Medvedka is a malicious pest that lives in the ground and is highly fertile. The female is able to lay up to 400 eggs at a time.

The bear population can cause very significant damage most garden plants, flowers and their bulbs, strawberry bushes and strawberries.

She not only eats the plants, but also cuts off the thin stems of the seedlings with her claws.

In beds with only planted seeds, the pest breaks through numerous passages, preventing their germination. To get rid of the bear radically, there is a large assortment of chemical insecticides that destroy both adults and their offspring.

We have selected list of the most effective and popular means of fighting a bearthat are guaranteed to save your garden from adversity without damaging the plants.

Ammonia

Many experienced gardeners fight the bear with the help of ammonia (ammonia water). In addition, ammonia is an excellent nitrogenous fertilizer.

Release form

Aqueous solution in plastic or glass bottles.

Chemical composition

Ammonium hydroxide - 30% concentration.

Mechanism of action

Ammonia is a remedy for a bear, which has a pungent unpleasant odor, which repels harmful insects.

Duration of action

Very short, the smell disappears quickly. Therefore, application is necessary at least once a week.

Compatibility with other drugs

Ammonia against the bear should not be combined with baits that attract the bear with their smell.

When to apply?

During any growing season when watering.

Mode of application

Introduce 3-4 dessert spoons of ammonia water into a bucket of water, stir well and water the plants under the root.

Toxicity

The drug is very toxic to humans and all warm-blooded animals - hazard class 2.

Terradox

This remedy against the bear has a very wide range of effects on most pests living in the ground.

A reliable and proven drug that is guaranteed to destroy the bear.

Release form

Granules in a waterproof bag. Packing 100g.

Chemical composition

The main substance is diazinon at a concentration of 40g / l.

Mechanism of action

Neurotoxic properties lead to paralysis of the limbs in the bear. This is due to a blockage of the enzyme cholinesteraseinvolved in the transmission of impulses of the nervous system.

The enzyme should cause hydrolysis of free acetylcholine, which instead begins to accumulate in the synaptic opening, interfering with the passage of impulses.

Methods of entering the body - intestinal, systemic and contact. If you constantly use this drug, you can get a bear, developed resistance to its effects.


Duration of action

The period of plant protection from the bear lasts at least 13-15 days. At this time, diazinon gradually enters the plant through the root system.

Compatibility with other drugs

Diazinon works well with herbicides and fungicides. Water emulsion is actively used in tank mixes.

When to apply?

It is preferable to apply the insecticide before the rain. Other weather conditions do not play a special role... The granules are applied when planting plants and then during any growing season.

The exceptions are strawberries and strawberries - the drug for its protection is laid in the soil after harvesting.

Mode of application

Terradox granules are intended for introduction into the ground. Directly in the beds or aisles, pits are made or grooves with a depth of 2-4 cm, in which insecticidal granules are laids.

For 10 square meters of area 20-25 g of the drug is consumed. During the season, you can do 2 treatments with a break of 2 months.

Toxicity

Terradox is classified as hazard class 3 as a drug with low toxicity to animals, bees and humans.

Vofatox

Combined insectoacaricide used to kill ground pests. Has a very wide range of effects.

Release form

Wetting powder packed in 100 and 20 ml vials and 5 ml ampoules.

Chemical composition

bifenthrin 100 g / l
imidacloprid 100 g / l

Mechanism of action

Bifenthrin, like other pyrethroids, disrupts the exchange of sodium and calcium. Imidacloprid slows down the opening of sodium channels and inhibits the activity of enzymes involved in the transmission of impulses along the nerves.

Thus, the normal functioning of the nervous system is disrupted from two sides at once. The insect has strong overexcitation, convulsions and convulsions, turning into paralysis and, as a result, death.

The drug is systemic, enters the body by contact and intestinal routes... The likelihood of developing resistance is very small.

Duration of action

Activity is guaranteed to last for 15-18 days. The complete disintegration of the agent occurs after 45 days.

Compatibility with other drugs

Combines with fungicidal agents.

When to apply?

Climatic conditions do not affect the effectiveness of the drug. The use of the product after rain is encouraged.

How to prepare the bait?

The basis is taken boiled groats - pearl barley, peas, corn, millet. The porridge should be crumbly and well-cooked.

Vofatox (20 ml) is poured with a small amount of water (100 ml) and stir until the powder is completely dissolved. The solution is filled with 1 kg of porridge and mixed well. For half an hour, the mixture is left alone to infuse.

Immediately before use, 40-50 ml of overcooked vegetable oil is added to the bait and mixed again. You can store the mixture in a cold place for no more than 3 days.

Mode of application

The prepared bait is laid out around the planted seedlings on moist soil and covered with a small layer of soil so as not to attract birds.

Chemical composition

  • Boric acid;
  • Kerosene;
  • Groats;
  • Sugar;
  • Sunflower oil;

Mechanism of action

Boric acid, once it enters the digestive system, destroys the intestinal wall and water balance, causing dehydration. Kerosene inhibits respiratory function.

Duration of action

The drug works for 10-14 days.

Compatibility with other drugs

It goes well with most of the known drugs.

When to apply?

The first treatment should begin before planting the plants and sowing seeds in the beds. Repeated - as needed, but especially during the breeding of the bear. Weather conditions are not important.

Duration of action

Death occurs 3 hours after the drug enters the bear's body. The duration of the toxic activity is up to 20 days after placement in the ground.

Compatibility with other drugs

Malathion, among other organophosphates, combines well with most of the known insecticides and fungicides.

Not so long ago, inquisitive gardeners discovered that the Regent drug, which intended for the destruction of Colorado beetles, is also effective against a bear.

The bait is prepared from boiled cereals (1-1, kg), which is impregnated with the contents of one Regent package. 3-4 tablespoons of sunflower oil are added to the mixture, all this is thoroughly mixed and laid out in the beds, lightly sprinkling with soil.
