Problems solved by technology

The above existing technologies all have defects to varying degrees, which are mainly manifested in 1) the production of water-based suspending agent seed coatings has problems such as large volume, transportation volume and packaging volume, poor storage stability of the preparations, and high risk of poisoning during use.
② Isofenphos-methyl, phorate or methyl parathion are high and highly toxic pesticides, which are easy to pollute the environment and cause human and animal poisoning when used in seed coating

Abstract

The invention relates to a powdery seed coating agent for the prevention and cure of underground pests of sprout period corns and soybeans containing chlorpyrifos, wherein the agent comprises 1-50 wt% of chlorpyrifos, 1-50 wt% of bactericidal agent, 1-20% of surface active agent, 1-20% of binding agent and film former, 0.1-2% of aposematic coloration and right amount of extender.

Description

technical field [0001] The invention relates to a powder seed coating agent for preventing and controlling underground pests in seedling stages of corn and soybean with chlorpyrifos as an active ingredient. More specifically, it is a powder with good environmental compatibility processed by the active ingredient of organophosphorus pesticide, chlorpyrifos, combined with screened fungicides, surfactants, binders and film-forming agents, warning colors and appropriate fillers. Seed coating dosage form. Background technique [0002] Seed pesticide treatment is one of the most economical and convenient methods in the control of crop diseases and insect pests, and it is also an important measure for efficient and precise pesticide application. For a long time, the method of seed treatment basically is to use powder, wettable powder, water, emulsifiable concentrate etc. to carry out seed dressing, soaking or stuffing, and apply water-based flowable su...
