Abstract

A pesticide additive of the present invention, by selecting a suitable solvent, cosolvent, viscosity reducer, penetrant type and ratio, the additive system has reasonable volatility, density, flash point, viscosity, and adhesion, and can A certain amount of pesticide active ingredients are fully dissolved, and the preparations of insecticides, fungicides, and plant growth regulators formulated with this adjuvant can be directly used in ultra-low volume without any change or addition of additives. Spraying or spraying with a hot fog machine is used for preventing and controlling pests and diseases on crops or promoting effective tillering of crops; meanwhile, a preparation method of the pesticide adjuvant is also disclosed.

Description

technical field [0001] The invention belongs to the field of pesticides, and relates to a pesticide adjuvant suitable for ultra-low-capacity spraying by an ultra-low-capacity sprayer and a preparation method thereof. Background technique [0002] Among the existing common dosage forms such as: emulsifiable concentrate, microemulsion, water emulsion, suspension concentrate, water dispersible granule, wettable powder, it needs to be sprayed with water to achieve an effective insecticidal effect. The dosage form that needs to be sprayed with water requires a large amount of fresh water. The problem of consuming a large amount of fresh water is particularly prominent in water-scarce areas or large-scale unified prevention and control (an important means of integrated pest management (IPM). [0003] In the study of dosage forms to reduce fresh water consumption, Ultra-low volume Concentrate (hereinafter referred to as ULV) is one of the choices, it is a special oil agent, which u...
