Technical Field
The invention belongs to the field of pesticides, and particularly relates to a weeding composition containing triazophos-cotrione and pyridazine compounds and application thereof.
Background
Chemical weeding is the most economic and effective means in preventing and removing weeds in farmlands, but the problems of drug resistance and resistance evolution of weeds and the like are easily caused by using a single variety or a single action mode of chemical herbicide continuously at a high dose for a long time.
The chemical structural formula of the triazophone is shown as 
The HPPD inhibitor herbicide is a newly developed HPPD inhibitor herbicide for post-emergence stem and leaf treatment of the paddy field, has excellent biological activity, and can effectively prevent and kill various malignant weeds in the paddy field.
The chemical structural formula of the pyridate is
Is a selective post-emergence herbicide. After the treatment of the stem and leaf, the stem and leaf are quickly absorbed by the leaf, the Hill reaction of photosynthesis is blocked, the leaf of the weed turns yellow and stops growing, and the weed withers and dies. Is suitable for preventing and killing broad-leaved weeds of cereal crops such as wheat, rice, corn and the like, and particularly has good preventing and killing effect on cleavers, amaranthus retroflexus and certain local weeds.
The structural formula of the compound cyclopyromate (test code number H-965) is shown in the specification
Is a pyridazine herbicide developed by Mitsui chemical Co., Ltd., Japan, and is a photosystem II inhibitor. The creation may be based on the structural derivation of pyridate and pyridaben.
The reasonable compounding or mixing of the herbicide compound has the advantages of expanding the weed spectrum, improving the control effect, delaying the occurrence and development of drug resistance and drug resistance of weeds and the like, and is one of the most effective methods for solving the problems. Therefore, the development of a weeding composition variety which has high safety and wide weed control spectrum, can produce synergistic effect and solve the problem of resistant weeds is urgently needed in production.
