Description

one

This invention relates to means of combating harmful insects, namely insecticidal preparations based on pyrethroids.

The purpose of the invention is to increase the activity of the drug.

Example 1. A preparation of the following composition is prepared, wt%: permethrin 23.0; tetramethrin 2.0; benzyl alcohol 5.0; piperonyl butoxide 5.0 butyloxytoluene 0.1; a mixture of non-ionic and anionic hydrates: kil-C-C, p-aryl sulfonate and polyoxy ethylene triglyceride or polyoxyethylene triglyceride, or polyoxyethylene sorbitan ester (Atlox) 7.5 mixture of saturated aliphatic hydrocarbons CIQ-0.0 57.4,

Example 2. Preparing a preparation containing, in wt.%: Permethrin 1.45; tetramethrin 0.05; benzyl alcohol 0.5; piperonyl butoxide 6.0; propyl gallate 0.1; polyoxyethylene sorbitan monooleate 9.0; ethanol 82.9.

Example 3. Preparing a preparation containing, in wt.%: Permethrin 39.0; tetramethrin 1.0; piperonyl butoxide 3.0; propyl gallate 0.2; sodium salt of aliphatic alcohol sulfonate 14.0; hydrophilic aerosil 35.8; talc 2.0. g

Example 4. Preparing a preparation containing, in wt,%: permethrin 23.5; tetramethrin 1.5; benzyl alcohol 5.0; butyloxytoluene 0.1; piperonyl butoxide 5.0; Atlox 7.5; a mixture of saturated aliphatic hydrocarbons C, pC, j5 50; a mixture of aromatic hydrocarbons With g-C, j 7,4.

Tests of preparations according to examples 1-4 were carried out in comparison with the known agent (preparation A), having the following composition, wt%: permethrin 25.0; piperonyl butoxide 25.0; butyloxytoluene t, 2; Atlox 27.7; benzyl alcohol 5.0; xypol 21.1.

An aqueous emulsion containing 0.5% by weight of the active ingredient was prepared using the composition of Example 1. 1 ml of the resulting emulsion was applied to a glass plate (area 71 cm).

After drying, yellow flour spiders were placed on the glass plate. The insecticidal activity of the preparation was determined after 24 hours. Composition A. was used for comparison. The results are presented in table. one.

The composition according to the winner. 2 was diluted with water and tested with lice when using a concentration of 1.0 0.66 and 0.33 wt%. Mortality was determined after 24 hours.

The results are presented in table 2.

A composition according to Example 3 was tested against a housefly as follows.

An aerosol suspension for spraying containing 0.1% by weight of the active ingredient was prepared from the wettable powder of Example 3 by diluting with water. 1 ml of the suspension was applied to a frosted glass plate (area 71 cm). Then houseflies, stunned by CO, were placed there and covered with Petri grass.

In tab. 3 presents data on the effectiveness of the lesion ().

The results presented in TabLo 1-3 show that preparations containing a mixture of permethrin and tetramethrin show a higher activity compared with a composition containing permethrin as an active compound.

A test of the preparation of example 4 showed that it is not different from the preparation of example 1.
