专利说明:

The invention relates to chemical plant protection products, in particular, to an insecticidal composition based on an active substance. A commercial drug is known - dursban (O, 0-diethyl-0-3,5,6-trichloropyril dithiophosphate), which is used as an insecticide 1. An insecticide is known, the beginning of which is 2- (nitromethylene) pyrrolidine 2. However, the known Compounds are not active enough. The purpose of the invention is to find a new insecticidal composition having a good insecticidal activity. The goal is achieved by using an insecticidal composition, the active substance of which is 2- (nitromethylene) -p-peridin of the general formula where n is 0,1,2; X - fluorine, chlorine, bromine, iodine, methyl, methylthio, ethylthio, pro Piltio, methylsulfinyl, methylsulfonyl. Y is hydrogen; chlorine, bromine, nitro, R — C —C — alkyl, allyl, methoxymethyl, hydrogen or its complex compound with methanesulfonic or ethanesulfonic acid, where is hydrogen, p-0. The content of the active substance in the composition is O, 000150 wt.%, The rest is additive. Compounds of formula 1, where R is hydrogen, are prepared analogously to the preparation of 2- (nitromethylene) -pyrrolidones L2J f; however, valerolactams (2-piperidones) are used as starting materials, Compounds of formula 1, where R has a different meaning, or hydrogen are also derived from valerolactomas (2 Piperidones): Lachts (2-piperidone) are treated with dialkyl sulfate or trialkyl-oxonium-fluoroborate, then treated with alkoxide to obtain the corresponding lactam acetal (1-alkyl-2, 2-di -. (RO) piperidine, 2-RO- 3,4,5,6-tetrahydropyridine, which is then processed nitromethane or 1-nitroalkane are prepared. Thus, the following compounds of formula I are obtained

The use of compositions is usual: solutions, dispersions, dusts, aerosols. They are prepared by methods common in the manufacture of preparative forms of pesticides.
Example. Determination of insecticidal activity.
Insecticidal activity is determined using tests that enable the LC indicator to be determined (the dosage in grams of the test compound per 100 millimeters of solvent required as a solution or suspension when applied by spraying to kill 50% of experimental insects) of the compounds of the invention under consideration, in relation to different types of insects, the results are summarized in table 2. A liquid carrier, using AEMELM to make a solution or suspension, is a mixture consisting of 2 parts by volume of acetone, 8 parts by volume of water and 0.05% by weight. parts wetting means Atlox.
PRI me R 2.
The potential of test compounds for rapid motility loss was determined by observing house flies during the initial test, the results are shown in Table 2. The test compound is considered to be an agent effective in terms of rapid loss of mobility, if within 30 minutes 80% of the flies lose mobility, with coititration of 0.5% by weight (volumetric of the solution used in the molten form. Compounds 1, 5, b, 7, 11, 12, 14, 16, 17 meet these requirements.

Insecticidal activity is determined by means of tests that enable the ICjo value to be determined (the dosage in grams of the test compound per 100 ml of diluent required — if used for spraying as a solution or suspension — to kill 50% of the experimental insects) the case of compounds with respect to insect raids; The liquid carrier used to prepare the solution or suspension consisted of a mixture of 2 parts by volume of acetone, 8 parts by volume of water and 0.05 parts by weight of the wetting agent Atlox. The results are summarized in table 3.
PRI me R 4.
The potential of test compounds for rapid loss of mobility is determined by observing home flies during the initial test, the results of which are summarized in Table 3. The test compound is considered a means of ensuring rapid loss of mobility, if within 30 minutes 80% of flies lose mobility at a concentration of 0% by weight (% by volume from the solution used in a sprayed form).
Compounds 10, 19, 21, 22, 23, 24 meet these requirements.
PRI me R 5.
Compounds tested according to example 4 are tested at a dosage of 0.1 vol.% (Bulk in the composition of the solution used for spray application). Any such compound that causes a loss of mobility in 50% of the flies within 30 minutes is additionally tested, but using the same technique for determining the value of the indicator (the number of minutes required to ensure the immobility of 50% of the flies when dosing the solution used for distribution , 1 wt./about. The KTjj values found are summarized in Table 4.
PRI me R 6.
Comparative tests are carried out using as a comparison the known compounds - the commercial preparation Dursban 1 and 2 - (nitromethylene) -pyrrolidine 2.
The test objects are the cotton worm and the Tobacco Budv / o rm larva.
The toxicity index is determined and b D 50.
The results are presented in table.5.
The table shows that the proposed compound is much more toxic with respect to the insects under test.
Thus, the proposed compounds exhibit good insecticidal activity.
