Abstract

The invention provides a water soluble granule of fipronil. It is made from (by wt%) fipronil 0.5-50%, emulsifier 1-30%, dispersing agent 1-10%, wetting agent 1-5%, binder 2-4%, stabilizer 1-3% and the rest is filling material. The invention also provides the preparation method of the soluble granule of fipronil, which comprises kneading, extruding, granulating, vacuum drying at 70°C for 1 hour, screening and packaging. The product of the invention has a high insecticidal effect, is of low cost, is safe and convenient to use and is friendly to environment.

Description

technical field [0001] The invention relates to an insecticidal soluble granule containing fipronil and a preparation method thereof, in particular to an insecticide for plant protection containing the insecticidal soluble granule containing fipronil and a preparation method thereof. Background technique [0002] With the continuous improvement of people's living standards, people's awareness of environmental protection, and our government's emphasis on the ecological environment, the domestic and foreign markets are demanding high-efficiency, low-toxicity, low-residue, and non-toxic There is an increasing demand for environmentally friendly bio-pesticides and chemical pesticides that pollute. [0003] There are many types of insecticides for plant protection, and emulsifiable concentrates and wettable powders are generally used. As we all know, emulsifiable concentrate contains a lot of organic solvents, which are easy to volatilize and catch fire, which are poisonous to h...
