Anonim

Gardeners use different methods of dealing with bark beetle on the apple tree. It is difficult to save the trees affected by the beetle. The measures are effective at the initial stage. The advanced stages are not amenable to treatment. The apple trees eaten by the beetle are destroyed. To protect the garden from the pest, they resort to the help of folk recipes and chemicals.

Biological characteristics of the bark beetle

Apple bark beetle is a brown (dark brown) color beetle. Body length not more than 4 mm. Adults fly. Rigid elytra are covered with a pattern of dots in the form of parallel stripes.In spring, during the period of mass flowering of fruit trees, insects begin to fly. Females choose a tree for themselves, gnaw moves in it, lay eggs. Larvae emerge from them - white worms with powerful jaws.

The larvae cause the main damage to the tree. Until the next spring, they feed on wood, eat away at the trunk. Before becoming an adult, they pupate. In spring, the development cycle is repeated (adult, egg, larva, pupa, adult).

Species of bark beetles

Bark beetles - a threat to trees, wooden buildings, wooden products. There are 750 species of tree pests in the world. The most common types are:

  1. Sapwood.
  2. Beetle.
  3. Typographer.
  4. Furniture grinder.
  5. Carpenter beetle.
  6. Xylophage.
  7. Shashel.

How dangerous is the bark beetle for an apple orchard?

A small beetle can destroy an entire garden. As a victim, the bark beetle chooses fruit trees, in which, due to improper or thickened planting, the root system is poorly developed, there are mechanical damages on the bark.

There are times when pests attack an absolutely he althy apple tree.

Pest larvae eat wood around the entire circumference of the trunk. The nutrition of the tree worsens, the infection penetrates through numerous passages. Apple trees are dying due to lack of nutrients and fungal diseases.

How to detect the presence of a bark beetle: traces and signs of parasitism

It is necessary to inspect the trunks of apple trees in order to identify the pest in time. Birds flying into the garden can become indicators. It is worth being alert if a woodpecker is operating in it.

Visual signs of life of the apple bark beetle:

  • holes on the surface of the bark;
  • streaks of gum;
  • dust, the structure resembling small sawdust.

The color of the dust determines the degree of damage. Dark - the initial stage. The beetle did not penetrate deep into the tissue of the tree. Light sawdust indicates that the beetles have eaten the wood deeply and it will be difficult to save the apple tree.

Combating parasites with chemicals

First of all, determine the degree of damage to the tree to determine how to deal with the beetle. All methods will be useless if the bark falls off in pieces. If it holds firmly, there are few holes in the trunk, the apple tree can be saved.

Types of funds

Insecticides are used to control the bark beetle.Preference is given to drugs with a wide spectrum of action. They penetrate deep into the tissues of the tree, act on larvae and adults. With the help of chemicals, the crowns of fruit trees are treated before the beginning of the summer of the beetle. Spraying is repeated after 2 weeks. In addition, trees are fed with fertilizers, sanitary pruning is carried out, old stumps are removed, and traps are hung around the garden.

Senezh-Insa

This tool for processing wood and lumber products is produced by the Russian company Senezh. Water concentrate is sold in plastic containers with a volume of 5 l, 60 l. The agent penetrates deep into the tissues of the tree. Processing results:

  • larvae, adult beetles die;
  • bacteria, fungi do not breed;
  • drug repels new pests.

The cost of funds in a canister is about 600 rubles, in a large container - about 4000 rubles.

Clipper

Russian insecticide-acaricide, an analogue of Tolstar, produced in the USA. Purpose of use - pest control on vegetable crops. The product can be used in greenhouses.

Release form - emulsion (concentrate), packing:

  • 5L containers;
  • 1L bottles.

Prophylactic treatment of apple trees is carried out a week before the mass summer of beetles. The protective effect lasts from 20 to 30 days. The processing of trunks (⅔ height) is carried out using an industrial sprayer, a 3% solution is prepared. Clipper destroys larvae and adults of the bark beetle, kills other garden pests.

"Vitalizer HB-101"

Non-toxic drug, all active ingredients of natural origin. The tree is protected from pests and infections by an extract obtained from plants (plantain, pine, cypress, cedar). Packing HB-101: granules, liquid.

Processing scheme:

  • after flowering, the first spraying of the apple tree;
  • 2nd and 3rd treatments are carried out at intervals of 7 days;
  • The solution is prepared from 10 liters of water and 1 ml of the drug.

B-58

German remedy is effective against beetles and larvae. It, getting into the intestines, causes their death. The drug is in the form of a concentrated emulsion.

The product is toxic to humans and bees.

Use it carefully, strictly following the manufacturer's recommendations.

Drug treatment and prevention scheme

To treat apple trees for bark beetle, to carry out preventive treatments, an approximate plan of measures will help.

Beginning of floweringProcessing the crown with "Rich-Micro", trunk - "Bitoxybacillin" Treat the stem with “Confidor Extra” twice (14 days interval)Treat “HB-101” by leaf »When a pest is foundClear movesSyringe with Confidor Maxi solution Smear the holes with pitch Autumn after complete fall of foliageSanitary pruningDestruction of leaves Washing stem, skeletal branches
PeriodSprayerOther ways
Before bud breakFeeding with Diammophoska Sanitary pruning, whitewashing the trunk
Scatter the granules around the trunk circle "HB-101", bury them in the soil

Traps and scarers

Special traps treated with pheromones are sold in gardening stores. They are laid out in the garden in spring until early summer. The smell attracts adults. Beetle traps destroy.

The principle of action of repellers is different. Devices emit a threat smell or a danger signal. By doing this, they force the beetles to look for another habitat.

Injecting the barrel

You can get rid of the beetle in the early stages of the lesion with the help of injection. Solutions of drugs can be injected into the moves:

  • "Antizhuk";
  • "Calypso";
  • "Confidor";
  • Karbofos.

To carry out the work, you need a large syringe. Processing steps:

  1. Preparing the solution.
  2. Introducing fluid into the hole.
  3. Smearing the move with garden pitch.

Folk methods

When a beetle moves, the trunk of an apple tree must be smeared with a mixture of manure and slaked lime in a ratio of 1:1. Dense application guarantees a positive result. Damaged apple trees can be treated with a solution prepared from the following ingredients:

  • water 10 l;
  • liquid soap 2 l;
  • carbolic acid 2 kg.

Stimulation of immunity of apple trees to protect against bark beetle

Weakened apple trees suffer from the bark beetle. The wood of a he althy tree is durable, it is more difficult for beetles to survive and reproduce there. Measures that increase the defenses of apple trees are carried out to prevent the pest.

Activate the immune system, improve the quality of photosynthesis with "HB-101". Prevention steps:

  • in the spring, along the perimeter of the near-trunk circle, embed the granules;
  • after flowering, spray the crown 3 times with a solution (1 ml of product per 10 liters of water), an interval of 7 days.

With the help of "Rich-Micro" fertilizer, tissues are saturated with microelements. Top dressing increases resistance to infections, pests. Apply "Rich-Micro Copper + Zinc + trace elements". When preparing a solution in 10 liters of water, dissolve 1 tbsp. l. fertilizers. Processing is carried out on a sheet 4 times with an interval of 7 days.

To increase stress resistance, apple trees are watered once every 2 weeks with a solution of Gumi-30 Universal. Paste (100 g) is diluted in water (200 ml). The concentrate is used to prepare a working solution. For 10 liters of water add 1 tbsp. l.

It is difficult to save a tree affected by bark beetle. Planned preventive treatments of the garden with modern preparations are the best option for dealing with the beetle.
