Dry pesticide suspension agent as well as preparation and application methods thereof

Abstract

The invention discloses a dry pesticide suspension agent. The dry pesticide suspension agent is prepared from following components in percentage by mass: 50% to 90% of tricyclazole, 1% to 5% of wetting agent, 1% to 15% of dispersing agent, 1% to 10% of disintegrant, 1% to 5% of binder, 1% to 8% of fly defense special additives, 0% to 1% of defoamer, and the balance of filler. The dry pesticide suspension agent disclosed by the invention solves a problem that a high-content suspension agent is prone to crystallization and sedimentation during a normal storage process, avoids the defects of dustflying and long disintegration time in a dry granulation process, and has the advantages of small particle size, good dispersion, high suspension rate and the like. In the fly-proof application, compared with water-dispersible granules, the dry pesticide suspension agent has the advantages of anti-volatile, anti-drift, and no plugging effects. The adhesion of a drug dropping on the surface of a crop is good, and the application times are reduced. Compared with other granulation processes, a preparation process of the dry pesticide suspension agent disclosed by the invention has the advantagesthat continuous production is easy to realize and environmental protection is realized.

Description

technical field [0001] The invention relates to a pesticide dry suspension concentrate and belongs to the field of pesticide preparations. Background technique [0002] In the current and future agricultural production in my country, labor shortage has become one of the key factors restricting agricultural development. The use of drones for plant protection spraying has significant advantages such as accurate spraying, high operating efficiency, wide application range, less labor, water saving and chemical saving. [0003] With the rapid development of the agricultural plant protection UAV flying defense business, nearly ten million acres of farmland have been sprayed with plant protection UAVs every year. Mechanization and automation of pesticide application has played an important role, which can effectively save costs and improve the efficiency of prevention and control. [0004] At present, the total amount of dilution agent sprayed by conventional plant protection dro...

Problems solved by technology

However, due to the limitations of the physical and chemical properties of the active ingredients of some pesticides, it is difficult to prepare liquid preparations, and the existing solid dosage forms such as water-dispersible granules and wettable powders have very poor dispersion uniformity when diluted 30-50 times, and drug liquid separation is easy to occur. Problems such as layering, sedimentation, and clogged nozzles make it difficult to apply to low-volume or ultra-low-volume sprays
