Abstract

The invention relates to a method for producing wettable powder through the compound of validamycin A and propiconazole. The method comprises following steps of (1) adding 2-5 times volume of absolute ethyl alcohol or acetone into original propiconazole based on the volume of the original propiconazole, and dissolving; (2) adding white carbon black into the propiconazole ethyl alcohol solution or propiconazole acetone solution, fully mixing so as to form pulp; (3) vacuum drying, and smashing so as to obtain propiconazole mother powder; (4) fully mixing with wetting dispersant and kaolin; (5) smashing through airflow; (6) adding original medicine powder containing 60%-70% of validamycin A, and mixing to obtain a mixture; (7) performing multipoint sampling and detecting on the mixture, packaging and putting in storage after all indexes are qualified through detection. The method is reasonable and is convenient to operate, the homogeneity of medicines of the prepared wettable powder product is good, the suspensibility of the wettable powder is high and is greater than or equal to 85%.

Description

Technical field [0001] The invention relates to the field of pesticides, in particular to a production method for preparing a wettable powder with Jinggangmycin A and propiconazole. Background technique [0002] Validamycin, also known as Validamycin, English name: Validamycin, a low-toxicity bactericide, is an antibiotic produced by actinomycetes. It has strong systemic properties and is easily absorbed by bacterial cells and quickly within it. Conduct, interfere with and inhibit the growth and development of bacterial cells. It is mainly used for rice sheath blight, but also for the prevention and control of rice smut, corn spot and vegetable, cotton, beans and other crop diseases. [0003] Propiconazole, the English common name: propiconazole, is a systemic triazole fungicide with protective and therapeutic effects. It can be absorbed by roots, stems, and leaves, and can be quickly transmitted upwards in the plant body. Prevent and control diseases caused by ascomycetes, basid...
