Description

(54) INSECTICIDE MEANS

In the presence of a solvent or diluent.

Thus, the following compounds of general formula I are obtained, presented in Table. one.

The active ones began, kOHueHTpaiiHH their Duration of assessment and the results are visible from the table. 2

table 2

Experience with Myzus

Forms of application are common; solutions, emulsions, powders, suspensions. They are prepared by methods common in the manufacture of preparative forms of pesticides.

Example 1. Experience with aphids (contact action).

Solvent: 3 wt. including acetone.

Emulsifier: 1 weight. including alkylaryl polyglycol ether.

In order to obtain an active drug, start 1 wt. it is mixed with the indicated amount of solvent and emulsifier and the concentrate is diluted with water to the desired concentration.

The preparation of the current beginning of the crop: zgivayut before the formation of cabbage plants (Brassica oleracea), strongly affected by aphids (Myzus persicae).

After a specified time, the degree of killing is determined. At the same time, 100% means that all the animals have been euthanized, 0% - or only one person has not died.

Example 2. Experiment with larvae of leaf & yes.

Solvent: 3 wt. including acetone.

Emulsifier: 1 weight. including alkylaryl ethers.

To obtain the drug active start 1 wt. it is mixed with the indicated amount of solvent and emulsifier and the concentrate is diluted with water to the desired concentration.

The drug of the beginning of the beginning is sprayed before the formation of kajusta leaves and the larvae of the crap leaves (Phaeilon cochlearial) are planted on them.

After a specified time, the degree of killing is determined. At the same time, 100% means that all larvae are killed, 0% - and one larva is not killed.

The active principles, their concentrations, the duration of the assessment and the results are visible from the table. 3

Table 3 Experience with Phaedch - larvae.

Example 3. Experience with limiting concentration (systemic action through the roots).

Experimental insects. Myzus persieae.

Solvent: 3 wt. h acetone.

Emulsifier: 1 weight. including alkylaryl polyglycol ether.

In order to obtain an active drug, start 1 wt. it is mixed with the indicated amount of solvent and emulsifier and the concentrate is diluted with water to the desired concentration.

The preparation of the active principle is thoroughly mixed with earth. In this case, the decisive factor is only the amount of active principle per volumetric unit of earth, which is expressed in parts per million or mg / l. The cultivated land is poured into pots and planted in cabbage (Brassicu oleraceu). The active principle is perceived by plants from the ground and transmitted to the leaves.

For sbstbmmb1 action through the roots after 7 days, these insect insects are planted. After a further 2 days, an evaluation is made of the counting or determination of dead insects. From the number of dead insects, a systemic action of the active principle is derived. It is 100% if all insects are euthanized, and 0% if as many insects are alive as with the untreated control.

Example 4. Experience with parasitic larvae of flies.

Solvent: 35 wt. including ethnlen-complete glycol monomethyl ether.

Emulsifier: 35 wt. including nonnofenololiglycol ether.

To obtain a drug of the current beginning, 30 wt. the part of the corresponding active substance is mixed with the indicated amount of solvent containing the indicated amount of emulsifier and the concentrate thus obtained is diluted with water to the desired concentration.

Approximately 20 fly larvae (Lucillia cuprina) are planted in a test tube containing approximately 2 cm of horse meat. On this horse meat 0.5 ml of the active ingredient is applied. After 24, the killing degree is determined. At the same time, 100% means that all the larvae are euthanized, and 0% - and one larva is not killed.

Thus, the proposed compounds have good insecticidal activity.
