Abstract

The invention discloses a prochloraz and isoprothiolane compound missible oil and a preparation method thereof, relating to the technical field of control of pyricularia oryza. The missible oil is prepared from the following components in parts by weight: 12 parts of prochloraz, 36 parts of isoprothiolane, 3.75 parts of tristyrylphenol polyoxyethylene ether, 3.75 parts of distyrylbenzene phenol-formaldehyde condensate polyoxyethylene ether, 7.5 parts of calcium dodecyl benzene sulfonate and 37 parts of xylene. The preparation method comprises the following steps: adding the prochloraz and isoprothiolane into xylene, and stirring until the materials are totally dissolved; adding the tristyrylphenol polyoxyethylene ether, the distyrylbenzene phenol-formaldehyde condensate polyoxyethylene ether and the calcium dodecyl benzene sulfonate, uniformly stirring and mixing by virtue of a reaction kettle, sampling and analyzing the content, standing, filtering and packaging after the product is qualified, sampling and analyzing the content again, and warehousing after qualification. The 48 percent of prochloraz and isoprothiolane compound missible oil is compounded by mixing the prochloraz and isoprothiolane according to a ratio of 1:3, an obvious synergistic effect can be achieved, and the other preparations mixed according to the ratio cannot achieve the obvious synergistic effect.

Description

technical field [0001] The invention relates to the technical field of rice blast fungus prevention and control, in particular to a prochloraz and rice blastling compound cream and a preparation method thereof. Background technique [0002] At present, the existing pesticides for rice blast fungus, for example, Chinese patent "CN 101617687 A" discloses a "bactericidal compound", wherein prochloraz and rice blastil are used as active ingredients, wherein prochloraz The weight ratio of rice blast spirit is 5-25:20-40. [0003] The inventor has verified through long-term tests that the bactericidal compound mainly has the following defects: [0004] 1), by testing several specific proportions disclosed by the above-mentioned bactericidal compound, it is found that the control of rice blast fungus cannot have a good control effect. [0005] 2), for the several dosage forms disclosed by the above-mentioned bactericidal compound, it is found that there are defects of different p...
