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 fungicides, it was found that no obvious synergistic effect could be achieved

Abstract

The invention discloses a pyraclostrobin and epoxiconazole compound suspending agent and a preparation method thereof and relates to the technical field of control on the leaf spot disease of banana crops and the false smut of rice crops. Every 1 L of the suspending agent is prepared from 80 g of pyraclostrobin, 120 g of epoxiconazole, 3 g of fatty alcohol-polyoxyethylene ether, 5 g of styrylphenol polyoxyethylene ether, 0.5 g of xanthan gum, 0.3 g of sodium benzoate, 0.5 g of a defoaming agent and the balance of deionized water. All raw materials are sucked into a preparation reactor to be mixed, subjected to preliminary grinding by a colloid mill and then subjected to fine grinding by a sand mill, sampling and analysis are performed, and filtration, metering, package and warehousing are performed after qualification. The pyraclostrobin and epoxiconazole compound suspending agent has good effects of controlling the leaf spot disease of the banana crops and the false smut of the rice crops, and obvious synergistic effects of the pyraclostrobin and the epoxiconazole can be realized.

Description

Technical field [0001] The invention relates to the technical field of leaf spot disease of banana crops and rice smut disease of rice crops, in particular to a compound suspension of pyraclostrobin and epoxiconazole and a preparation method thereof. Background technique [0002] At present, the existing fungicides for leaf spot disease and rice smut control, for example, Chinese patent "CN102283227A" discloses a "bactericidal composition containing pyraclostrobin and epoxiconazole", the weight ratio is 50:1~1:60 pyraclostrobin and epoxiconazole are compounded. Another Chinese patent "CN103563942A" discloses a "bactericidal composition containing pyraclostrobin and epoxiconazole and its application", using pyraclostrobin and fluorine in a weight ratio of 1~70:1~50 Cycazole is compounded. [0003] The inventor has verified through long-term experiments that the above-mentioned fungicides mainly have the following defects: [0004] 1). Through experiments on several specific ratios ...
