Abstract
The invention discloses a weeding combination containing halauxifen-methyl and thiencarbazone-methyl. The weeding combination is prepared from common auxiliaries, halauxifen-methyl and thiencarbazone-methyl, the mass part ratio of halauxifen-methyl to thiencarbazone-methyl is 10:1-1:10, the total mass percentage of halauxifen-methyl and thiencarbazone-methyl in the weeding combination is 1-80%; after halauxifen-methyl and thiencarbazone-methyl are mixed, an obvious synergistic effect is achieved, the using component of effective components of the complex pesticide is remarkably reduced compared with independent using amount, and the weeding combination is suitable for preventing and removing annual weeds of wheat fields.
Description
Technical field
The Herbicidal combinations that the present invention relates to, be with fluorine chloropyridine ester and thiophene ketone sulphur grand for active ingredient, for preventing and treating farmland weed, be particularly useful for preventing and kill off wheat paddock annual weed etc.
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.
Fluorine chloropyridine ester is a kind of active component researched and developed by the agriculture of Tao Shi benefit, can be used as pyridine carboxylic acid class weed killer herbicide, the ISO common name of this active component got the Green Light in November, 2012, the agriculture of Tao Shi benefit has carried out the market development for the methyl esters fluorine chloropyridine ester of this compound, release, for broad leaved weed prevention and control after bud in Canadian cereal market; Weed killer herbicide containing fluorine chloropyridine ester is by preventing and kill off partial resistance weeds, and such as clearvers, chickweed and cannabis weeds carry out resistance management.In addition, fluorine chloropyridine ester, by microorganism fast degradation in the environment, is planted for succeeding crop and is provided larger flexibility.
The grand a kind of sulfonyl-amino-carbnyl triazolinone class weed killer herbicide for Bayer exploitation of thiophene ketone sulphur, it is inhibitor of acetolactate synthetase, disposable dispenser can be carried out after spring wheat is emerged, dosage is 50 grams of (active ingredient)/hectares, the safety interval (PHI) of blade is 7 days, and the safety interval (PHI) of wheat and straw is 60 days.
When fluorine chloropyridine ester and the grand single use of thiophene ketone sulphur, all there are certain defect and limitation.
The present inventor conducts in-depth research fluorine chloropyridine ester and the grand mixture of thiophene ketone sulphur, on the basis of a large amount of formula indoor screening tests and field medicine effect test, find fluorine chloropyridine ester and thiophene ketone sulphur is grand carries 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.
Fluorine chloropyridine ester and the grand mixture of thiophene ketone sulphur 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 used for preventing and kill off farmland weed by this Herbicidal combinations, is particularly useful for preventing and kill off wheat paddock annual weed etc.
Technical solution of the present invention: a kind of containing fluorine chloropyridine ester and the grand Herbicidal combinations of thiophene ketone sulphur, comprise usual auxiliaries, fluorine chloropyridine ester and thiophene ketone sulphur grand, fluorine chloropyridine ester and the grand ratio of quality and the number of copies of thiophene ketone sulphur are 10:1 ~ 1:10, fluorine chloropyridine ester and the grand gross mass percentage composition in Herbicidal combinations of thiophene ketone sulphur are 1% ~ 80%, and all the other are the auxiliary agent that agriculturally can accept and allow to use.
Further, fluorine chloropyridine ester and the grand preferred mass portion rate of thiophene ketone sulphur are 1:1.
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, dosage form of water dispersible granule, and in preparation, active ingredient total content is 1% ~ 80%.
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 the present composition 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 treat annual weed, especially wheat paddock annual 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.
Embodiment
In order to make object of the present invention, technical scheme and advantage more short and sweet, the following specific embodiment of the present invention is described, but the present invention is only limitted to absolutely not these examples.The following stated is only the good embodiment of the present invention, only for describing the present invention, can not be interpreted as the restriction to scope of the present invention.It should be pointed out that all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
