Abstract
The invention relates to the field of pesticide preparations, and discloses a herbicide composition. The herbicide composition consists of amidosulfuron and flumetsulam. The invention also disclose a herbicide which consists of the herbicide composition and auxiliary materials which can be accepted in the pesticide preparations; the herbicide composition accounts for 1 to 85 percent based on the mass of the herbicide; the control effects of the herbicide composition and the herbicide of the herbicide composition on broadleaves in a corn field and wheat land are improved obviously, and the herbicide composition and the herbicide thereof have obvious synergistic effects, the using amount of active ingredients is reduced, the pesticide resistance of weeds can be delayed, pollution to environment is reduced and the herbicide composition can be widely applied to the agriculture field.
Description
Technical field
The present invention relates to pesticidal preparations field, relate to specifically a kind of Herbicidal combinations and preparation thereof.
Background technology
Corn and wheat are the large important cereal crops of China two.Wherein, maize sown area increases by 2% every year, to national maize sown area in 2010, reaches 3,000 ten thousand hectares of left and right, is the second largest crops that are only second to paddy rice; Wheat is 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, is the basic of China's agricultural.But, the most of corn field of China and wheat paddock always have crop smothering in various degree to occur, the most serious with broad leaved weed crop smotherings such as lamb's-quarters, clearvers, ox chickweed, dayflower, huge three-coloured amaranth, field thistles, broad leaved weed kind is many, distributes wide, and growing power is vigorous, individual plant area coverage is large, fight in a large number moisture, nutriment, space with corn and wheat, a little less than causing corn and wheat growth gesture, directly affect the yield and quality of corn and wheat.Therefore, domestic corn and wheat paddock are widely used weed killer herbicide, avoid corn and wheat because of the weeds underproduction.
At present, the domestic weed killer herbicide that is usually used in control of maize field and wheat paddock broad leaved weed 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 herbicidal effect of single use Flumetsulam is still not fully up to expectations.In addition,, during Flumetsulam large usage quantity, some succession crops of corn and wheat are had to residual poisoning impact.
Summary of the invention
In view of this, the object of the invention is to provide a kind of Herbicidal combinations and preparation thereof, can improve the preventive effect of corn field and wheat paddock broad leaved weed and reduce dosage.
For realizing object of the present invention, the present invention adopts following technical scheme:
A Herbicidal combinations, is comprised of amidosulfuron and Flumetsulam.
Wherein, the mass ratio of described amidosulfuron and Flumetsulam is preferably 1: 30-40: 1, more preferably 1: 8-8: 1, most preferably be 1: 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.
Amidosulfuron, chemical name is 1-(4,6-dimethoxypyridin-2-yl)-3-mesyl (methyl) amino-sulfonyl urea, is a kind of inhibitor of acetolactate synthetase.Amidosulfuron absorbs by weeds root and leaf, in plant body, conduct, weeds stop growing, leaf look chlorisis, then withered, can effectively prevent and kill off multiple pernicious broad leaved weed as clearvers, broadcast ma wormwood artemisia, shepherd's purse Lay, amaranth, corn sow thistle, field bindweed, pepper grass, corn radish, Ben Shi knotweed, curly dock etc.Herbicidal effect after amidosulfuron dispenser is not subject to weather effect, effect stability.Again because of its in crop rapidly metabolism be harmless object, therefore to corn and succession crop safety, low toxicity, low-residual, environmentally friendly.
The present invention also provides a kind of 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 18-70%, more preferably 50%.
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 corn field and wheat paddock broad leaved weed 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 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, Herbicidal combinations of the present invention and preparation thereof significantly improve corn field and wheat paddock broad leaved weed preventive effect, there is notable synergistic effect, and reduce the consumption of active ingredient, delay the generation of herbicide resistance, the pollution of minimizing to environment, can be widely used in agriculture field.
