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 effective constituents A cyhalofop-butyl and Herbicidal combinations with amide-type of containing, for preventing and treating 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 ", (1) is safe, and this not only requires toxicity low, residual low, and nuisanceless; (2) biologically active is high; (3) selectivity is high.Therefore continue to improve the performance of current 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 effectively approach, be that the agricultural chemicals of performance complement obtains best synergistic effect by adjusting the proportioning of different agricultural chemicals.
Cyhalofop-butyl (cyhalofop-butyl), molecular formula: C

20fNO
4, relative molecular mass 357.4.It is the aryloxy carboxylic acid weed killer herbicide of LG-DOW agricultural science company exploitation.Seem unique kind paddy rice to tight security in fragrant phenoxy phenoxy propionic acid weed killer herbicide, there is interior suction conductivity, blade and the leaf sheath carried by plant absorb, phloem conduction, accumulates the meristem zone in plant corpus, always acetyl-CoA carboxylase, fatty acid is synthesized to be stopped, the division of cell can not normally be carried out, and film system etc. are destroyed containing ester structure, finally cause plant death.In paddy rice body, cyhalofop-butyl can be degraded to rapidly the diacid state to acetyl-CoA carboxylase non-activity, paddy rice is had to the safety of height, and in soil and in typical paddy field water either, degraded rapidly.Be mainly used in preventing and treating grassy weed, not only efficient to barnyard grass, also can prevent and treat the weeds such as moleplant seed, lady's-grass.
Alachlor (alachlor), molecular formula: C
14h
20clNO
2chemical name: alpha-chloro-2 ', 6 '-diethyl-N-methoxy acetanil, relative molecular mass 269.8, is the chloro-acetyl amine weed killer herbicide of being developed by Monsanto Company, is mainly that it enters Profilin enzymic activity in plant corpus by the synthetic growth that suppresses cell of impede protein matter, protein cannot be synthesized, cause bud and root to stop growing, adventive root cannot be formed, make weeds cause death.
Acetochlor (acetochlor), molecular formula: C

20clNO
2chemical name: 2 '-ethyl-6 '-methyl-N-(ethoxymethyl)-2-chloro acetanilide, relative molecular mass 269.8, Acetochlor is the synthetic growth that suppresses cell by impede protein matter, be that Acetochlor enters the synthetic of the interior protease inhibition of plant corpus, young shoot, young root are stopped growing.The curling atrophy of grassy weed performance young leaves, other are shrinkage also, and whole strain is withered.Broad leaved weed leaf shrinkage flavescence, whole strain is withered.
Butachlor (butachlor), is also Machete, weed eradication spy, molecular formula: C
17h
26clNO
2, chemical name: N-(fourth oxygen methyl)-α-chloro-α ', 6 '-diethyl acetanil, relative molecular mass 311.9.Be the chloro-acetyl amine weed killer herbicide of being developed by Monsanto Company, mainly by the synthetic growth that suppresses cell of impede protein matter, absorb by weeds young shoot and immature secondary root, suppress the synthetic of body internal protein, make the enlargement of weeds shoot, deformity, color depth is green, finally causes death.
Mefenacet (mefenacet), is also mefenacet, molecular formula: C

2, molecular weight: 283.8, chemical name: 2-ethyl-6-methyl-N-(1 '-methyl-2 '-methoxyethyl) chloro acetanilide, the chloroamides class weed killer herbicide of being developed by Novartis Co.,Ltd.Isopropyl methoxalamine is mainly by the synthetic growth that suppresses cell of impede protein matter.The hypocotyl that is monocotyledonous coleoptile, dicotyledon by the young shoot of plant absorbs upwards conduction, also Assimilation and conductivity of seed and root.Susceptible weeds is before germination is unearthed afterwards or be just unearthedly poisoned to death immediately.
Propisochlor (propisochlor), has another name called propachlor, molecular formula: C
15h
22clNO
2molecular weight: 283.8, the chloro-N-of chemical name: 2-(2-ethyl-6-methylbenzene)-N-[(1-methylethoxy) methyl], by the chloro-acetyl amine weed killer herbicide of nitrogenize joint-stock company of Hungary exploitation.Propisochlor is mainly by the synthetic growth that suppresses cell of impede protein matter.Medicament absorbs by plant plumule, enters the synthetic of the interior protease inhibition of plant corpus, and bud and root elevator are lived growth, and adventive root cannot form.Be used for preventing and treating annual gramineous weed and part broad leaved weed.
The chemical composition of each weed killer herbicide, formation and physic-chemical property are all distinguishing.Therefore, their herbicide ability and scope are also different.Some weed killer herbicide herbicide spectrum is narrower, but has one's own knack, and can eradicate the weeds that are difficult to elimination with other weed killer herbicide.
Nineteen fifty-five has people to report that Amrol can increase dalapon the effect of preventing and kill off of stone thatch is started, after, along with further developing that weed killer herbicide is produced and applied, using with between weed killer herbicide grows up gradually.China also comparatively payes attention to aspect the mixed research of weed killer herbicide, is extensively recognized as one of important measures of rationally use of weed killer herbicide, has worked out a series of Herbicidal compositions, has obtained greater advance.
My company is also devoted to the research and development of Herbicidal compositions.At present, have no report about cyhalofop-butyl to the relevant composite product of alachlor, Acetochlor, butachlor, mefenacet, isopropyl methoxalamine, propisochlor.
