Abstract
The invention relates to the field of pesticide preparations, and discloses a wheatland weeding composition. The wheatland weeding composition comprises tralkoxydim and flumetsulam. The invention also discloses a wheatland weed killer which comprises the weeding composition and auxiliary materials acceptable in agriculture, and the weeding composition accounts for 1-85 percent by weight of the weed killer. The weed preventing effect of the weeding composition and the preparation thereof disclosed by the invention is obviously improved, the synergistic effect is obvious, the dosage of active ingredients is reduced, the generation of drug resistance of weeds is delayed, environmental pollution is reduced, and the wheatland weeding composition and the preparation thereof can be widely applied in the agricultural field.
Description
Technical field
The present invention relates to pesticidal preparations field, relate to specifically a kind of Wheat field weeding composition and preparation thereof.
Background technology
Wheat is the general designation of Triticum plant, it is a kind of gramineous plants extensively planting all over the world, being rich in starch, protein, fat, mineral matter, calcium, iron, thiamine, vitamin b3, nicotinic acid and vitamin A etc., is the cereal crops of gross yield second in the world.In China, wheat is one of Three major grain crops, occupies the basic of critical role ，Shi China agricultural in all cereal crops.But, the most of wheat paddock of China always has crop smothering in various degree to occur, the most serious with grassy weed crop smotherings such as the broad leaved weed crop smotherings such as lamb's-quarters, acalypha copperleaf and lady's-grass, herba setariae viridis grass, this two classes weeds kind is many, distributes wide, growing power is vigorous, individual plant area coverage is large, fights in a large number moisture, nutriment, space, a little less than causing wheat growth gesture with wheat, directly affect the yield and quality of wheat, directly affect China's cereal crops reserves.Therefore, domestic wheat paddock is widely used weed killer herbicide, avoids wheat because of the weeds underproduction.
At present, the domestic weed killer herbicide that is usually used in preventing and treating weeds of wheat is Flumetsulam, and its active component is Flumetsulam, chemical name be 2 ', 6 '-bis-fluoro-5-methyl (1,2,4)-triazols (1,5-a) pyrimidine-2-sulfonanilide.Flumetsulam is interior suction conductivity weed killer herbicide, by root system and blade absorption, xylem and the phloem of weeds, is conducted, and in weeds meristematic tissue, accumulates, by suppressing acetolactate synthestase in weeds body, make protein biosynthesis block, weeds stop growing, and finally cause death.But the broad leaved weed herbicidal effect of Flumetsulam is still not fully up to expectations.Meanwhile, its preventive effect to grassy weed is poor, can not effectively prevent and treat wheat paddock main weeds.
Summary of the invention
In view of this, the object of the invention is to provide a kind of Wheat field weeding composition and preparation thereof, can improve the preventive effect of broad leaved weed and grassy weed and reduce dosage.
For realizing object of the present invention, the present invention adopts following technical scheme:
A Wheat field weeding composition, is comprised of tralkoxydim and Flumetsulam.
Wherein, the mass ratio of described tralkoxydim and Flumetsulam is preferably 1: 45-60: 1, more preferably 1: 15-15: 1, most preferably be 1: 3-3: 1.
Flumetsulam, chemical name is 2 ', 6 '-bis-fluoro-5-methyl (1,2,4)-triazol (1,5-a) pyrimidine-2-sulfonanilide, belonging to triazolopyrimidine sulfonamides, is typical inhibitor of acetolactate synthetase, is the agent of a kind of low toxicity broad spectrum weeding.Flumetsulam can be prevented and kill off most of annual and perennial broadleaf weeds, as lamb's-quarters, dayflower, huge three-coloured amaranth, field thistle, Amaranthus retroflexus, recessed amaranth, acalypha copperleaf, clearvers, common vetch etc., soluble in water, in the situation that soil is more arid, also can reach herbicidal effect.
Tralkoxydim, chemical name is 2-[1-(ethoxy imino) propyl group]-3-hydroxyl-5-(2,4,6-trimethylphenyl) cyclohexene-2-ketone, belong to oximes weed killer herbicide, be applicable to wheat, barley.Mainly prevent and kill off grassy weed, to wild oat, straw, yard grass, fescue, amur foxtail, lady's-grass and herba setariae viridis grass etc. all has control efficiency.
The present invention also provides a kind of wheat paddock weed killer herbicide, can accept auxiliary material be comprised of Herbicidal combinations of the present invention and pesticidal preparations.
Wherein, the mass percent that described Herbicidal combinations accounts for described weed killer herbicide is 1-85%, is preferably 10-62%, more preferably 20%.
According to method known in those skilled in the art, the present invention can be made into the upper any formulation of acceptable of agricultural, and preferred formulation formulation is oil-suspending agent, water dispersible granules and wetting powder.Auxiliary material of the present invention can form by a kind of and surfactant in solid carrier, liquid diluent, and wherein said solid carrier, liquid diluent and surfactant are at least a kind of.According to auxiliary material known in those skilled in the art, surfactant can be selected from alkylsulfonate, fatty alcohol sulfonate, alkylphenol polyoxyethylene, lauryl sodium sulfate, calcium dodecyl benzene sulfonate, sodium lauryl sulfate, lignosulfonates, carboxymethyl cellulose, agriculture breast 500#, agriculture breast 600#, Nongru-700 #, agriculture breast 2201, agriculture breast 8209, agriculture breast 8312, agriculture breast 8210, agriculture breast NP-10, agriculture breast 0425, agriculture breast 0408, agriculture breast 3517, agriculture breast 8220, agriculture breast 8210, NNO BX LS etc.; Solid carrier can be selected from bentonite, white carbon, high clay, potter's clay, diatomite, kaolin, precipitated calcium carbonate etc.; Liquid diluent can be selected from cyclohexanone, acetone, dimethylacetylamide, methyl alcohol, methyl oleate, dimethyl sulfoxide (DMSO), water etc.
Different herbicidal activity components are mixed rear each active component due to the difference of composition, structure, physicochemical property, make the synergy between each active component be typically expressed as synergistic effect, summation action or antagonism.So-called synergistic effect is exactly the mutual synergism between different material, and the effect of its generation is greater than the sum total of each composition effect; And the effect that summation action is exactly its generation equals the sum total of each composition effect; Antagonism refers to that when two kinds of materials act on living organism, a kind of material disturbs the effect of another kind of material, or the effect of interfering with an opponent each other, the phenomenon that general effect is declined.
Weed killer herbicide of the present invention and each single dose have been carried out weeds of wheat control test, result shows, in weed killer herbicide effective ingredient consumption of the present invention, be less than under the prerequisite of each single dose effective ingredient consumption, the present invention prevents and treats the drug effect of broad leaved weed and grassy weed higher than each single dose, show that in weed killer herbicide of the present invention, each active component is without cross tolerance, control efficiency has synergistic effect.
From above technical scheme, the weeds preventive effect of Herbicidal combinations of the present invention and preparation thereof significantly improves, and has notable synergistic effect, and reduce the consumption of active ingredient, delay the generation of herbicide resistance, reduce the pollution to environment, can be widely used in agriculture field.
