Abstract

The invention relates to the field of pesticide preparations, and discloses a weeding composition and a preparation thereof. The weeding composition comprises flupoxam and clethodim. According to the weeding composition and the preparation thereof, the flupoxam and the clethodim are compounded to be taken as effective components, and have complementary advantages and a synergistic effect so as to delay the generation of pesticide resistance of weeds; and meanwhile, the weeding composition has a synergistic effect to weeds in a soybean field, so that the pesticide consumption and the pesticide applying frequency are greatly reduced, has the advantages of safety, high efficiency, environmental friendliness and the like, and can be widely applied to the control on the weeds in the soybean field.

Description

technical field [0001] The invention relates to the field of pesticide preparations, in particular to a herbicidal composition and its preparation. Background technique [0002] Soybeans, also known as soybeans, green beans, and black beans, are the main oil crops in my country and an important non-staple food raw material. They have been planted in my country for 5,000 years. Soybean is the most nutritious and easily digestible food in the legume family. It is rich in protein and is an important source of food and feed. [0003] my country's soybean planting area is about 6.7 million hectares, and weeds are common and various in variety. These weeds seriously affect the yield and quality of soybean. The main weed damage areas include Northeast China, Huanghuaihai Region, Yangtze River Basin and South China. Due to differences in geographic location, climate, soil and farming systems, the types, distribution, dominant and subdominant species of weeds in soybean fields are ...
