Chlorbenzuron water-dispersing granules preparation

Abstract

The invention relates to an agricultural pesticide, which utilizes dimilin as an effective component, and a water dispersed granulars agent prepared from the pesticide can be used for preventing cabbage worms of brassicaceous vegetable. The components of the pesticide comprises the dimilin, aids and stuffing; the aids are a dispersant, a wetting agent, a disintegrating agent and an adhesive; the stuffing is one or more than two mixing stuffing of white carbon, argil, bentonite, light calcium carbonate, attapulgite earth, talcum powder and kaolin,. The invention can be used for solving the problem of a missible oil microbial inoculum of low glitter, low storage and transport safety, poor worm killing effect, high cost and environment pollution. The invention can be quickly disintegrated and dispersed, and has a stable dispersion system; the preparations does not result in dust flying during the production, using and packing processes, thus being safe to the operator and free of environmental pollution; compared with the wettable powder, the invention has the advantages of large density, small size, greatly reduced packing and storage and transport expenses, convenient recovery of the packing materials, and prevention effect as high as 85.76 to 98.56 percent, which is 1.5 times than that of the prior art.
