Abstract
The invention relates to a herbicidal composition, the effective components of which are flumetsulam and pyraflufen-ethyl in a ratio of 30:1-1:30. A large number of indoor prescription screening tests and field pharmacodynamic tests show that the herbicidal composition provided by the invention has an obvious synergistic effect on cleavers and veronica didyma within a certain mixing proportion range, improves the herbicidal effect, expands the herbicidal spectrum, and is applicable to prevention and killing of annual broadleaf weeds in wheat field.
Description
Technical field
The invention belongs to agriculture weeding technical field, be specifically related to a kind of Herbicidal combinations taking Flumetsulam, pyrrole grass ether as active ingredient, be applicable to prevent and kill off wheat paddock annual broadleaf weed.
Background technology
Along with progressively eliminating of high-toxic pesticide, need efficient, low toxicity, safety, environment amenable pharmaceutical preparations, the long-term use of agricultural chemicals simultaneously produces the pesticide resistance of disease pest and weed, requirement to control medicament is also more and more higher, this just needs agricultural chemicals research staff to develop the pharmaceutical preparations of highly effective and safe, meets control requirement.Because China's agricultural chemicals initiative is at the early-stage, the pesticide species with independent intellectual property right can't be satisfied the demand, and the therefore pesticide mixed preparation of development of new is the only way of current Agrochemicals.
Flumetsulam is triazolopyrimidine sulfonamides, is typical inhibitor of acetolactate synthetase.By suppressing the synthetic protein biosynthesis block that makes of branched-chain amino acid, plant stops growing.Longevity of residure length, broad weed-killing spectrum, soil, cauline leaf are processed and all can.Be suitable for the Tanakas such as corn, soybean, wheat, barley, clover, clover prevent and treat life in 1 year and perennial broadleaf weed as meadow pine (joint bone grass), shepherd's purse, wallflower, pepper grass, broadcast ma wormwood artemisia (wheat wormwood artemisia), knotweed, Veronica (quilt wadding), Siberian cocklebur (old ground), black nightshade (bryony), Amaranthus retroflexus (three-coloured amaranth), lamb's-quarters (grey dish), piemarker (really numb), clearvers (puckery uprooting plants after their edible portions have been harvested), datura etc.Children grassy weed in age is also had to certain inhibitory action.
Pyrrole grass ether is proporphyrinogen oxidase inhibitor, and after wheat paddock selectivity seedling in seedling stage, cauline leaf is processed weed killer herbicide, is mainly used in preventing and kill off broad leaved weed, and to clearvers special efficacy.
Weed killer herbicide is rationally composite is to improve preventive effect, expand herbicide spectrum or widen service time, delaying the speed of shift of weed community, reducing the resistance risk that the single use of agricultural chemicals brings, alleviate the pollution to environment, reduce a kind of effective ways of use cost and reduction herbicide residue.The inventor conducts in-depth research the mixture of Flumetsulam, pyrrole grass ether, on the basis of a large amount of formula indoor screening tests and field medicine effect test, find that Flumetsulam, pyrrole grass ether carry out mixture, within the scope of certain mixed ratio, clearvers, Veronica are shown to synergistic function, after further study, completed the present invention.
Summary of the invention
The object of the invention is to solve the deficiency that weed killer herbicide is single while using, provide a kind of efficient, low toxicity, low cost, quick-acting good, and the lasting period is long, is conducive to the Herbicidal combinations of the weeds of wheat comprehensive regulation.
Technical scheme of the present invention: a kind of Herbicidal combinations that contains Flumetsulam and pyrrole grass ether, formed by active ingredient Flumetsulam, pyrrole grass ether and suitable insecticides adjuvant, the ratio of weight and number of Flumetsulam and pyrrole grass ether is 30:1～1:30.
Described Herbicidal combinations those skilled in the art can be according to known method, selects suitable pesticidal preparations auxiliary element, the formulation using in the applicable agriculturals such as excipient wetting powder, water dispersible granules.
The processing technology of the various preparations of Herbicidal combinations of the present invention is prior art, can change to some extent according to different situations.
The insecticides adjuvant using in Herbicidal combinations of the present invention comprises that solvent, emulsifier, wetting agent, stabilizing agent, dispersant, thickener, pH adjusting agent, defoamer, antifreezing agent, packing agent etc. are of value to the known substance of active ingredient stable and performance drug effect in preparation, be all various compositions conventional in pesticidal preparations or that permission is used, concrete composition and consumption require to determine by test according to formula.
Herbicidal combinations provided by the invention, is applicable to prevent and kill off wheat paddock annual broadleaf weed.
Herbicidal combinations provided by the invention has following beneficial effect:
1, Herbicidal combinations provided by the invention, expand the herbicide spectrum of Flumetsulam and pyrrole grass ether single dose, within the scope of 30:1～1:30, clearvers, Veronica are shown to obvious synergistic function, the control efficiency of composition has had raising than single dose, reduce the using dosage of agricultural chemicals, reduced drug cost and the agricultural chemicals risk to ecotope adverse effect.
2, provided by the invention is Herbicidal combinations, can reduce the resistance risk that the single Flumetsulam of long-term use or pyrrole grass ether produce, and extends the service life of medicament, to the comprehensive regulation important in inhibiting of Weed Resistance.
