Description
Technical Field
The invention relates to a weeding composition, in particular to a weeding composition containing triazophos-cotrione and monosulfuron ester, and belongs to the technical field of pesticide compounding.
Background
The triazophone is a compound of an HPPD enzyme inhibitor, has a systemic conduction effect, can be absorbed by various ways such as leaves, roots and stems of weeds, and is not easy to turn green and relapse; the action mechanism of the compound is that the activity of key chromoenzyme for photosynthesis is controlled by inhibiting a plant body, so that the process of converting a substrate into the homogentisic acid is hindered, the normal synthesis of tocopherol and plastoquinone cannot be realized, the synthesis of carotenoid in a target body is influenced, the yellow and white leaves are caused, the normal operation of the photosynthesis in the plant body is influenced, and finally the plant body is completely dead.
The monosulfuron ester is an acetolactate synthase inhibitor, and is a sulfonylurea herbicide with systemic property and conductivity; so that the plant stops growing due to the obstruction of protein synthesis.
The herbicide variety containing a single active component has defects of different degrees in weed control, and after continuous use, weeds are easy to generate drug resistance, so that the problems of narrow weed control spectrum, environmental pollution and the like occur. The reasonable compounding of the herbicide is an effective method for improving the preventing and killing effect, expanding the weed control spectrum, delaying the drug resistance of weeds, reducing the environmental pollution, reducing the use cost and reducing the herbicide residue. The applicant unexpectedly finds that the mixture of the triazophone and the monosulfuron ester with different action mechanisms has obvious synergistic control effect on various broad-leaved weeds such as the carignane, the black nightshade herb, the monochoria vaginalis, the redroot amaranth, the dwarf sagittaria and the like and gramineous weeds such as the moleplant seed, the barnyard grass and the like, obviously improves the control effect on the broad-leaved weeds and the gramineous weeds in the wheat field, enlarges the weed control spectrum, has the advantages of reducing the dosage and the control cost, and simultaneously improves the safety on crops. And the blending of the triazophone and the monosulfuron ester is not reported after retrieval.
