners produce tree spraying several times during the season - in early spring, in summer (in June) and in autumn. But the frequency of spraying can vary depending on the destruction of crops by insects and is not only preventive, but also urgent. To get rid of the web and the pests that form it, special skills and abilities are not required, therefore even an inexperienced gardener can cope with the processing of crops with specialized store preparations and home-made preparations.

Today, there are several highly effective methods for the destruction of pests, one of them is the mechanical processing of horticultural crops. The essence of the work is to remove the spring damaged foliage, which is still young, changed its color to brown. In the phase of the appearance of caterpillars forming a web on the leaves and branches of the apple tree, it is removed from the branches by hand.

If a large number of insect pests are found on a horticultural crop, it should be treated with synthetic preparations. Among the list of funds that are sold in garden stores, it is worthwhile to dwell on the most sought-after gardeners and gardeners.

• Bitoxibacillin. The composition shows high efficiency in the fight against apple moth, aphids and mites. Also, the tool purchased for the destruction of the moth and moth.The tool is implemented in a concentrated form, so before spraying it must be diluted with water according to the proportions specified in the instructions. The frequency of spraying directly depends on the source of infection of the culture, but on average, two treatments at weekly intervals are sufficient.
• "Bicol". The composition has proven itself in the destruction of caterpillars and lepidopteran insects that weave webs on garden crops. However, such chemistry can only be used in the vegetation phase of apple trees, adhering to the instructions for use.
• "Endobacterin". Substances that are part of the preparation are able to cope with almost all insects that harm plants in the garden, especially those that leave webs on plants. Before use, the composition requires dilution in water.
• "Verticillin". This chemical is produced on the basis of spores of fungi that are able to penetrate into the tissues of insects, exterminating them from the inside. Before using the product is soaked in liquid, which promotes the growth of fungi. Fruit plantations before spraying abundantly watered.
• "Dendrabacillin". A granular insect control that is harmless to humans and animals. The composition is dissolved in water, after which they are cultured in the flowering phase. But the tool has limitations regarding the frequency of use - during the year they can spray the plants no more than two times with an interval between treatments of about one week.

If there is no possibility or desire to use synthetic store poisons, no less effective formulations can be used to kill insect pests, which can be prepared independently. Among the popular means of struggle are the following.

• Soap solution with wood ash. The product is non-toxic, as it is prepared from dissolved soap and ash. The first ingredient of the drug will allow the composition after spraying to linger on the plant, forming a film on the green mass and branches. To cope with the frozen composition of the insect will not be able to, in addition, the tool will affect the taste of greenery that will scare away insects.
• Composition based on the shag. Prepare poison according to the following recipe: 1 kilogram of the substance must be poured with a bucket of water and boiled for 5-10 minutes. After that, the solution must be infused for three days at room temperature. After straining the product is diluted with two buckets of water and the processing of garden crops.
• Nettle infusion. Grass needs to be poured over with water at room temperature, then strain and spray sick plants.
• Onion Husk Remedy. For its preparation, you must take the onion and husk and add a bucket of warm water to them. The composition is left to infuse for a week, after this time, the tool must be drained and used for its intended purpose. The drug will be suitable for use for another six months, but for processing crops in the garden it can be used no more than three times per season. Folk remedy demonstrates high efficiency when destroying aphids and mites.

In addition to the above methods of getting rid of insects and cobwebs, also used a biological method. It consists in attracting natural enemies of pests to the plot with fruit plantations. These include feathered and beneficial insects, therefore It is important to maintain a natural biobalance in the garden. To reduce the number of pests can ageniaspis, which lays its eggs in caterpillars, and the latter from this die.

• Weeding and removal of weeds on the plot and in the near-stem circle will make it possible to eliminate the invasion of many pests, and also contribute to the destruction of the larvae that may be in the ground.
• It should be abandoned cultivation near the apple cruciferous cultures. But planting greens or cumin nearby will attract ladybirds, which can destroy aphids.
• Top dressing of fruit plantations will help eliminate insect attacks. It is important to regularly make root feed to the soil was enriched with phosphorus, copper and zinc.
• It is important to regularly prune and form the crown of the culture. It is best to perform these works before the beginning of the vegetation phase. In the old branches most often you can find insect pests, so they must be timely cut.
• Regular inspection of trees will help in time to detect wounds on the trunk or branches, which should be disinfected and healed with garden pitch. Young branches require special attention. If they are found on the branches of the cones of insect eggs, they must be cleaned and destroyed.
• A whitewash of tree trunks with chalk or lime mortar will act as a preventive measure.
