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 the pesticidal preparations field, relate to a kind of wheat paddock Herbicidal combinations and preparation thereof specifically.
Background technology
Wheat is the general designation of Triticum plant, be a kind of the gramineous plants of 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 generalized grain crops, occupies critical role in all cereal crops, is the basic of China's agricultural.But, the most of wheat paddock of China always has crop smothering in various degree to take place, the most serious with grassy weed crop smotherings such as broad leaved weed crop smothering such as lamb's-quarters, acalypha copperleaf and lady's-grass, herba setariae viridis grass, this two classes weeds kind is many, and it is wide to distribute, growing power is vigorous, the individual plant area coverage is big, fights for moisture, nutriment, space in a large number with wheat, causes a little less than the wheat growth gesture, directly influence the yield and quality of wheat, directly influence China's cereal crops reserves.Therefore, domestic wheat paddock is extensive use of 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 the wheat paddock weeds is a Flumetsulam, and its active component is a Flumetsulam, chemical name be 2 ', 6 '-two fluoro-5-methyl (1,2,4)-triazols (1,5-a) pyrimidine-2-sulfonanilide.Flumetsulam is interior suction conductivity weed killer herbicide, and root system and blade absorption, xylem and phloem conduction by weeds accumulate in the weeds meristematic tissue, by suppressing acetolactate synthestase in the weeds body, protein synthesis is obstructed, and weeds stop growing, and finally cause death.But the broad leaved weed herbicidal effect of Flumetsulam is still not fully up to expectations.Simultaneously, its preventive effect to grassy weed is relatively poor, can not effectively prevent and treat the wheat paddock main weeds.
Summary of the invention
In view of this, the object of the invention provides a kind of wheat paddock Herbicidal combinations and preparation thereof, makes it can improve the preventive effect of broad leaved weed and grassy weed and reduces dosage.
For realizing purpose of the present invention, the present invention adopts following technical scheme:
A kind of wheat paddock Herbicidal combinations is made up 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 are that (1,5-a) pyrimidine-2-sulfonanilide belongs to triazolopyrimidine sulfonamides to 2 ', 6 '-two fluoro-5-methyl (1,2,4)-triazols, 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, under the arid situation of soil, also can reach herbicidal effect.
Tralkoxydim, chemical name are 2-[1-(ethoxy imino) propyl group]-3-hydroxyl-5-(2,4, the 6-trimethylphenyl) cyclohexene-2-ketone, belong to the 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 by Herbicidal combinations of the present invention and pesticidal preparations and form.
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 agricultural and goes up any formulation of acceptable, and the preferred formulation formulation is oil-suspending agent, water dispersible granules and wetting powder.Auxiliary material of the present invention can be made up of a kind of and surfactant in solid carrier, the 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, show activating agent can be selected from alkylsulfonate, fatty alcohol sulfonate, alkylphenol polyoxyethylene, lauryl sodium sulfate, calcium dodecyl benzene sulfonate, sodium lauryl sulfate, lignosulfonates, carboxymethyl cellulose, agricultural newborn 500#, agricultural newborn 600#, Nongru-700 #, farming breast 2201, farming breast 8209, farming breast 8312, farming breast 8210, agricultural newborn NP-10, farming breast 0425, farming breast 0408, farming breast 3517, farming breast 8220, farming 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 mix each active component of back because the difference of composition, structure, physicochemical property makes that the synergy between each active component is 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 being exactly the effect of its generation, summation action equals the sum total of each composition effect; Antagonism is meant that a kind of material disturbed the effect of another kind of material when two kinds of materials acted on living organism, or the effect of interfering with an opponent each other, the phenomenon that general effect is descended.
The test of wheat paddock control of weeds has been carried out in weed killer herbicide of the present invention and each single agent, the result shows, under the prerequisite of weed killer herbicide effective ingredient consumption of the present invention single agent effective ingredient consumption less than each, the drug effect that the present invention prevents and treats broad leaved weed and grassy weed is higher than each single agent, show that each active component does not have cross tolerance in the weed killer herbicide of the present invention, control efficiency has synergistic effect.
By above technical scheme as can be known, the weeds preventive effect of Herbicidal combinations of the present invention and preparation thereof significantly improves, and has the notable synergistic effect, and reduce the consumption of active ingredient, delay the drug-fast generation of weeds, reduce pollution, can be widely used in agriculture field environment.
