Description
Technical field
The present invention relates to agricultural herbicide technical field, be specifically related to a kind of novel wheat paddock weed killer herbicide.
Background technology
3.5 hundred million mu of wheat areas are planted throughout the year by China, are only second to paddy rice.Wheat, from after planting endangered by various broad leaved weeds to results, mainly contains common sow thistle, annual fleabane herb, field thistle, chickweed, ox chickweed, Siberian cocklebur, corn gromwell, common vetch, hairy tare, shepherd's purse, Hairy Bittercress, Veronica, Carolina Cranesbill Herb etc.Be subject to the multiple Effects of Factors such as climate, soil property, cropping system, wheat weeds group and generation quantity difference between interzone, field are large.Chemical control wheat weeds is the most effective means.According to inventor, in recent years in the main growing area investigation of wheat, find Hebei Province shepherd's purse, broadcast ma wormwood artemisia, the clearvers in Henan, the ox chickweed in Jiangsu, chickweed, the field bindweed of Xinjiang, Gansu, Ningxia, China occurs serious, and resistance is serious.
Affect the main weeds of wheat yield, wheat paddock main weeds has: broadcast ma wormwood artemisia, lamb's-quarters, shepherd's purse, corn gromwell, conical silene herb, Veronica, field thistle, clearvers, chickweed, common vetch, amur foxtail, wild oat, Triticum tauschii, bromegrass, Wang grass etc.The weed killer herbicide of the management of weeds that current wheat paddock is main is 2.4 d butyl esters, florasulam etc., and due to long-term use, resistance improves, and causes dosage large, and environmental pollution, has also increased peasant's dispenser cost.

Beneficial effect of the present invention:
Wheat paddock weed killer herbicide herbicidal effect provided by the invention is good, and drug cost is low, good to crop safety.
Embodiment
The invention provides a kind of novel wheat paddock weed killer herbicide, it comprises florasulam, flucarbazone, fenoxaprop, tribenuron-methyl, clopyralid, surfactant and carrier.
Florasulam chemical name is 2 ', 6 '-bis-fluoro-5-ethyoxyl-8-fluorine [1,2,4] triazoles [1,5-C] pyrimidine-2-sulfonanilides, molecular formula is C12H8F3N503S, molecular weight is 359.28.Florasulam is triazolopyrimidine sulfonamides super-high-efficient weed killer herbicide, and wheat crops is had to high selectivity, is applicable to wheat paddock and prevents and kill off broad leaved weed.Florasulam is inner-adsorption conduction-type herbicide, can conduct to weeds complete stool, thereby herbicide is thorough, can not recur.And efficacy stability at low temperatures, even still can guarantee to stablize drug effect in the time of 2 ℃, this point is that other weed killer herbicides are incomparable.
Flucarbazone, has another name called young tiger tiger, English name: Flucarbazone-Na, chemical name: 1H-1,2,4-triazole-1-carbamyl-4,5-2H-3-methoxyl group-4-methyl-5-O-N-[[2-(trifluoro methoxy) benzene] sulphonyl]-sodium salt.Flucarbazone is the efficient wheat paddock weed killer herbicide of sulfonylurea internal-suction type, and its active ingredient can be absorbed by the root of weeds and cauline leaf, by suppressing the activity of acetolactate synthestase in weeds body, destroys the normal Physiological and Biochemical Metabolism of weeds and brings into play activity of weeding.The grassy weeds such as bromegrass, wild oat are had to obvious preventive effect, multiple broadleaf weed is had to control action.
Fenoxaprop, chemical name is: (R)-2-[4-(6-chloro-1,3-benzoxazole-2-base oxygen) phenoxy propionic acid ethyl ester, molecular formula: C18H16CIN05 molecular weight is 361.78, is selective post-emergence herbicide.Add safener cloquitocet_mexyl, be mainly used in the annual gramineous weed that wheat paddock is prevented and kill off.To wheat safety.Being cauline leaf inorganic agent after seedling, is the important new varieties of wheat paddock weed killer herbicide.Be mainly used in Control Wild oat, amur foxtail, green foxtail, oat, perennial ryegrass, annual bluegrass, barnyard grass, spontaneous corn, lady's-grass etc.
The English common name tribenuron-methyl of tribenuron-methyl, molecular formula C15H17N506S, chemical name 2-[4-methoxyl group-6-methyl isophthalic acid, 3,5-triazine-2-base (methyl) carbamyl amino-sulfonyl] benzoic acid or methyl esters.Tribenuron-methyl is selective herbicide after sulfonylurea inner sucting conduction type bud.Cauline leaf can be by the root absorption of weeds cauline leaf after processing, and conduction in vivo, by hindering acetolactate synthestase, makes the biosynthesis of valine, isoleucine suppressed, stops cell division, causes weeds dead.Broadleaf weed chickweed, shepherd's purse, conical silene herb, corn gromwell, ion grass, clearvers, Hairy Bittercress, tongue of sparrow grass, volume stem knotweed etc. are responsive to tribenuron-methyl, the medium sensitivities such as wartwort, Veronica.
Clopyralid (clopyralid), chemical name: 3,6-dichloropyridine-2-carboxylic acid, clopyralid is a kind of pyridines weed killer herbicide, after weeds dispenser, by blade or root absorption, in plant corpus, divide a word with a hyphen at the end of a line up and down, pass to rapidly whole plant, the mechanism of action of its herbicide is for promoting the formation of plant nucleic acid, produce excessive ribonucleic, cause root growth excessive, stem and leaf growth deformity, nutrient consumption, vascular bundle transporting function is obstructed, and causes weeds dead.Be applicable to wheat, corn field, can effectively prevent and kill off composite family, pulse family, Solanaceae and Umbelliferae weeds.Clopyralid is selective in gramineous crop, at multiple broad leaf crop, comprises in Brassic beet and other beet crops, flax, strawberry and allium crop also having same selectivity.Its broad weed-killing spectrum, can prevent and kill off annual weed and dark root perennial weed effectively.
Wherein, described carrier comprises a kind of in kaolin, precipitated calcium carbonate, clay, white carbon.
Wherein, described surfactant is alkylphenol polyoxyethylene or its phosphate, fatty alcohol-polyoxyethylene ether, one or more in lignosulfonates, naphthalenesulfonate formaldehyde condensation compound.
Wherein, the weight portion of described each component is respectively florasulam 6 weight portion～10 weight portions, flucarbazone 3 weight portion～6 weight portion, fenoxaprop 5 weight portion～10 weight portions, tribenuron-methyl 6 weight portion～10 weight portions, clopyralid 10 weight portion～15 weight portions, surfactant 1 weight portion～5 weight portion and carrier 50 weight portion～80 weight portions.
Further preferably, the weight portion of described each component is respectively florasulam 8 weight portions, flucarbazone 5 weight portion, fenoxaprop 8 weight portions, tribenuron-methyl 8 weight portions, clopyralid 12 weight portions, surfactant 3 weight portions and carrier 70 weight portions.
Weed killer herbicide prepared by the present invention is wettable powder, and its preparation method, for said components is mixed, is crossed 300 mesh sieves after air-flow crushing.
Below adopt embodiment to describe embodiments of the present invention in detail, to the present invention, how application technology means solve technical problem whereby, and the implementation procedure of reaching technique effect can fully understand and implement according to this.
