Description

Herbicidal active ingredient composition and herbicide composition Technical Field The invention relates to the field of agriculture, in particular to a weeding composition containing cyclohexenone herbicide, flurbiproflumilast and metamifop, and application and a method for preventing and controlling agricultural weeds. Background Cyclohexenone herbicides are an important class of herbicides with unique mechanism of action and broad range of application, which block protein synthesis by inhibiting acetyl-coa carboxylase, thereby achieving herbicidal objectives. The cyclohexenone herbicide has high selectivity, can effectively prevent and remove various grassy weeds, including annual and perennial weeds, has good systemic property, can be quickly absorbed by weed stems and leaves after the herbicide is applied, and is transmitted to root systems and growing points. Important varieties of cyclohexenone herbicides include graminezil, sethoxydim, clethodim, fenpropion, and the like. The cycloxaprid pure product is white or off-white powder, is developed by Basoff company, is insoluble in water, and can be dissolved in organic solvents such as ethanol, acetone and the like. The herbicide is absorbed and transferred by plants after foliar application, is used for preventing and killing grassy weeds such as barnyard grass, crab grass, euphorbia lathyris, green bristlegrass and the like in crop fields such as rice and the like, and is safe for direct seeding rice and transplanted rice. The benpropenone is a herbicide variety created by Shandong Miaodan chemical Co., ltd, is mainly used for crop fields such as rice, and has good control effect on barnyard grass, moleplant seed, paspalum distichum and the like. The chlorofluoropyridine ester is aryl pyridine formate compound developed by the Dow company, belongs to auxin herbicide, is a white crystalline solid, and has the action mechanism of causing the excessive stimulation of specific auxin regulating genes and interfering the growth process of plants. The chlorofluoropyridine ester can be absorbed by leaves and roots of weeds and is transmitted to other places from xylem and phloem, so that the weeding activity is exerted. After the two leaves of the rice are applied at one heart, grass weeds such as barnyard grass, moleplant seed and the like, broadleaf weeds such as amaranth, arrowhead and the like, and sedge weeds such as cyperus esculentus, cyperus rotundus and the like are prevented and treated. The oxazoxamide is an aryloxy phenoxy propionate herbicide developed by Korean institute of chemical technology, and the pure product is light brown powder, and has the action mechanism of inhibiting acetyl coenzyme A carboxylase, is mainly used for preventing and killing most annual grassy weeds in transplanting and direct seeding fields, and has low toxicity and environmental safety. It is suitable for transplanting and direct seeding Tian Shemian spraying, and mainly absorbed by plant stem and leaf, and the effective components enter plant body to play a role. The weeding composition has high safety to rice, and can effectively prevent and remove annual gramineous weeds such as barnyard grass, semen Euphorbiae, crabgrass, goosegrass and the like in the rice field. CN106719675A discloses a herbicidal composition for paddy fields, wherein the first active ingredient is flurbiproflumilast and the second active ingredient is any one of cyhalofop-butyl and oxazoxamide, and the herbicidal composition can remarkably expand the herbicidal spectrum and improve the overall preventing and killing effect on weeds in paddy fields. CN107027770a discloses a weeding composition with synergistic effect, the effective components of the weeding composition are metamifop, fluroxypyr and fluroxypyr, the weeding composition is mainly applied to preventing and killing weeds in paddy fields, and compared with single-dose single use or mutual binary compound use, the weeding composition has the advantages of obviously improved weeding effect, enlarged weeding spectrum and long lasting period, and is safe to rice. CN113575593a discloses a complex formulation comprising flurbiproflumilast and oxazamate, which can be formulated into various dosage forms for controlling grassy and broadleaf weeds in paddy fields. CN107751212a discloses a ternary paddy field weeding composition containing A, B, C three active ingredients, wherein the active ingredient a is metamifop, B is one of cyhalofop-butyl or clomazone, and C is fluroxypyr. The weeding composition can effectively enlarge the weeding spectrum, and has obvious synergism on the resistant barnyard grass which is difficult to control by the pesticide effect in the current paddy field. CN117770264a discloses a herbicidal composition containing propanil, oxazachlor and flurbiproflumilast, which is used for stem and leaf spray control of annual weeds in paddy fields, and is particularly excellent for cyhalofop-butyl resistant biological horses T
