The compound suspension concentrate disclosed by the invention has strong affinity with the soil, the pesticide effect is increased, and the field application amount is reduced, and thus the production cost and the application cost are lowered, and the pesticide residues and environmental pollution are reduced.
Description
Technical field
The present invention relates to a kind of farm weeding preparation, in particular a kind of composite aqueous suspension agent containing oxadiargyl and Oxyfluorfen, preparation method and application thereof.
Background technology
Oxadiargyl system proporphyrinogen oxidase inhibitor is before a kind of diazolones seedling and early stage herbicide after seedling.Young shoot before and after mainly being emerged by some susceptible weeds is contacted with seedling and absorbs and work, and is a kind of contact killing type weed killer herbicide, mainly absorbs in the contact of weeds germination and emergence and works.Be mainly used in paddy field weed-killer, also effective to the peanut, cotton, sugarcane etc. of dry land; Barnyard grass, moleplant seed, ditch millet, difformed galingale herb, Monochoria vaginalis, mexicana, globe daisy alkali grass, Sagittaria pygmaea etc. are prevented and kill off for rice field.Also can be used for preventing and kill off crop annual gramineous weed and the broad leaved weeds such as cotton, soybean, sunflower, peanut, potato, sugarcane, celery, fruit tree.To looking for section, Li Ke, Euphorbiaceae, Zui Jiangcao section, optically-active section weeds have good preventive effect.
Oxyfluorfen is before contact killing type selectivity bud or post-emergence herbicide, playing its activity of weeding, entering in plant corpus mainly through coleoptile, mesocotyl when there being light, less through root absorption, and has denier upwards to be transported by root to enter leaf portion.The scope of application is wide, herbicide pedigree is wide, lasting period is long, mu consumption is few, active high, can use with mixture of herbicides, expand herbicide spectrum, improve drug effect, for before cotton, round onions, peanut, soybean, beet, fruit tree and vegetable fields bud, use after bud prevent and kill off barnyard grass, sesbania, downy brome, green foxtail, datura, quackgrass, artemisiifolia, thorn chrysanthemum are twisted with the fingers, Tong fiber crops, charlock unifacial leaf and broad leaved weed.Transplanting rice, soybean, corn, cotton, peanut, sugarcane, vineyard, orchard, the unifacial leaf of vegetable fields and forest nursery and broad leaved weed can be prevented and kill off.Dryland rice dispenser can be mixed with butachlor; In dispensers such as soybean, peanut, Cotton Fields, can be mixed with alachlor, trefanocide etc.; In place's dispensers such as orchards, can be mixed with paraquat, glyphosate.
On Agriculture Field control of weeds, often there is defect in various degree in the weed killer herbicide kind containing single-activity component, as weeds after continuous administration easily develop immunity to drugs, herbicide spectrum is narrow, using repeatedly can weighting ring environment pollution, and residue of pesticide extend.Different cultivars composition carries out composite, is the modal method of control Herbicide-resistant weeds.
Current paddy field major herbicides is second benzyl, fourth benzyl and benzyl dichloride, get more and more owing to using resistant weed for a long time, cause a large amount of underproduction of crop, for current severe situation, in production, urgent need finds rice safety, to the efficient combinations of herbicides of weeds, in order to replace conventional weed killer herbicide.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of composite aqueous suspension agent containing oxadiargyl and Oxyfluorfen, preparation method and application thereof, open up the novel form of herbicide for paddy field application.
