Problems solved by technology

Due to the drift of the pesticide powder and the large amount of flammable organic solvents harmful to humans, animals and the environment in the pesticide emulsifiable concentrate, such as benzene, toluene, xylene, etc., it is very easy to make the powder in the powder during production, storage and use. and the organic solvent in the emulsifiable concentrate is distributed into the atmosphere and absorbed by the human body, which is prone to poisoning or drug injury, and there are potential safety hazards and serious environmental pollution
Moreover, due to the long-term use of emulsifiable oils and powders, pests develop resistance, pollute the soil, and destroy ecology, making their efficacy greatly reduced.
[0003] As a new type of effective insecticide, diazinon has positive efficacy, but it is currently used as an emulsifiable concentrate, which inevitably has the above-mentioned shortcomings

Abstract

An insecticide in the form of micro-emulsion, aquatic emulsion, or water-dispersible particle for preventing and eliminating the pests of cotton and paddy rice is characterized by that its active component is diazinon.

Description

technical field [0001] The invention relates to a pesticide, in particular to a new dosage form of an organophosphorus pesticide-diazinon pesticide. Background technique [0002] For a long time, most of the pesticides in our country are used in the form of powder or emulsifiable concentrate. Due to the drift of the pesticide powder and the large amount of flammable organic solvents harmful to humans, animals and the environment in the pesticide emulsifiable concentrate, such as benzene, toluene, xylene, etc., it is very easy to make the powder in the powder during production, storage and use. And the organic solvent in the emulsifiable concentrate is emitted into the atmosphere and absorbed by the human body, which is prone to poisoning or phytotoxicity, and has potential safety hazards and serious environmental pollution. Moreover, due to the long-term use of emulsifiable concentrates and powders, pests develop drug resistance, pollute the soil, destroy ecology, and great...
