Abstract
The invention discloses a pesticide composition containing flucarbazone, isoproturon and florasulam, and an application thereof. The active components of the pesticide composition contain flucarbazone, isoproturon and florasulam according to a mass ratio of 0.5-5:10-80:0.1-3. The pesticide composition has obvious synergism in above ratio range, reduces the use dosage of pesticides, reduces the pesticide use frequency, reduces the pesticide use cost, and reduces untoward influences of pesticides on the ecologic environment; the pesticide composition enlarges the weeding spectrum, solves various weed problems through one-time pesticide application, and makes up the defects and restriction in the use process of single doses; the composition prolongs the service life of medicines, and is of important significance to comprehensively control the resistance of weeds; and the pesticide composition also has the advantages of rapid pesticide effect performance, long persistent period, and low use cost, and can be used to control the gramineous weeds and parts of broad leaved weeds in wheat fields.
Description
Technical field
The invention belongs to technical field of pesticide, being specifically related to a kind of composition pesticide containing flucarbazone, isoproturon and florasulam for preventing and kill off wheat paddock grassy weed, broad leaved weed.
Background technology
According to statistics world's cereal produce annual due to illness, worm, crop smothering loss 14%, the loss that wherein crop smothering causes is about 11%, and Weed infestation is the key factor of restriction crop yield.The use of chemical herbicide is one of important symbol of agricultural modernization.In recent years, the sales volume of weed killer herbicide increases year by year, and the proportion accounting for agricultural chemicals sales volume increases year by year, uses area and expands year by year.Wheat is the crops that Consumption of China amount is maximum, cultivated area is maximum, gross yield is maximum, per unit area yield is the highest, has consequence in the world.But the serious of wheat crop smothering is the major obstacle restricting its high yield, stable yields.Current wheat weeds is prevented and kill off mainly based on cauline leaf spraying after weeds seedling, and weed killer herbicide kind is based on acetyl-CoA carboxylase inhibitor class.The continuous Long-Time Service of single herbicide causes herbicide resistance obvious, and the weeds such as wheatland Alopecurus, amur foxtail, Wang grass, ox chickweed, shepherd's purse all create obvious resistance to multiple weed killer herbicide.Early application after exploring wheat weeds seedling, effectively prevent and kill off resistance, efficient, the safety herbicide of malignant weed seem particularly important.
Flucarbazone, chemical name: N-(2-Trifluoromethoxyphen-l sulfonyl)-4,5-bis-chloro-3-methoxyl group-4-methyl-5-oxygen-1H-1,2,4-formamidetriazole sodium salt.Belong to sulfonylurea herbicide, absorbing mainly through root and cauline leaf the reaction suppressing the predecessor acetolactate synthestase producing side chain amino acid, leucine, isoleucine and knot propylhomoserin, is cauline leaf process weed killer herbicide after selectivity seedling.Flucarbazone is efficient, broad-spectrum herbicide, can be applicable to prevent and kill off grass family and some important broad leaved weedses in wheat paddock, to second stubble crop safety.
Isoproturon, chemical name: N-(2-Trifluoromethoxyphen-l sulfonyl)-4,5-bis-chloro-3-methoxyl group-4-methyl-5-oxygen-1H-1,2,4-formamidetriazole sodium salt.Belong to sulfonylurea herbicide, absorbing mainly through root and cauline leaf the reaction suppressing the predecessor acetolactate synthestase producing side chain amino acid, leucine, isoleucine and knot propylhomoserin, is cauline leaf process weed killer herbicide after selectivity seedling.Isoproturon is efficient, broad-spectrum herbicide, can be applicable to prevent and kill off grass family and some important broad leaved weedses in wheat paddock, to second stubble crop safety.
Florasulam, chemical name: 2 ', 6 '-two fluoro-5-methoxyl group-8-fluorine [1,2,4] triazol [1,5-c] pyrimidine-2-sulfonanilide.Belong to triazolopyrimidine sulfonamides herbicide, absorb by weeds root and leaf, conduct in plant body, suppress acetolactate synthase activity, thus cause weeds to stop growing, dead.Florasulam effectively can prevent and kill off winter wheat, corn field broad leaved weed.
Patent flucarbazone isoproturon (application number: 201210011487.4) be background information is had according to isoproturon, flucarbazone isoproturon to wheatland grass family and part broad leaved weed cauline leaf treatment effect outstanding, but it is poor to part broad leaved weed effect, flucarbazone isoproturon florasulam has outstanding cauline leaf process to wheatland grass family and broad leaved weed, expand herbicide spectrum, a drug solves wheat Weed infestation, has saving of labor, labour-saving advantage.
Summary of the invention
Goal of the invention: in prior art to farmland weed develop immunity to drugs problem, single use control efficiency poor, once use the problem being difficult to effectively to control Weed infestation in wheat whole breeding time, the object of this invention is to provide a kind of composition pesticide containing flucarbazone, isoproturon and florasulam, make it have efficient, wide spectrum, environmentally friendly, be beneficial to the features such as the wheat weeds comprehensive regulation.Another object of the present invention is to provide a kind of application of the above-mentioned composition pesticide containing flucarbazone, isoproturon and florasulam.
Technical scheme: in order to realize foregoing invention object, the technical solution used in the present invention is:
Containing a composition pesticide for flucarbazone, isoproturon and florasulam, active ingredient is flucarbazone, isoproturon and florasulam, and the mass ratio of flucarbazone, isoproturon and florasulam is 0.5-5: 10-80: 0.1-3.
The preferred mass ratio of flucarbazone, isoproturon and florasulam is 1: 26: 0.5,1: 25: 0.5,1: 27: 1,2: 25: 0.4 or 2: 40: 0.9.
