Description
Technical Field
The invention belongs to the field of pesticides, and particularly relates to a mixed herbicide containing halauxifen-methyl and quinclorac and application thereof.
Background
The fluroxypyridine ester is a novel aryl picolinic acid herbicide, is a second novel compound in the herbicides following the fluroxypyridine ester, and can effectively prevent and kill gramineous weeds such as barnyard grass, paspalum, cockspur grass, moleplant seed and the like in a paddy field, cyperaceae weeds such as cyperus rotundus, cyperus esculentus, cyperus rotundus and day-light fimbristylis, broad-leaved weeds such as piemarker, rhizoma alismatis, amaranth, ragweed, chenopodium album, horseweed herb, mother grass, ludwigia octovalvis, monochoria indica, xanthium sibiricum and the like. After the herbicide is applied, the herbicide is absorbed by the leaves and root systems of the weeds, has systemic property, can be conducted through xylem and phloem, and is accumulated in meristems of the weeds, so that the herbicidal activity is exerted. Due to the novel action mechanism, the weed herbicide can solve the known weed resistance problem, is environment-friendly and is safe to other organisms.
The quinclorac is a novel herbicide independently developed in China, is an HPPD inhibitor, and has the action characteristics that roots and leaves of weeds are absorbed and conducted to play a role, and sensitive weeds can absorb the herbicide to inhibit the synthesis of p-hydroxyphenylpyruvate dioxygenase to cause the accumulation of tyrosine, so that the synthesis of plastoquinone and tocopherol is hindered, the biosynthesis of carotenoid is further influenced, and the weeds die after albinism. The herbicide is used for preventing and killing gramineous crops, particularly monochoria vaginalis, green bristlegrass, large crabgrass and various broad-leaved weeds which are difficult to prevent and kill at present, is absorbed by leaves or roots after being applied to the weeds, moves up and down in plants and is quickly transmitted to the whole plants.
The compounding of the herbicides can solve the problems of high toxicity and poor effect of a single pesticide, the investment is low, the research and development period is short, the generation of drug resistance of an agent can be delayed by the interactive use of different pesticides, and the herbicide has an ideal use effect, so that the compounding of the pesticides with different action mechanisms is a research hotspot in the field of pesticides at present. In the prior art, no herbicidal composition compounded by the fluroxypyr-meptyl and the quinclorac-mefone is available.
