Abstract

The invention discloses a method for preparing an assistant for high-efficiency broad-spectrum seed coating agents, which contains 50-70% of an active component and 30-50% of a solvent. The active component consists of a high molecular weight polycarboxylate synergistic dispersant, a phenethylphenol polyoxyethylene ether modifier, branched-chain calcium dodecylbenzene sulfonate and special polyether. The solvent consists of water and microbicides. The final product is made by heating, stirring and stirring at a low speed under heat preservation conditions. The product produced by the method can be applicable to all single and compound seed coating agents, can achieve the dispersing and emulsifying effects and the effect of increasing the suspension rate, can improve the stability of seed coating agents, increase the seed germination rate and the firmness of seed coating agents, and improve the effectiveness and durability. As the assistant using water as solvent instead of organic solvents used in the prior art, the assistant is environment-friendly and harmless to crops.

Description

[0001] Technical field: [0002] The present invention relates to A preparation method of a high-efficiency broad-spectrum seed coating auxiliary agent. Background technique [0003] The characteristic of the seed coating agent is that it swells and breathes in the soil without being dissolved, so that the seeds can germinate normally and release pesticides and fertilizers slowly. It can kill underground pests, prevent and control seed germs, increase the germination rate of seeds, and reduce the amount of seeds used Improved crop varieties. The seed coating agent is close to the seeds, with concentrated medicinal power and high utilization rate, so it saves medicine, labor, and seeds compared with spraying, soil treatment, poisonous soil and other spraying methods; Harm natural enemies, safe to use; after the seed coating agent coats the seeds, the pesticide is generally not easy to spread quickly to the surrounding area, and is not affected by the sun, rain and high temp...
