Dinotefuran and monosultap compound wettable powder and preparation method thereof

Abstract

The invention provides dinotefuran and monosultap compound wettable powder and a preparation method thereof, relating to the technical field of insecticides. The dinotefuran and monosultap compound wettable powder is prepared from the following components in parts by weight: 16 parts of dinotefuran, 64 parts of monosultap, 3 parts of primary alcohol ethoxylate, 3 parts of phenethylphenol polyoxyethylene polyoxypropylene ester and 14 parts of light-weight calcium carbonate. The preparation method comprises the following steps: mixing the raw materials; sequentially carrying out rough crushing and airflow crushing on the raw materials; sufficiently mixing the raw materials, sampling and analyzing, and metering after the product is qualified; and packaging and storing. The dinotefuran and monosultap compound wettable powder is suitable for preventing and treating ornamental flower thrips and rice-stem borers, and has a good pesticide effect, and has a very good popularization and application value in production. The dinotefuran and monosultap compound wettable powder is safe to flowers and rice under a testing dosage, has no phytotoxicity and basically has no influence on beneficial organisms including natural enemies and the like.

Description

technical field [0001] The invention relates to the technical field of insecticides, in particular to a wettable powder compounded with dinotefuran and monosultap and a preparation method thereof. Background technique [0002] At present, the existing insecticide products used to prevent and control insect pests of rice crops, for example, the Chinese patent "CN 101971856 A" discloses an "insecticidal composition containing dinotefuran and monosultap", in which the effective active ingredient It is dinotefuran and monosultap, and the ratio of the two is 1-10:1-80. Another Chinese patent "CN 103798276 A" discloses a "insecticidal compound containing dinotefuran and monosultap", wherein the effective active ingredients are dinotefuran and monosultap, and the ratio of the two is 1 :120~40:1. [0003] The inventor has verified through long-term experiments that the above-mentioned several insecticide compositions mainly have the following defects: [0004] 1), by testing seve...

AI Technical Summary

Problems solved by technology

For example, the prepared wettable powder is easy to cause product sticking, is not easy to disperse and suspend in water, or clogs the nozzle, and precipitates in the sprayer, resulting in uneven spraying and easy to cause phytotoxicity in wheat stems and leaves. The reason is that there are different defects in the selection of additives and fillers

[0006] 3), compounding problem, by carrying out toxicity test, thermal storage stability test and mixing co-toxicity coefficient measurement to several specific proportions disclosed by the above-mentioned several insecticide compositions, it is found that thrips for ornamental flowers, rice The control of Chilo borer can not achieve obvious synergistic effect
