Mechanical preventing and controlling additive for anabasine pesticide and production method thereof

Abstract

The invention discloses a mechanical preventing and controlling additive for anabasine pesticide and a production method thereof. The mechanical preventing and controlling additive is wettable powder with the grain size of 1.0-6.5mu m. The additive is composed of an anabasine pesticide and accessories at the mass ratio of (1-14):20, wherein the accessories comprise the following components in parts by weight: 2-10 parts of sodium dodecyl sulfate, 5-8 parts of a nonionic and anion compound surface active agent, 0.2-3 parts of an antioxidant, 1.3-4 parts of azone, 0.5-10 parts of a dispersing agent, 1-8 parts of sodium carboxymethyl starch and 30-57 parts of padding. According to the invention, the formula and production processes for the wettable powder of the anabasine pesticide are modified, so that the active time and storage time of the wettable powder are prolonged, the whole technology is more suitable for industrial production, and the production cost is optimized to the minimum.

Description

technical field [0001] The invention relates to the technical field of production of pesticides and insecticides, in particular to a mechanized control aid for neonicotinoid pesticides and insecticides. Background technique [0002] Wettable powder is made of pesticide raw materials, inert fillers and a certain amount of additives in proportion and fully mixed and crushed to achieve 98% passing through a 325 mesh sieve, that is, the particle diameter is less than 44 microns, the average particle size is 25 microns, and the wetting time is less than 2 minutes, the suspension rate is more than 60% of the quality standard fine powder. When in use, add water to form a stable suspension, and use a sprayer for spraying. It has good adhesion when sprayed on plants, and the drug effect is better than the powder of the same kind of original medicine. [0003] If the processing quality of wettable powder is poor, the particle size is coarse, and the performance of additives is poor,...

AI Technical Summary

Problems solved by technology

[0003] If the processing quality of wettable powder is poor, the particle size is coarse, and the performance of additives is poor, it is easy to cause product sticking, it is not easy to disperse and suspend in water, or block the nozzle, and it will settle in the sprayer, resulting in uneven spraying and easy to cause partial plant growth. Phytotoxicity, especially after long-term storage of wettable powder, its suspension rate and wettability will decrease

[0004] In recent years, with the rise of aerial spraying, more and more planting areas and crops use aerial spraying. However, due to the small water consumption and high dilution concentration of aerial spraying, many traditional pesticide formulations cannot meet the requirements of aerial spraying. The performance is especially obvious on wettable powder, when it is used for aviation or mechanical spraying, precipitation occurs, nozzles are blocked, etc.
