Description
Technical field
The present invention relates to a kind of herbicide composition for paddy fields, be specifically related to a kind of for control rice field grassy weed, broad leaved weed and sedge weed weed killer herbicide, it is to be the binary herbicidal composition of Active components by penoxsuam, bensulfuron-methyl.
Background technology
Large-area applications 2 from about the nineteen fifty, 4-drips, since 2 first 4 chlorine are prevented and kill off the paddy field broad leaved weed, paddy field develops rapidly with the weed killer herbicide kind, kind updates, perfect, successively emerge in large numbers the weed killer herbicides such as diphenyl ether, thiocarbamates, amide-type, quinoline carboxylic acid, sulfonylurea, formed the comparatively perfect Chemical Weeding System that is adapted to the paddy rice different planting, become well stimulation indispensable, very important in world's Rice Production.
But, along with numerous weed killer herbicide kinds continue to use in the paddy field large tracts of land, also produce many problems: 1. Weed Resistance is outstanding, wherein comparatively outstanding to the resistance of Stam F-34, dichloro quinolinic acid, butachlor, benthiocarb with barnyard grass, recently, the common weeds such as sedge family, Pontederiaceae, Alismataceae such as difformed galingale herb, firefly Lin, arrowhead, Monochoria korsakowii, Monochoria vaginalis have produced resistance to sulfonylurea herbicide, make the weeding problem more complicated.2. perennial weed harm becomes major issue, and particularly the sedge family perennial weed is more outstanding.3. advanced age barnyard grass and moleplant seed the problem of preventing and kill off need solve; 4. the herbicide of weed killer herbicide kind spectrum remains to be enlarged, and extends the lasting phase that soil is prevented and kill off medicament.5. more urgent for the demand of wide spectrum, selectivity weed killer herbicide kind strong, easy to use.
Use weed killer herbicide after the seedling that penoxsuam system is developed by U.S. Tao Nongke company (Dow AgroSciences), it causes effect by inhibition acetolactate synthestase (ALS).On September 24th, 2004 is in U.S. EPA official register registration, applies in southern US rice district, registers in China in 2008 in 2005.this medicament can very effectively be prevented and kill off barnyard grass and (comprise Stam F-34, the barnyard grass of dichloro quinolinic acid and anti-acetyl-CoA carboxylase tool resistance), moleplant seed and annual sedge weed, simultaneously, it also can prevent and kill off anti-bensulfuron-methyl weeds in paddy field, and many broad-leaveds and sedge weed and barnyard grass etc. had residual activity, for present paddy field is composed the widest kind with herbicide in weed killer herbicide, but use cost is high, limiting its spread uses, therefore penoxsuam and another kind of combinations of herbicides is composite, improve drug effect, enlarge the control of weeds spectrum, reduce usage amount, enlarging using of this medicament is present urgent problem.
The English common name penoxsulam of penoxsuam, chemical name 2-(2,2-difluoro ethoxy)-N-(5,8-dimethoxy (1,2,4) triazole-(1,5-C) pyrimidine-2-base)-6-trifluoromethyl-benzene sulfanilamide (SN).Penoxsuam is a kind of triazolopyrimidine sulfonamide weed killer herbicide, works by suppressing the acetyl-lactic acid ester synzyme, and medicine conducts to meristematic tissue via grass cutting blade, sheath section or root absorption, causes weed growth to stop, and yellow is then dead.Be used for preventing and kill off the paddy field annual weed, to the barnyard grass special efficacy, but to the anti-heterodyne of part grassy weed, nutgrass flatsedge and broad leaved weed.The action target of this medicament is acetolactate synthestase (ALS), according to the hodgepodge of the anti-sulfonylurea herbicide of reported literature to the cross resistance level of triazolopyrimidine sulfonamides herbicide significantly lower than to other sulfonylurea medicaments, and the activity of weeding of penoxsuam and other ALS inhibitor have obvious difference.Therefore penoxsuam is the comparatively ideal weed killer herbicide of control paddy field weed.
The English common name bensulfuron-methyl of bensulfuron-methyl, molecular formula C
14H
13NO
7S, chemical name α-{ [(4,6-dimethoxypyridin-α-yl) amino carbonyl amino] sulfonyl methyl } methyl benzoate.Bensulfuron-methyl is a kind of selectivity inner-adsorption conduction-type herbicide.Active ingredient can be in water diffusion rapidly, for weeds root and blade absorb weeds each one of transferring to, the biosynthesis of hindered aminoacid, lysine, isoleucine stops division and the growth of cell.The susceptible weeds GF is obstructed, and tender tissue turns to be yellow too early and suppresses the growth of leaf section, hinders root growth and necrosis.It is harmless inertia chemicals that active ingredient enters the interior metabolism rapidly of paddy rice body, to rice safety.be mainly used in the direct seading rice field, the rice seedling bed, the transplanting rice field, the rice transplanting paddy field is prevented and kill off annual and perennial broadleaf weed and nutgrass flatsedge, especially good to mexicana and needle spikesedge herb texts spy, under high dose, the grassy weeds such as barnyard grass there is strong inhibition growth, to working as a stubble rice safety, without pedo relict, also very safe to succession crop, as the outstanding kind in a herbicide for paddy field single dose, advantage is a lot, but blemish in an otherwise perfect thing is without killing action to grassy weed such as barnyard grass, the Weed Resistance that causes after using for many years rises year by year, use cost is higher.
In actual use, the barnyard grass special efficacy of penoxsuam to rice field, but not satisfactory to part broad leaved weed, nutgrass flatsedge preventive effect; Bensulfuron-methyl has preventive effect preferably as a kind of herbicide for paddy field commonly used to broad leaved weed, nutgrass flatsedge, but because the resistance problem usage amount increases year by year, and to grassy weed such as barnyard grass without killing action.Therefore, penoxsuam, bensulfuron-methyl are carried out rational mixture, have the control of weeds of expansion spectrum, reduce spraying times, reduce the effect of cost accounting, to rice safety.
