Description

BASIC Auth. EU- No. 122850 describes a preparation consisting of hexachloran, nicotine, turpentine, transformer oil and an emulsifier, which is acaricidal and insecticidal liquid of a dense consistency with the smell of needles and used in veterinary practice to combat blood-sucking mites, insects, gadfly and other parasitic animal diseases.

New in the proposed method is the use of this drug to combat plant pests.

The preparation consists of hexachlorane enriched with gamma isomer, nicotine salts, turpentine, transformer oil and emulsifier, forms a stable emulsion with water that does not exfoliate and does not lose its insecticidal properties for a long time.

For production, the components are taken in the appropriate proportions and in the following order: turpentine 45 / o, spindle or transformer oil 28.4%, soap 7, water 2.3%, OD 5Vo, hexo-chloro 8, G1 / o and nicotine (raw) 3.6%.

In a mixture of turpentine and oil, hexochlorane is dissolved in a water bath at 70-80 °. Then a pre-prepared emulsifier (soap + OP-water) is added and everything is stirred in the form of heat. Nicotine is added to the mixture. The drug is used as a chemical precursor for controlling plant pests, in water-oil emulsions from 0.01% to 0.3% of the concentration on gamma isomer of hexachloran and is not toxic to plants. The use of the drug in a production environment showed lOOVo-ing death of plant pests.

Subject invention

A method for controlling plant pests by treating them with dohimicate solutions, characterized in that an aqueous emulsion of a desired concentration of acaricidal and insecticidal liquids prepared by the method of Avto122850 is used as a doxidate.
