Abstract
The invention discloses a weeding composition containing thiencarbazone-methyl, pinoxaden and florasulam. The mass ratio of thiencarbazone-methyl, pinoxaden and florasulam is 1-20: 1-20: 1-20. The weeding composition possesses obvious synergic effect, and is applicable to prevent and eliminate wheat-field annual Gramineae weeds and broad-leaf weeds.
Description
Technical field
The present invention relates to agricultural chemicals Herbicidal combinations, be, azoles quinoline grand with thiophene ketone sulphur grass ester, florasulam for active ingredient, for preventing and treating farmland weed, be particularly useful for preventing and kill off wheat paddock annual gramineous weed and broad leaved weed.
Background technology
Chemical method weeding is agriculturally one of Main Means controlling weeds.In recent years, because some weed killer herbicide kind large area are used alone, a lot of weeds have been caused to develop immunity to drugs.Simultaneously, grass when weeds occur is mutually complicated, not only annual and perennial weed is mixed raw, draft, liana and shrub have concurrently, and weeds emerge uneven, seed, low age, the staggered generation of weeds at advanced age, so when weed killer herbicide kind is used alone, defect in a certain respect and limitation all can be shown.
Thiophene ketone sulphur grand (thiencarbazone-methyl) is sulfonyl-amino-carbnyl triazolinone class weed killer herbicide, is inhibitor of acetolactate synthetase.
Azoles quinoline grass ester belongs to neophyl pyrazolines weed killer herbicide, and the mechanism of action is acetyl-CoA carboxylase (ACC) inhibitor, causes fatty acid biosynthesis block, makes cell division stop cell membrane destructurized containing fat, causes weeds dead; Have Uptake and translocation, be mainly used in wheatland and prevent and kill off annual gramineous weed, through toxicity test and field control effectiveness test, result shows wheatland annual gramineous weed as wild oat, green foxtail, barnyard grass etc. have good preventive effect.
Florasulam is triazolopyrimidine sulfonamides super-high-efficient weed killer herbicide, and florasulam is inner-adsorption conduction-type herbicide, can conduct to weeds complete stool, and thus herbicide is thorough, can not recur.Efficacy stability at low temperatures, even still can ensure stable drug effect 2 DEG C time, this point is that other weed killer herbicides are incomparable.Broad leaved weed is prevented and kill off for wheat paddock.
Thiophene ketone sulphur is grand, the single use of azoles quinoline grass ester, florasulam time, all have certain defect and limitation.
The present inventor is grand to thiophene ketone sulphur, the mixture of azoles quinoline grass ester, florasulam conducts in-depth research, on the basis of a large amount of formula indoor screening tests and field medicine effect test, find that thiophene ketone sulphur is grand, azoles quinoline grass ester, florasulam carry out mixture, within the scope of certain mixed ratio, obvious synergistic effect is shown to weeds of wheat, after further study, the present invention is completed.
Thiophene ketone sulphur is grand, azoles quinoline grass ester, florasulam mixture and application there is no report at present.
Summary of the invention
The object of the invention is to solve in prior art to farmland weed develop immunity to drugs problem and actual control efficiency poor, provide a kind of efficient, low toxicity, quick-acting are good and the lasting period is long, are conducive to the Herbicidal combinations of the farmland weed comprehensive regulation.
Another object of the present invention is to provide and is used for preventing and kill off farmland weed by this Herbicidal combinations, is particularly useful for preventing and kill off wheat annual gramineous weed and broad leaved weed.
Technical solution of the present invention: a kind of Herbicidal combinations containing thiophene ketone sulphur grand and azoles quinoline grass ester and florasulam, the careless ester of, azoles quinoline grand with thiophene ketone sulphur, florasulam are for active ingredient, and grand and azoles quinoline grass ester and florasulam the mass ratio of thiophene ketone sulphur is 1 ~ 20:1 ~ 20:1 ~ 20.
Herbicidal combinations of the present invention is prepared into any one formulation being applicable to agriculturally using by known method, reasonable formulation is the one in wetting powder, suspending agent or dosage form of water dispersible granule.
The auxiliary agent used in Herbicidal combinations of the present invention comprise solvent, dispersant, stabilizing agent, emulsifier, antifreezing agent, thickener etc. and other to be of value to active ingredient stable and play the known substance of drug effect in the formulation, all various compositions that are conventional in pesticidal preparations or permission use, be not particularly limited, concrete composition and consumption are determined by simple test according to recipe requirements.
Product described in the invention can the form of finished product preparation provide, and namely in composition, each material mixes, and the composition of composition also can the form of single dose provide, and directly mixes in tank or bucket, be then diluted to required concentration before using.The frequency of administration of Herbicidal combinations of the present invention and amount of application change with weather condition and crop condition change, can by the object using suitable formulation to reach control.
Herbicidal combinations of the present invention is applicable to prevent and kill off wheat paddock annual gramineous weed and broad leaved weed.
Compared with prior art, beneficial effect of the present invention is, composite have obvious synergistic effect, improves control efficiency; Expand control spectrum; Two kinds of active ingredients are composite, reduce Pesticide use amount, thus reduce cost and decrease the pollution to environment.
