Technical Field
The invention belongs to the field of herbicides, and particularly relates to a weeding composition containing rimsulfuron, halosulfuron-methyl and flufenacet and application thereof.
Background
The rimsulfuron is a sulfonylurea herbicide, has the advantages of high selectivity, high efficiency, low toxicity and the like, is absorbed by root leaves and quickly conducted to meristematic tissue, and can prevent and kill annual gramineous weeds, nutgrass flatsedge and broadleaf weeds in corn fields, such as: autogenous wheat seedlings, crabgrass, barnyard grass, green bristlegrass herb, wild oat, wild sorghum, polygonum, dayflower, shepherd's purse, purslane, redroot amaranth, wild corn, cyperus rotundus and the like. The halosulfuron-methyl is a sulfonylurea selective systemic conduction type herbicide, and the herbicide is absorbed by the leaves and roots of weeds and conducted to each part to hinder the biosynthesis of amino acid in the weeds, prevent the division of weed cells and the growth of plants, and gradually die after withering, so that the herbicide can effectively prevent and kill various annual broadleaf weeds and sedge weeds in corn fields and sugarcane. Flufenacet belongs to the class of aryloxyacetamides, inhibitors of cell division and growth, selective herbicides. Can effectively prevent and kill off annual weeds in corn fields such as green bristlegrass, barnyard grass, crab grass and the like, and annual weeds in winter wheat fields such as beckmannia syzigachne, alopecurus davidii, alopecurus japonicus, hardwood and the like, and also has a certain inhibiting effect on broad-leaved weeds
The single use of the herbicide for a long time easily causes the serious drug resistance of the weeds, thereby increasing the application dosage of the herbicide, causing pollution to the environment, and finding the synergistic composition which can improve the weeding effect and reduce the application dosage of the active ingredients is a research and development hotspot. In the prior art, the complex use of rimsulfuron, halosulfuron-methyl and flufenacet is not reported.
