Description

(54) INSECA ICID COMPOSITION

  one

This invention relates to chemical agents for the control of insecticides, namely, the use of an insecticidal composition based on pyrazoline derivatives.

A insecticidal agent is known, the active principle of which is 1- (4-chlorophenylcarbamoyl) -3- (4-chlorophenyl) -5- (4-chlorophenyl) -d-pyrazoline 1.

However, its activity at low concentrations is insufficient.

The aim of the invention is to find new insecticidal compositions. Possessing high activity.

This is achieved by using, as an active principle, pyrazoline derivatives of the general formula

 With X

In which R and X have the stated values, the forms of use of drugs are common-.

The determination of insecticidal activity is usually carried out using suspensions prepared by introducing an acetone base facT of the amount of 10,000 mpn into water during the preparation. .:: ,, .- Compounds that are loosenable in acetone, finely measure bytes. :. .

Testing conducted on insects | different types .-. .

AU Aedes aegypti L (zHFSHy ygradochny mosquito) ..,

Sample aliquots of 100 ml of domestic water containing 1, 0/3, 0.1, 0.03, etc., respectively, of pyrazolines, substituted in 1,3,4-additions, are injected a ten day solution These samples with larvae are kept at. Yai iM -imbak tcfё s.;

b) Rieris birassicae L (cabbage.; Tse Belokachanna). Cabbage seedlings,

planted in pots, sprayed; suspension of the substance. Suspensions contain 300, 100, 30, 10, 3 million, etc., respectively, of the active compound. The plants are placed in plastic cylinders, in which there are caterpillars of the third age stage, they live during the daily foreign cycle, which is 1.8 and 6 hours, respectively: / - at 24 and respectively and at relative humidity of 60-70 and 80-90%, respectively .

Three replications were performed for each treatment.

After six days, mortality is calculated using the Abotta formula in%.

c) Lepinotasa decemlineata say {Colorado beetle.).

Young potato sprouts, placed in flasks with tap water f, are sprayed with a suspension of the active compound, the suspension contains 300,100, 30, 10, 3, etc., with dissolving active compound. Sprouts are placed in plastic cylinders and injects ten larvae of the third-stage biomass of the larvae. Further experiments are analogous as in the case of cabbage soup. ; The test results are shown in Table. 1-3. The following definitions are accepted: + mortality 90-100%; ± mortality 50-89%; - mortality 0-49% ..
