Problems solved by technology

Traditional pesticides are single-dose, single-dose effect is single, and long-term use leads to continuous improvement of crop resistance, which has a serious impact on the effect of pesticides. Farmers often use increased dosage to maintain the effect, which increases the cost of use and causes damage to the environment.

Abstract

The invention discloses a pyrazosulfuron-ethyl.butachlor wettable powder and its preparation method. The pyrazosulfuron-ethyl.butachlor wettable powder comprises (by wt%) pyrazosulfuron-ethyl 1.4, butachlor 26.6, sodium lignosulfonates 10, white carbon black 20, and light calcium carbonate 42. The preparation method includes mixing pyrazosulfuron-ethyl, butachlor and other fillers according to certain proportions into pyrazosulfuron-ethyl.butachlor pesticide compound which is a transplanting field herbicide for paddy field and to control partial perennial weeds and annual weeds, and has the characteristics of safety to rice, broad weed killing spectrum, long effective duration, and convenient use.

Description

technical field [0001] The invention relates to a compound pesticide, in particular to a pyrazole-butachlor wettable powder and a preparation method thereof. Background technique [0002] According to the principle of one drug with multiple treatments, the pesticides formulated by the compound preparation method according to a certain mixing ratio are called compound pesticides. Traditional pesticides are single-dose, single-dose effect is single, and long-term use leads to continuous improvement of crop resistance, which has a serious impact on the effect of pesticides. Farmers often use increased dosage to maintain the effect, which increases the cost of use and causes damage to the environment. . Contents of the invention [0003] Purpose of the invention: the purpose of the present invention is to provide a kind of wettable powder of pyrazole butachlor in order to solve the deficiencies in the prior art. [0004] Another object of the present invention is to provide ...
