Abstract
The invention discloses a mixed weeding composition containing acifluorfen and flumetsulam. The weeding composition is prepared from the following main effective components: acifluorfen and flumetsulam at the mass ratio of (1-99) to (1-99). The composition disclosed by the invention can be added with different surfactants, thickeners, solvents or solid fillers and the like, and can be processed into a plurality of dosage forms, namely missible oil, a suspending agent, an emulsion in water, wettable powder, dry suspension, a water dispersible granule and wettable powder. The weeding composition is capable of preventing and removing grassy weeds, broadleaf weeds and cyperaceous weeds of a paddy field, compared with single dosage, under the premise of improving pesticide effect, the resistance of weed is delayed, the weed control spectrum is wide, the lasting period is long, and the mixed weeding composition is safe to rice and next-stubble crops, and is an ideal paddy field weed killer.
Description
Technical field
The invention belongs to pesticide field, especially weed killer herbicide field, relate to the mixed herbicidal composite of acifluorfen and Flumetsulam.This Herbicidal combinations can apply paddy field postemergence weed control.
Background technology
Acifluorfen, has another name called weeds clean, the wealthy water purification agent of beans; , chemical name: 5-(2-chloro-α, α, α-three is fluoro-to toloxyl)-2-nitrobenzoic acid.Be a kind of contact killing type selective post-emergence herbicide, can be absorbed by weeds cauline leaf, not by root absorption in soil, and easily be decomposed by the microorganisms, therefore can not soil treatment be made, use rice direct-seeding Tanaka.Its structural formula is as follows:
Flumetsulam, chemical name: N-(2,6-difluorophenyl)-5-methyl isophthalic acid, 2,4-triazol [1,5-a] pyrimidine-2-sulfonamide; The fluoro-5-methyl of 2', 6'-bis-(1,2,4)-triazol (1,5-a) pyrimidine-2-sulfonanilide, structural formula is:
Flumetsulam belongs to triazolopyrimidine sulfonamides, is typical inhibitor of acetolactate synthetase.By suppressing the synthesis of branched-chain amino acid to make protein biosynthesis block, plant stops growing.Longevity of residure length, broad weed-killing spectrum, soil, cauline leaf process.
At present, herbicide for paddy field limit by crop safety, herbicide spectrum is also limited, be used alone the generation that a kind of weed killer herbicide single dose can not control paddy field weed completely effectively, moreover weed killer herbicide consumption is excessive or the uneven residual hazard also easily caused this season crop or succession crop of dispenser.Therefore, the present invention selects the acifluorfen of pluses and minuses complementation and Flumetsulam to be made into combination agent use, so both decrease the consumption of medicament, significantly improve herbicidal effect, it also avoid and poisoning and the possibility to succession crop generation residual hazard are produced to this season crop.
Summary of the invention
The present invention is according to the present situation of current paddy field herbicide after seedling, and after paddy field seedling weeds a situation arises, there is provided a kind of by acifluorfen and the composite two end number mixing Herbicidal combinations of Flumetsulam, this Herbicidal combinations can not only improve the preventive effect to weeds, and to when stubble and succession crop safety, reduce the drug cost of peasant simultaneously.
For achieving the above object, the technical solution used in the present invention is as follows:
A Herbicidal combinations for acifluorfen and Flumetsulam, this Herbicidal combinations is with acifluorfen and Flumetsulam for active ingredient, and the mass ratio of acifluorfen and Flumetsulam is 1:99 ~ 99:1.
Preferably, described acifluorfen and the Herbicidal combinations of Flumetsulam, the mass ratio of acifluorfen and Flumetsulam is 1: 50 ~ 50:1.
Preferably, described acifluorfen and the Herbicidal combinations of Flumetsulam, is characterized in that, the mass ratio of acifluorfen and Flumetsulam is 1:30 ~ 30:1.
The Herbicidal combinations of preferred described acifluorfen and Flumetsulam, it is characterized in that, the mass ratio of acifluorfen and Flumetsulam is 1:15 ~ 10: 1.
Described acifluorfen and the Herbicidal combinations of Flumetsulam, both acifluorfen and the Flumetsulam mass percentage in Herbicidal combinations is 1 ~ 85%.
Preferably, described acifluorfen and the Herbicidal combinations of Flumetsulam, both acifluorfen and the Flumetsulam mass percentage in Herbicidal combinations is 10 ~ 80%.
Described acifluorfen and the Herbicidal combinations of Flumetsulam, with acifluorfen and Flumetsulam for the auxiliary agent that active ingredient and agricultural chemicals allow is mixed with any one formulation.
Described acifluorfen and the Herbicidal combinations of Flumetsulam, described formulation is wetting powder, water dispersible granules, missible oil or suspending agent.
Described acifluorfen and the Herbicidal combinations of Flumetsulam, be applied to the application in the weed killer herbicide of paddy field postemergence weed control.
Described acifluorfen and the Herbicidal combinations of Flumetsulam, preparing the application of preventing and kill off in the weed killer herbicide of annual gramineous weed in paddy field, broad leaved weed and sedge weed.
Acifluorfen is a kind of contact killing type selective post-emergence herbicide, can be absorbed by weeds cauline leaf, uses acifluorfen and seedling may be caused to burn, turn yellow, and high warm purgative evil increases the weight of, but slight poisoning, can recover normal after several days; Flumetsulam belongs to triazolopyrimidine sulfonamides, is typical inhibitor of acetolactate synthetase, and by suppressing the synthesis of branched-chain amino acid to make protein biosynthesis block, plant stops growing, longevity of residure length, broad weed-killing spectrum, but it is slow to take effect.Both are made into combination agent and use, and so both decrease the consumption of medicament, significantly improve herbicidal effect, it also avoid and produce poisoning and the possibility to succession crop generation residual hazard to this season crop.
In the binary built preparation of acifluorfen of the present invention and Flumetsulam, except two kinds of active ingredients, the auxiliary agent that the agricultural chemicals such as different surfaces activating agent, thickener, solvent or solid packing allow can also be added, the multiple formulations such as missible oil, suspending agent, water dispersion granule, wetting powder can be processed into.
This Herbicidal combinations relative to single dose under the prerequisite that improve drug effect, can delay Weed Resistance, and herbicidal spectrum is wide, and the lasting period is long, enough prevents and kill off paddy field annual gramineous weed, broad leaved weed and sedge weed, and to paddy rice and second stubble crop safety.Herbicidal combinations of the present invention can be used for the weed killer herbicide preparing paddy field postemergence weed control, can be used in especially preparing the weed killer herbicide preventing and kill off various annual weed and perennial weed, especially can prepare the weed killer herbicide preventing and kill off grassy weed, broad leaved weed and sedge weed.
Herbicidal combinations of the present invention has the following advantages:
1, activity of weeding is high.Herbicidal combinations of the present invention can kill weeds by two kinds of different mechanism, makes Weed Resistance produce speed and reduces, greatly improve the removing activity of weed killer herbicide.
2, herbicidal spectrum is wide, and the lasting period is long.Acifluorfen is broad spectrum weeding agent, and it has good preventive effect to annual gramineous weed, and Flumetsulam mainly prevents and kill off grassy weed, the weed killer herbicide of sedge weed and part broad leaved weed.After both mixing, that can improve the preventive effect of grassy weed and broad leaved weed and sedge weed, particularly annual gramineous weed and broad leaved weed and sedge weed has preventive effect, thus extends the lasting period of medicament.
3, safety is high.Medicament of the present invention is under the prerequisite that improve drug effect, and it have also been obtained raising to the safety of paddy field and succession crop.
