Pyraclostrobin and trifloxystrobin compound suspending agent and preparation method thereof

Abstract

A pyraclostrobin and trifloxystrobin compound suspension and a preparation method thereof relate to the technical field of banana scab prevention and control. At least 10 parts of pyraclostrobin, 30 parts of trifloxystrobin, 3 parts of fatty alcohol polyoxyethylene ether, 3 parts of styrylphenol polyoxyethylene ether, 0.3 part of xanthan gum, 0.4 part of sodium benzoate, defoamer 0.3 parts and make up to 100 parts of deionized water. All the raw materials are pumped into the preparation tank for mixing and stirring, and then firstly ground by a colloid mill, then finely ground by a sand mill, sampled and analyzed, filtered, measured, packaged, and put into storage after passing the test. The present invention mixes the compounded 40% pyraclostrobin and trifloxystrobin compound suspending agent in a ratio of 1:3, which can play an obvious synergistic effect on the prevention and treatment of banana scab, while other ratios Mixed preparations cannot reach the range of obvious synergistic effects.

Description

technical field [0001] The invention relates to the technical field of prevention and treatment of banana scab, in particular to a compound suspending agent of pyraclostrobin and trifloxystrobin and a preparation method thereof. Background technique [0002] At present, the existing bactericidal composition for preventing and treating banana scab, for example, Chinese patent CN 104068034 A discloses a "bactericidal pesticide composition", including three active components A, B, and C, and the A group The ratio of parts by weight to the B component is 5-85:5-85:5-10, the A active component is pyraclostrobin, and the B active component B is selected from tebuconazole , diniconazole and bifenconazole, the ratio of tebuconazole, diniconazole and bifentriazole by weight is 10:20:30, and the C component is tricyclazole and triclostrobin, and the tricyclic The ratio of azole and trifloxystrobin by weight is 10:15. Another Chinese patent CN104542659A discloses a "fungicidal compos...

AI Technical Summary

Problems solved by technology

For example, wettable powder is easy to cause product sticking, is not easy to disperse and suspend in water, or clogs the nozzle, and causes precipitation in the sprayer, resulting in uneven spraying

[0006] 3), the problem of compounding, through the toxicity test, heat storage stability test and the determination of the mixed co-toxicity coefficient of several specific proportions disclosed by the above-mentioned several bactericidal compositions, it was found that no obvious synergistic effect could be achieved
