Problems solved by technology

For example, the suspending agent product produced has a poor suspension rate, which can easily cause uneven spraying and local phytotoxicity of crops. The main reason is that there are different defects in the selection of adjuvants.
[0006] 3), the problem of compounding, through the toxicity test, heat storage stability test and co-toxicity coefficient measurement of several specific proportions disclosed by the above-mentioned several insecticidal compositions, it is found that no obvious additive synergistic effect can be achieved

Abstract

The invention provides compound wettable powder of Pymetrozine and Tsumacide as well as a preparation method thereof, and relates to the field of control technology of rice planthoppers in rice. The powder is prepared from at least 10 parts of Pymetrozine, 20 parts of Tsumacide, 12 parts of fatty alcohol polyoxyethylene ether, 9 parts of phenethyl phenol polyoxyethylene polyoxypropylene ether, and the balance being light calcium carbonate; and the total parts of the powder is 100 parts. Raw materials are mixed, coarse grinding and air-flow pulverizing are carried out in order, mixing is carried out fully, sampling and analysis are carried out, and after the materials are qualified, metering, packaging and warehousing are carried out. The compound wettable powder of Pymetrozine and Tsumacide with concentration of 30% which is compounded by mixing Pymetrozine and Tsumacide according to a ratio 1:2 plays an obvious synergism range, and other preparations which are mixed according to other ratios cannot reach the obvious synergism range.

Description

technical field [0001] The invention relates to the technical field of rice planthopper control, in particular to a wettable powder compounded with pymetrozine and amecarb and a preparation method thereof. Background technique [0002] At present, the existing insecticidal composition for the control of rice planthoppers, for example, the Chinese patent "CN 103053568A" discloses a "compound insecticide for the control of rice planthoppers", the active ingredient of which is pyridaben and Zhongbucarb, wherein the mass ratio of pyridaben and Zhongbucarb is 4:1 to 1:128. In addition, the Chinese patent "CN 102524288 A" discloses an "insecticidal composition for controlling rice planthoppers", the active ingredients include thiacloprid, ethiprole, the weight parts of thiacloprid and ethiprole The ratio is 1:10. [0003] The inventor has verified through long-term experiments that the above-mentioned several insecticidal compositions mainly have the following defects: [0004]...
