Cooperation and application of multiple dosage forms containing pirimiphos-methyl

Abstract

The invention discloses cooperation and an application of multiple dosage forms containing pirimiphos-methyl, and relates to the technical field of insecticide. The cooperation comprises the followingraw materials, by weight: 7-10 parts of pirimiphos-methyl, 14-18 parts of an organic solvent, 5-10 parts of deodorized kerosene, 5-10 parts of a water emulsion additive, 5-8 parts of polycarboxylate,3-7 parts of a microemulsion additive, and 2-6 parts of plant essence. In a process of use, the space water treatment residue is short, and the half life in the environment is short, which greatly reduces the health and safety risks after application. The cooperation of the multiple dosage forms has low toxicity and does not cause toxicity to non-target animals, which improves the safety after use and reduces environmental pollution and toxic and side effects on staff. The cooperation of the multiple dosage forms can play a strong killing effect on pests so as to avoid insecticide resistancecaused by incomplete killing of the pests. During spraying operation, the cooperation of the multiple dosage forms has small stimulation to human respiratory tract, which is beneficial to the improvement of comfort of stall during work.

Description

technical field [0001] The invention relates to the technical field of insecticide, in particular to the compounding of various dosage forms containing pirimiphos-methyl and its application. Background technique [0002] Pirimiphos-methyl, chemical name: O-(2-diethylamino-6-methyl-4-pyrimidinyl) O, O-dimethyl phosphorothioate, which was developed by ICI in 1974 Broad-spectrum, quick-acting organophosphorus insecticide and acaricide, with contact and fumigation effects, good insecticidal effect and long-lasting efficacy. The acute oral LD50 of female rats is 2050 mg / kg, that of male mice is 1180 mg / kg, that of male rabbits is 1150-2300 mg / kg, and that of female guinea pigs is 1000-2000 mg / kg; the acute percutaneous LD50 of rabbits is >2000 mg / kg. It has no irritating effect on skin and eyes, and is recommended by WHO for the prevention and control of sanitary pests. Generally, warehouse insecticide operations are generally divided into physical insecticide and chemical in...

AI Technical Summary

Problems solved by technology

[0005] In the process of using chemical insecticide, the insecticidal solution is diluted with water and sprayed on the floor and corners of the warehouse. The insecticidal solution will become viscous or even precipitated and emulsified after long-term storage, which will affect the use of the staff and is easy to use. Attached to the inner wall of the storage tank, causing waste; in winter, some insecticidal solutions will freeze, and the staff need to thaw them before use, which will affect the work efficiency of the staff; general chemicals with old ingredients The toxicity is high, it will bring different degrees of pollution to food and the environment, and it has great toxic and side effects on humans and animals. After a long time of use, pests will develop drug resistance and affect its insecticidal effect.
