Abstract

The present invention relates to the application of azadirachtin in the preparation of seed coatings. The application of azadirachtin in seed coatings for the first time overcomes its photosensitivity weakness and is applied to soil, and its insecticidal effect is not washed by light, evaporation and rain. The influence of azadirachtin can protect the maximum amount of drug on the target body, thereby enhancing the stability of azadirachtin, prolonging the effective period, giving full play to the insecticidal and sterilizing functions of azadirachtin, and controlling various seed pests and diseases. At the same time, for the first time, sulfur powder is used as the active ingredient of the seed coating agent to give full play to its protective bactericidal and insecticidal properties and reduce the cost of the seed coating agent. In particular, it has a high co-toxicity coefficient with azadirachtin, which solves the defects that sulfur is easy to precipitate and agglomerate, and also ensures that azadirachtin has better stability.

Description

1. Technical field [0001] The invention relates to the new application of azadirachtin in the field of insecticides, in particular to the application of azadirachtin in seed coatings. 2. Background technology [0002] Azadirachtin (Azadirachtin Az) is currently recognized as a non-toxic, photosensitive plant insecticide. It is a highly oxidized citrin with many similar functional groups. AZ-A isolated from neem seeds Up to AZ-G7 kinds of active chemicals, of which A is the main insecticidal ingredient. Azadirachtin and its preparations have various effects on insects, such as antifeedant inhibition, growth regulation, and sterilization. Such as Chinese patent application 99116209 "Azadirachtin mixed pesticide preparation and preparation method thereof" discloses a high-efficiency, low toxicity, non-polluting insecticide; It is also a botanical pesticide. Azadirachtin is currently recognized as an ideal insecticide in the world, but azadirachtin has the weakness of being e...
