Description
Technical field
The present invention relates to the herbicidal composition of a kind of cinosulfuron-containing and penoxsuam, be specifically related to a kind of weed killer herbicide for control rice field grassy weed, broad leaved weed and sedge weed, it is the active binary herbicidal composition of forming by cinosulfuron, penoxsuam.
Background technology
Large-area applications 2 from about the nineteen fifty, 4-drips, 2 first, 4 chlorine have been prevented and kill off since the paddy field broad leaved weed, paddy field develops rapidly with the weed killer herbicide kind, kind updates, perfect, successively emerge in large numbers weed killer herbicides such as diphenyl ether, thiocarbamates, amide-type, quinoline carboxylic acid, sulfonylurea, formed the comparatively perfect chemical weed control 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. the weeds resistance is outstanding, wherein comparatively outstanding to the resistance of Stam F-34, dichloro quinolinic acid, butachlor, benthiocarb with the barnyard grass grass, recently, common weeds such as sedge family, Pontederiaceae, Alismataceae such as difformed galingale herb, firefly Lin, angustifolia arrowhead herb, Monochoria korsakowii, Monochoria vaginalis have produced resistance to sulfonylurea herbicide, make the weeding problem more become complicated.2. perennial weed harm becomes major issue, and particularly the sedge family perennial weed is more outstanding.3. the careless problem of preventing and kill off with moleplant seed of barnyard grass at advanced age need solve; 4. the grass spectrum of killing of weed killer herbicide kind remains to be enlarged, and prolongs 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 behind 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 in 2005, registers in China in 2008.This medicament can very effectively be prevented and kill off barnyard grass grass (comprising the barnyard grass grass to Stam F-34, 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-sulfonylurea weeds in the paddy field, and many broad-leaveds and sedge weed and barnyard grass grass etc. had residual activity, for present paddy field is composed the widest kind with killing grass in the weed killer herbicide, but the use cost height limits its large tracts of land and promotes the use of.
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 absorbs via grass cutting blade, sheath portion or root, conducts to meristematic tissue, causes weed growth to stop, and yellow is dead then.Be used for preventing and kill off the paddy field annual weed, to barnyard grass 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), significantly be lower than other sulfonylurea medicaments according to the hodgepodge of the anti-sulfonylurea herbicide of the reported literature cross resistance level to triazolopyrimidine sulfonamides herbicide, and the activity of weeding of penoxsuam and other ALS inhibitor have evident difference.Therefore penoxsuam is the comparatively ideal weed killer herbicide of control paddy field weed.
The English common name cinosulfuron of cinosulfuron, molecular formula C
