Ethofenprox and methoxyfenozide compound suspending agent and preparation method thereof

Abstract

The invention provides an ethofenprox and methoxyfenozide compound suspending agent and a preparation method thereof, and relates to the technical field of rice planthopper prevention and control. According to the present invention, 100 parts of the ethofenprox and methoxyfenozide compound suspending agent is prepared at least from 10 parts of ethofenprox, 10 parts of methoxyfenozide, 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, 0.3 part of an anti-foaming agent, and the balance of deionized water; the preparation method comprises: sucking all raw materials into a preparation kettle, carrying out mixing stirring, carrying out primary grinding with a colloid mill, carrying out fine grinding with a sand mill, sampling and analyzing, filtering after achieving the qualified standard, metering, packaging, and warehousing; and the obvious synergistic effect can be provided when the 20% ethofenprox and methoxyfenozide compound suspending agent is subjected to mixing use according to the ratio of 1:1 while the obvious synergistic effect cannot be achieved with the other preparations being subjected to the mixing use according to a certain ratio.

Description

technical field [0001] The invention relates to the technical field of rice planthopper control, in particular to a compound suspending agent of etofenprox and methoxyfenozide and a preparation method thereof. Background technique [0002] At present, the existing insecticidal composition for controlling rice planthoppers, for example, Chinese patent "CN 105052984A" discloses a "rice insecticidal composition", which consists of active ingredients A, B, C and commonly used auxiliary ingredients Composition, active ingredient A is selected from chlorantraniliprole, active ingredient B is selected from ethyl spinosad, active ingredient C is selected from clothianidin, thiamethoxam, dinotefuran; active ingredient A, The weight ratio of B and C is 1-20:1-20:1-20. Another Chinese patent "CN101584342A" discloses a "combination of insecticides with synergistic effects on rice planthoppers and borers". The active ingredient ratio of nitenpyram is 10:1-50:1. [0003] The inventor h...

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, by carrying out toxicity test, heat storage stability test and mixing co-toxicity coefficient measurement on several specific proportions disclosed by the above-mentioned several insecticidal compositions, it is found that no obvious synergistic effect can be achieved
