Description
Technical Field
The invention belongs to the field of herbicides, and particularly relates to a weeding composition containing oxadiargyl, anilofos and oxyfluorfen and application thereof.
Background
The oxadiargyl is a selective pre-emergence soil treatment herbicide which mainly inhibits protoporphyrinogen IX oxidase, and after application, the active ingredients of the oxadiargyl can form a drug film on the surface layer of soil, so that target weeds are eliminated in a germination state, and the oxadiargyl is a high-efficiency broad-spectrum rice field selective herbicide. Has obvious effect on annual grassy indigenous weeds, cyperaceae weeds, broad-leaved weeds and certain perennial weeds, and has better control effect on malignant weeds, namely the spirodela polyrhiza. Anilofos is a systemic organophosphorus herbicide. Absorbed by root system and transmitted to bud or leaf to kill weed. Is used for preventing and killing sedge and barnyard grass transplanted in paddy fields. Has strong systemic property and better effect of killing barnyard grass. The oxyfluorfen is a herbicide for rice transplanting fields, after application, the active ingredients of the oxyfluorfen are quickly diffused on the water surface and then sink into the surface layer of soil to form a closed pesticide film, so that target weeds are eliminated in a sprouting state, and meanwhile, the oxyfluorfen has a good contact killing effect on the emerged weeds. Can be used for preventing and treating various annual gramineous and broadleaf weeds in rice fields such as rice barnyard grass, moleplant seed, monochoria vaginalis, herba Equiseti Arvinsis, short arrowhead, felt cow, and shaped Cyperus rotundus.
Patent application CN201210479445 discloses a composition for preventing and removing weeds in paddy fields, wherein the content of anilofos is 1% -30%, the content of oxadiazon is 1% -20%, and the content of oxyfluorfen is 1% -20%. Patent application CN201410692403 discloses a compound suspension concentrate containing oxadiargyl and oxyfluorfen: 5-30% of oxadiargyl, 5-30% of oxyfluorfen, 2-20% of surfactant, 0-6% of suspending aid, 0-1% of thickening agent, 0-1% of defoaming agent, 0-1% of preservative, 0.5-5% of antifreezing agent and water which are complemented to 100%. Patent application CN201610795595 discloses a dispersible oil suspension containing oxadiargyl and oxyfluorfen: 1-10% of oxadiargyl, 5-15% of oxyfluorfen, 10-20% of emulsifying agent, 1-3% of dispersing agent, 1-3% of thickening agent, 1-3% of white carbon black, 3-10% of stabilizing agent and the balance of oil solvent. Pesticide registry PD20181084 discloses a 22% oxa-ethoxy-fluorine suspension; wherein the clofenpyr-methyl is 12 percent, and the oxadiargyl is 10 percent. Pesticide registry PD20172028 discloses a 41% cypermethrin microemulsion; wherein the content of oxyfluorfen is 9 percent, the content of oxadiazon is 12 percent and the content of anilofos is 20 percent. In the prior art, no report is provided about the compound use of oxadiargyl, anilofos and oxyfluorfen.
The long-term single use of the synergistic composition easily causes the drug resistance of weeds, pollutes the environment, and finds the synergistic composition which can improve the weeding effect and reduce the application dosage of active ingredients, thereby being the research and development key point of a plurality of pesticide companies in China.
