Problems solved by technology
Cotton is a dicotyledonous crop, which is sensitive to various herbicides. The choice of herbicide species is limited, the technical requirements for use are relatively strict, the herbicidal spectrum is narrow, and the safety is low. Weeds, therefore, there is an urgent need to develop herbicides that can effectively control weeds in cotton fields

Abstract
The invention provides a herbicide composition for a cotton field, a preparation thereof, and application and an application method of of the composition and the preparation, and relates to the technical field of herbicides. The herbicide composition for the cotton field comprises a herbicide A and a herbicide B. The herbicide A is fluridone, and the herbicide B is selected from at least one of a long-chain fatty acid synthesis inhibitor, a microtubule assembly inhibitor, a mitotic inhibitor, a lipid synthesis inhibitor, a photosynthetic system IIA site inhibitor and a fatty acid thioesterase inhibitor. Through mutual synergistic interaction of the herbicide A and the herbicide B, after the herbicide composition preparation is applied to the cotton field, the weed control effect is high, the herbicide controlling spectrum is wide, the safety is good, the selectivity coefficient between cotton and weeds is obviously higher than that of a single herbicide, the yield increasing effect is obvious, meanwhile, the generation of resistance of the single herbicide is delayed, the cost is low, and the herbicide composition preparation is easy to popularize.
Description
technical field [0001] The invention relates to the technical field of herbicides, in particular to a herbicide composition for cotton fields and its preparation, application and application method. Background technique [0002] Cotton belongs to the Malvaceae family and is an important economic crop and source of textile fiber raw materials in the world. There are many factors affecting the yield and quality of cotton, and weeds are one of the factors restricting the sustainable development of cotton. The proportion of weed damage in cotton fields is as high as 56%, causing 14-16% cotton yield loss every year. Weed hazards include: competing with cotton for glory, water and fertilizer, and space; transferring hosts and spreading pests and diseases; greatly increasing the physical and chemical costs of cotton planting (fertilizers, artificial inputs); increasing irrigation costs; reducing cotton production and cotton fiber quality. Therefore, weeding in cotton fields is an...
