Methoxyfenozide and indoxacarb compound suspending agent and preparation method thereof

Abstract

Relating to the technical field of paddy rice leaf roller control, the invention provides a methoxyfenozide and indoxacarb compound suspending agent and a preparation method thereof. The compound suspending agent is prepared from at least 20 parts of methoxyfenozide, 10 parts of indoxacarb, 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 a defoaming agent, and the balance deionized water. The preparation method consists of: pumping all the raw materials into a preparation kettle, conducting mixing, and performing preliminary grinding by a colloid mill, then carrying out fine grinding by a sand mill, conducting sampling analysis, if the analysis result is qualified, carrying out filtering, metering, packaging and warehousing. The 30% compound suspending agent of methoxyfenozide and indoxacarb mixed in a ratio of 2:1 can play an obvious synergistic role, while other preparations mixed in other ratios cannot reach an obvious synergistic effect.

Description

technical field [0001] The invention relates to the technical field of rice leaf roller control, in particular to a compound suspending agent of methoxyfenozide and indoxacarb and a preparation method thereof. Background technique [0002] At present, the existing insecticidal composition for controlling rice leaf roller, for example, Chinese patent CN103999875 A discloses a "rice leaf roller insecticide and its preparation method", the active component is composed of Suyun Composed of Chrysobacterium, Streptomyces griseus and Kangkuan, the weight ratio of the Streptomyces thuringiensis, Streptomyces grayus and Kangkuan is (1-10):(1-10):(10-1). Another Chinese patent "CN 103918674 A" discloses a "insecticide for the control of rice leaf rollers", the active ingredients are emamectin benzoate and pyriproxyfen, the weight ratio of which is 2:83, and the effective dose of emamectin benzoate Salt and pyriproxyfen with solid or liquid carrier, assistant and other additives.

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
