Problems solved by technology

For example, the prepared wettable powder is not easy to disperse and suspend in water, or block the nozzle, and cause precipitation in the sprayer, resulting in uneven spraying
[0006] 3), the problem of compounding, through the toxicity test, thermal storage stability test and the determination of the mixed co-toxicity coefficient of the several specific proportions disclosed by the above-mentioned several insecticides, it is found that no obvious synergistic effect can be achieved

Abstract

The invention discloses dinotefuran and thiamethoxam compounded wettable powder and a preparation method thereof and relates to the technical field of prevention and control of thrips of ornamental flowers and plants. The dinotefuran and thiamethoxam compounded wettable powder is prepared with 12 parts of dinotefuran, 48 parts of thiamethoxam, 7.5 parts of fatty alcohol polyoxyethylene ether, 7.5 parts of phenethyl phenol polyoxyethylene ether and 25 parts of light calcium carbonate. The preparation method includes: mixing raw materials; sequentially performing rough smashing and airflow smashing; mixing sufficiently, sampling, and analyzing; metering, packaging and warehousing after being qualified. The dinotefuran and thiamethoxam compounded wettable powder is reasonable in dosage form designing, has good effect on preventing and controlling the thrips of the ornamental flowers and plants and can realize obvious synergistic effect of dinotefuran and thiamethoxam.

Description

technical field [0001] The invention relates to the technical field of ornamental flower thrips control, in particular to a wettable powder compounded with dinotefuran and thiamethoxam and a preparation method thereof. Background technique [0002] At present, the existing insecticides used for the control of thrips in ornamental flowers, for example, the Chinese patent "CN 104886114A" discloses a "low-capacity spray containing thiamethoxam and dinotefuran", which uses a weight ratio of 10- 50: 1-20 thiamethoxam and dinotefuran for compounding. Another Chinese patent "CN 103053586A" discloses a "synergistic insecticidal composition containing dinotefuran and thiamethoxam and its application". Compounded with insecticide. [0003] The inventor has verified through long-term experiments that the above-mentioned several insecticides mainly have the following defects: [0004] 1), by testing several specific proportions disclosed by the above-mentioned several insecticides, i...
