Abstract
The invention discloses a weeding composition containing active components of flumetsulam and topramezone in weight ratio of 1:(30-2):1. Since the weeding mechanism of the flumetsulam is different from that of the topramezone, the weeding composition disclosed by the invention and formed by mixing the flumetsulam and the topramezone combines the advantages of two single agents and further achieves better weeding effect. Compared with single agent for use, the weeding composition has the advantages of remarkable synergism, reduced pesticide consumption, reduced cost and high safety; a herbicidal spectrum is broadened; the weeding composition has better control effect for broad leaved weeds, cyperaceae weeds and grassy weeds; meanwhile, the pesticide resistance of the single agents can be relieved.
Description
Technical field
The present invention relates to a kind of weed killer herbicide that is used to prevent and kill off the corn weeds in field, be specifically related to a kind of Herbicidal combinations that contains Flumetsulam and benzene azoles humulone, belong to technical field of pesticide.
Background technology
In recent years, 2%, 2010 year national maize sown area of the average annual increase of Chinese maize cultivated area is about 3,000 ten thousand hectares, is the second largest crops that are only second to paddy rice.How to control the corn field crop smothering with new high-efficiency environment friendly agricultural chemicals, be a major challenge that current plant protection interface is faced.
Flumetsulam has another name called Flumetsulam, and chemistry is by name 2 ', 6 '-two fluoro-5-methyl (1,2,4)-triazols (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.Can prevent and kill off most of annual and perennial broadleaf weeds; Children grassy weed in age also there is inhibitory action; As piemarker, lamb's-quarters, chickweed, tattooing flower are harvested, preventive effects such as clearvers, Mandala, Amaranthus retroflexus, pineapple weed, corn radish are excellent; To knotweed, summer cypress, black nightshade, white dead nettle, Veronica, multiple cruciferous weeds such as flowerofanhour root or herb, Siberian cocklebur and elegance and talent dish, penny cress also have significant preventive effect, and green foxtail, Chufa are had good activity.Long, broad weed-killing spectrum of the longevity of residure, soil, cauline leaf handle all can, to soybean, corn and wheat high safety, then very responsive to rape, sweet Lay, cotton and vegetables etc.But relatively poor to part grass family and sedge weed effect, use cost is high, limits it and promotes the use of.
Benzene azoles humulone, chemistry [3-(4,5-dihydro-3-isoxazolyl)-4-sulfonyloxy methyl-2-methylbenzene]-5-hydroxyl-1-methyl isophthalic acid H pyrazoles-4-yl by name) ketone.Belong to the sulfonylurea corn field herbicide, suppress HPPD, carotenoid, chlorophyllous biosynthesis are suppressed, the susceptible weeds that causes death and germinate.Be that cauline leaf is handled weed killer herbicide behind the seedling, herbicidal spectrum is wide, and high activity is to the corn high safety.Can effectively prevent and kill off corn field annual gramineae and broad leaved weed, sedge weed, particularly can effectively prevent and kill off not good green foxtail, lady's-grass, the eleusine indica of nitre sulphur humulone preventive effect, can be used for all types of corns.But exist independent use cost high, be unfavorable for that large tracts of land promotes the use of.
In actual use, Flumetsulam can be prevented and kill off most of annual and perennial broadleaf weeds, but relatively poor to grass family and sedge weed effect; Benzene azoles humulone has preventive effect preferably to annual gramineae and broad leaved weed, sedge weed, but invalid to the part broad leaved weed.
Summary of the invention
The object of the present invention is to provide that a kind of component is reasonable, herbicidal spectrum is wide, preventive effect is good, contain the Herbicidal combinations of Flumetsulam and benzene azoles humulone cheaply; Be used for preventing and kill off the various weeds of corn field, the application in preventing and kill off corn field in broad leaved weed, sedge weed and the grassy weed all has remarkable result.
Herbicidal combinations of the present invention includes weight ratio and is 1: 30～20: 1 active component Flumetsulam and benzene azoles humulone.
Be added with the agriculture acceptable carrier of going up in the composition of the present invention and process upward common formulations of agricultural; Wherein, The cumulant of Flumetsulam and benzene azoles humulone accounts for 1～85% of Herbicidal combinations gross weight; Preferably, the cumulant of Flumetsulam and benzene azoles humulone accounts for 4～50% of Herbicidal combinations gross weight.
According to method known in those skilled in the art; The present invention can be made into agricultural and goes up the various formulations of acceptable; Comprise oil-suspending agent, missible oil, water dispersible granules, wetting powder etc.; Preferably, be added with the agriculture acceptable surfactant and solid carrier or liquid diluent gone up in the composition of the present invention and process oil-suspending agent or water dispersible granules; Described surfactant, solid carrier, liquid diluent are auxiliary material carrier commonly used on the agriculture preparation; Wherein, said surfactant can be alkylsulfonate, fatty alcohol sulfonate, APES, JFC (AEO), lauryl sodium sulfate, calcium dodecyl benzene sulfonate, 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 etc.; Solid carrier can be bentonite, white carbon, high clay, kaolin, gelatin, potter's clay, diatomite, precipitated calcium carbonate etc.; Liquid diluent can be cyclohexanone, acetone, dimethylacetylamide, methyl alcohol, methyl oleate, dimethyl sulfoxide (DMSO), water etc.
The application of Herbicidal combinations of the present invention in preventing and kill off the corn weeds in field.
The inventor is through discovering; Flumetsulam and benzene azoles humulone rationally are mixed, can overcome single preparation defective and have remarkable synergy, expansion weeds spectrum, a dispenser can be prevented and kill off corn field overwhelming majority weeds; Reduce spraying times; Reduce the control cost, slow down pesticide resistance, corn safety.
Herbicidal combinations of the present invention is because flumetsulam is different with benzene azoles humulone weeding mechanism; Composite back combines the advantage of two kinds of single agent, has reached better herbicidal effect, uses with respect to single agent to have obvious synergistic effect; Reduce dosage, reduced cost and safer; Enlarged killing the grass spectrum, broad leaved weed, sedge weed and grassy weed have all been had better control efficiency; Can slow down simultaneously pesticide resistance because of using single agent to produce.
