Content
Vallar for cockchafer larvae is one of the most effective remedies. Many insecticides only get rid of adult insects. Most often, they have no effect on beetle larvae. Therefore, the drug spread quite quickly among summer residents. It is used for processing fruit crops, berries (including strawberries), saplings and seedlings of various trees - deciduous, coniferous. It is fast and highly efficient.
Purpose
Vallar is a chemical insecticide that is used for the prevention and control of the following pests:
- larvae of the May beetle and other varieties of beetles;
- wireworms;
- false wireworms.
The product is used to treat different crops:
- saplings and seedlings of conifers, deciduous trees;
- ornamental plants;
- fruit trees - apple, pear, plum and others.
Composition and release form
The active ingredient in Vallar is diazinon. It is an organic nitrogen-containing compound consisting of nitrogen, phosphorus and sulfur. Empirical formula for compound C12H21N2O3PS.Belongs to the class of organophosphorus compounds (OPS).
It comes in the form of granules that dissolve well in water at room temperature. The concentration of the active substance is 40 g per 1 kg. The product is packaged in bags. The manufacturer and registrant of the insecticide Vallar for the cockchafer is the company CJSC "August" (Russia, Moscow).
The drug is sold in convenient packages
Operating principle
According to the principle of action, the insecticide Vallar belongs to three categories:
- Intestinal - penetrates the intestines of the insect (along with the juice of the plant being eaten) and destroys it.
- Contact – also penetrates through direct contact with the integument of the body and limbs.
- Systemic - absorbed by plant tissues and then moves through the vessels. Due to this, chafer beetles feeding on juices receive a toxin and die en masse.
In terms of its effect on pests, diazinon is classified as a nerve poison. It acts similarly not only on arthropods, but also on warm-blooded animals. The substance inhibits vital esterase enzymes that transmit nerve impulses. This leads to the accumulation of acetylcholine, the concentration of which reaches critical values, which leads to muscle cramps and ultimately to paralysis. As a result, after 2-3 days, the complete death of the larvae of cockchafers and other beetles occurs (the effect is noticeable already in the first day).
After treatment with Vallar, plants are reliably protected from pests for 30-40 days. There is no waiting period, so the harvest can be harvested within a few days. It is advisable to wait at least 4-5 days from the moment of the last treatment.

How to use Vallar against cockchafer larvae
The instructions for using Vallar are quite simple. It is used in the form of a “chatterbox” - an aqueous extract. You need to do this:
- Wear gloves.
- Measure out the required amount of the drug (8 g per 1 liter of “chatterbox”).
- Pour a glass of water (200 ml) into a container.
- Dissolve the granules and stir.
- Add enough soil to form a thick mass.
- Bring to a total volume of 1 liter, stirring continuously.
- If necessary, add a little soil to form a paste.
- Place seedlings with an open root system for several hours.
- The next day, plant them in the ground.
Vallar against cockchafers is also used 25-30 days after planting seedlings or saplings in the ground. The granules are scattered superficially, focusing on a consumption rate of 5 g per 1 m2. After this, dig in a little so that the granules move into the surface layer of soil. During the season, it is enough to carry out 1-2 treatments (first in the form of a “chatter”, then - direct embedding of granules into the ground).
To completely destroy the larvae of cockchafers, it is enough to carry out two treatments.
Compatibility with other drugs
It is not recommended to mix Vallar with other drugs. It is better to treat with insecticides at intervals of 3-5 days or more.
Therefore, it is recommended to use it in alternation with other insecticides.
Judging by the reviews, the insecticide can be used to protect strawberries from May beetle larvae
