Abstract

The invention relates to a wettable diniconazole powder and a preparation method thereof, and belongs to the technical field of chemical industry. The wettable diniconazole powder comprises the following components in percent by weight: 12.5% of diniconazole raw pesticide, 4%-10% of an inert filler, 5%-10% of auxiliary agents, and the balance light calcium. The diniconazole raw pesticide, the inert filler and a certain amount of the auxiliary agents are fully mixed in proportion and then crushed to certain powder particle fineness, and full mixing is performed. The medicament prepared by the formulation can effectively resist caking, and the fluffy fluidity of the powder is good. The auxiliary agents are added, the penetration ability and the wetting expansion ability of the medicament areenhanced, the medicament can be quickly absorbed by bacterial cells, the normal development of the bacterial cells is interfered by the conduction of the medicament in the bacterial cells, and thus bacteriostatic and bactericidal effects are achieved. The wettable diniconazole powder prepared by the above formulation and method has low toxicity, environmental protection and high efficiency, and has good economic and ecological benefits.

Description

Technical field [0001] The invention relates to the technical field of pesticides, in particular to a wettable powder of diniconazole and a preparation method thereof. Background technique [0002] Since the reform and opening up, my country’s agricultural science and technology has developed rapidly, and farmers’ demand for pesticides has also increased year by year. However, the increase in agricultural use has also led to outstanding environmental problems. With the increasingly stringent environmental protection requirements, the development of high-efficiency and low-toxicity , Low-residue pesticides are imminent. Diniconazole is a triazole fungicide. It inhibits 14α-demethylation in the biosynthesis of fungal ergosterol, causing ergosterol deficiency, resulting in abnormal fungal cell membranes, and ultimately fungus death, with a long duration of effect. It has excellent protection, treatment, eradication and internal absorption to the top conduction, and has a wide antiba...
