Abstract

The invention relates to a herbicide composition for preventing farmland weeds and application, in particular to a herbicide for preventing weeds in rice fields, which is a ternary herbicide mixture composed of butachlor, penoxsulam and mesotrione as active ingredients, and the weight ratio of butachlor to penoxsulam to mesotrione in the composition is (1-65): (0.1-20): (0.1-30). The herbicide composition is reasonable in component, has a control effect superior to the activity of each component used alone, has a synergistic effect, enlarges a weed control spectrum, improves the pesticide application efficiency, reduces the control cost, slows down the generation of weed resistance, has good safety to crops, and meets the safety requirements of pesticide preparations.

Description

technical field [0001] The present invention relates to a pesticide composition, in particular to a pesticide composition for weeding paddy fields, which is a ternary herbicide mixture composed of butachlor, penoxsulam and mesotrione as active ingredients, It belongs to the field of pesticides. Background technique [0002] With the modernization of agriculture, a series of products such as insecticides, fungicides, and herbicides have been widely used. Among them, herbicides are the most popular pesticide products, and the sales of herbicides have always been at the forefront of pesticides. At present, there are many kinds of herbicides on the market, and at the same time, the application technology is also demanding. If there is a little carelessness in the application, problems such as phytotoxicity and poor weeding effect will occur. Improper selection of herbicides will directly affect the safety or yield of people or grass seedlings. With the development of weeding t...
