Weeding composition and application thereof

Abstract

The invention relates to a weeding composition. The active components of the weeding composition include a compound (A) and a compound (B), wherein the compound (A) is metazosulfuron or salt of metazosulfuron; the compound (B) is pyribenzoxim; and the weight ratio of the compound (A) to the compound (B) is (6 to 1)-(50 to 1). The invention further relates to use of the weeding composition in the prevention and control of the germination and growth of undesired plants such as broadleaf weeds, cyperaceae weeds and grassy weeds in paddy, wheat, barley, rye, oilseed rape, low-erucic acid oilseed rape, beet, corns, turf, cotton, vegetables, sugarcane and soybeans.

Description

Technical field [0001] The present invention relates to the field of agriculture, specifically to a herbicidal composition; and to the use of the herbicidal composition to prevent and control unwanted plant germination or growth. Background technique [0002] The world's food production suffers huge losses every year due to diseases, insect pests, and weeds. Crops are attacked by various weeds almost throughout the entire growing season. Weed damage is also a key factor restricting crop yields. Therefore, the prevention and control of agricultural weeds has always been the most concerned and important issue in agricultural production. [0003] The use of chemical herbicides is one of the important symbols of modern agriculture. In recent years, the sales of herbicides have increased year by year, and the application area has also expanded year by year. However, with the continuous use of many herbicide varieties in large areas, many problems have arisen. For example, the pr...
