Abstract
The invention discloses a pesticide composition containing thiencarbazone-methyl, clodinafop-propargyl and mesosulfuron. The effective ingredients of the pesticide composition comprise the thiencarbazone-methyl, the clodinafop-propargyl and the mesosulfuron, wherein the weight percent of the thiencarbazone-methyl in the pesticide composition is 1%-20%; the weight percent of the clodinafop-propargyl in the pesticide composition is 1%-20%; the weight percent of the mesosulfuron in the pesticide composition is 1%-20%; and the rest is pesticide auxiliaries. After the thiencarbazone-methyl, the clodinafop-propargyl and the mesosulfuron are compounded, the obvious synergism is achieved; compared with the dosage of the singly used effective ingredients, the dosage of the effective ingredients of the compound medicament is obviously lowered; and the pesticide composition is fit for preventing and killing the annual weeds in a wheat paddock.
Description
Technical field
The composition pesticide that the present invention relates to, be, clodinafop-propargyl grand with thiophene ketone sulphur and mesosulfuron 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.
Thiophene ketone sulphur is grand is sulfonyl-amino-carbnyl triazolinone class weed killer herbicide, is inhibitor of acetolactate synthetase.Thiophene ketone sulphur is grand is can effectively prevent and kill off wheat paddock grassy weed and broad leaved weed, and this active ingredient effectively can prevent and kill off piemarker and many Caryophyllaceae weeds, all can use in early days before bud and after bud.Safener accelerates the degraded of this weed killer herbicide in cereal, improves the tolerance of crop.
Mesosulfuron is sulfonylurea herbicide, main chirp is absorbed by the cauline leaf of plant, through phloem and xylem conduction, pass through soil absorption on a small quantity, suppress the activity of the acetolactate synthestase in sensitive plant body, cause the biosynthesis block of the numerous acid of side chain ammonia, thus T suppression cell division, cause sensitive plant dead.Generally, dispenser is after 2 ~ 4 hours, and the absorptive amount of susceptible weeds peaks, and stops growing after 2 days, and within 4 ~ 7 days, rear blade starts yellow, occurs withered spot subsequently, dead after 2 ~ 4 weeks.The safener contained in this product, can promote that it is doing to decompose rapidly in object, and does not affect its degraded in target weeds body, thus reaches the object of killing weeds, cover crop.Be applicable to use in soft and semi-rigid type winter wheat variety.Amur foxtail, wild oat, caput grass, annual bluegrass, hard grass, alkali thatch, Annual Ryegrass, lolium temulentum, bromegrass, candle grass, Triticum tauschii, Tong grass, wheatgrass, shepherd's purse, amur foxtail, green foxtail, spontaneous rape etc. can be prevented and kill off.
Clodinafop-propargyl belongs to neophyl pyrazolines weed killer herbicide, and the mechanism of action is acetyl-CoA carboxylase (ACC) inhibitor.Cause fatty acid biosynthesis block, make cell division stop cell membrane destructurized containing fat, cause weeds dead.Have Uptake and translocation to be mainly used in barley field and to prevent and kill off annual gramineous weed, through toxicity test and field control effectiveness test, result shows barley field annual gramineous weed as wild oat, green foxtail, barnyard grass etc. have good preventive effect.
Thiophene ketone sulphur is grand, clodinafop-propargyl and mesosulfuron single use time, all have certain defect and limitation.
The present inventor conducts in-depth research grand, clodinafop-propargyl, mesosulfuron the mixture of thiophene ketone sulphur, on the basis of a large amount of formula indoor screening tests and field medicine effect test, find that thiophene ketone sulphur is grand, clodinafop-propargyl, mesosulfuron 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, the mixture of clodinafop-propargyl, mesosulfuron 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 composition pesticide of the farmland weed comprehensive regulation.
Another object of the present invention is used for preventing and kill off farmland weed by this composition pesticide, is particularly useful for preventing and kill off wheat paddock annual weed etc.
A composition pesticide containing the grand and clodinafop-propargyl of thiophene ketone sulphur and mesosulfuron, active ingredient is that thiophene ketone sulphur is grand, clodinafop-propargyl, mesosulfuron; The grand percentage by weight in the composition of thiophene ketone sulphur is 1% ~ 20%, and clodinafop-propargyl percentage by weight is in the composition 1% ~ 20%, and mesosulfuron percentage by weight is in the composition 1% ~ 20%, and all the other are insecticides adjuvant.
Composition pesticide of the present invention is prepared into any one formulation being applicable to agriculturally using by known method, reasonable formulation is wetting powder, suspending agent or water dispersible granules.
The auxiliary agent used in composition pesticide 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.
Composition pesticide 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.
