Abstract
The invention relates to a herbicide composition containing cyhalofop-butyl and amides. The herbicide composition is mainly characterized by comprising the following materials in percentage by weight: 1 to 40 percent of cyhalofop-butyl serving as an active ingredient A, 5 to 50 percent of active ingredient B, auxiliary agents and other excipients, wherein the active ingredient B is selected from alachlor, acetochlor, butachlor, mefenacet, metolachlor and propisochlor; and the herbicide composition is prepared into wettable powder, suspension, water emulsion or microemulsion. The herbicide composition is used for preventing and controlling annual gramineous weeds in paddy fields.
Description
Technical field
The invention belongs to technical field of pesticide, be specifically related to a kind of contain the effective constituents A cyhalofop-butyl with the Herbicidal combinations of amide-type, be used to prevent and treat paddy field grassy weed, broad leaved weed and sedge weed.
Background technology
The direction of pesticide developing was to embody efficient, low toxicity, low-residual and pollution-free in recent years.Be embodied in pursuit " three height ", promptly (1) is safe, and this not only requires toxicity low, and is residual low, and nuisanceless; (2) biologically active height; (3) selectivity height.Therefore continue to improve the performance of present Pesticidal products, reach efficient, low toxicity, free of contamination requirement.So, select the agricultural chemicals of composite mixture just to become current first-selection and a kind of valid approach, be that the agricultural chemicals of performance complement obtains best synergistic effect by the proportioning of adjusting different agricultural chemicals.
Cyhalofop-butyl (cyhalofop-butyl), molecular formula: C

2Molecular weight: 283.8, chemical name: 2-chloro-N-(2-ethyl-6-methylbenzene)-N-[(1-methylethoxy) methyl], by the chloro-acetyl amine weed killer herbicide of Hungary nitrogenize joint-stock company exploitation.Propisochlor mainly passes through the synthetic growth that suppresses cell of impede protein matter.Medicament absorbs by plant plumule, enters the synthetic of the interior Profilin enzyme of plant corpus, and bud and root elevator are lived growth, and adventive root can't form.Be used to prevent and treat annual gramineous weed and part broad leaved weed.
The chemical composition of each weed killer herbicide, structure and physicochemical property all are distinguishing.Therefore, they kill careless ability and scope is also different.It is narrower that some weed killer herbicide kills the grass spectrum, but have one's own knack, and can eradicate the weeds that are difficult to eliminate with other weed killer herbicide.
Nineteen fifty-five has the people to report that Amrol can increase the prevent and kill off effect beginning of dalapon to the stone thatch, after, along with further developing of weed killer herbicide production and application, using with gradually between the weed killer herbicide grows up.China also comparatively payes attention to using with aspect the research of weed killer herbicide, is recognized extensively that to do be one of important measures of rationally using of weed killer herbicide, has worked out a series of Herbicidal compositions, has obtained bigger progress.
My company also is devoted to the research and development of Herbicidal compositions.At present, do not appear in the newspapers about the relevant composite product of cyhalofop-butyl with alachlor, Acetochlor, butachlor, mefenacet, isopropyl methoxalamine, propisochlor.
