Abstract
The invention relates to a weeding composition containing pyraflufen-ethyl and bentazone. The effective components comprise pyraflufen-ethyl and bentazone in a weight ratio of 30:1-1:30. The weeding composition is suitable for preventing and eliminating annual broadleaf weeds and sedge weeds in wheat fields, has obviously better weeding effects than a single agent, has wider weed control spectrum, is safe for wheat, lowers the pesticide consumption, reduces the environmental pollution caused by pesticide, and postpones the generation of drug resistance of weeds.
Description
Technical field
The invention belongs to agriculture weeding technical field, be specifically related to a kind ofly take pyrrole grass ether and bentazone as the Wheat field weeding composition of active ingredient, be applicable to prevent and kill off wheat paddock annual broadleaf weed and sedge 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.
Bentazone is optionally contact killing type herbicide after seedling of a kind of tool, for the processing of weeds cauline leaf in seedling stage.Be mainly used in the crops such as paddy rice, soybean, peanut, wheat, prevent and kill off broad leaved weed and sedge weed, invalid to grassy weed.
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 bentazone, pyrrole grass ether, on the basis of a large amount of formula indoor screening tests and field medicine effect test, find that bentazone, pyrrole grass ether carry out mixture, within the scope of certain mixed ratio, clearvers, chickweed 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 is: a kind of Herbicidal combinations, by active ingredient bentazone, pyrrole grass ether and suitable insecticides adjuvant, formed, and the ratio of weight and number of bentazone 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 of using in the applicable agriculturals such as excipient wetting powder, water dispersible granules.
The processing technology of the various preparations of the present composition is prior art, according to different situations, can change to some extent.
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 of the present invention is applicable to prevent and kill off farmland weed, especially wheat paddock annual broadleaf weed and sedge weed.
Herbicidal combinations provided by the invention, adopts the method for spraying to use conventionally, also can adopt as required other operation techniques of the upper application of agricultural.Such as conventional agricultural chemicals using method: spray-on process, powder injection process, pesticide-clay mixture method etc.
Product described in the invention can finished product preparation form provide, in composition, each material mixes, the form that the composition of composition also can single dose provides, and before use, directly in tank or bucket, mixes, and is then diluted to needed concentration.The frequency of administration of the present composition and amount of application change with weather conditions and weeds situation, can be by using suitable dosage to reach the object of preventing and kill off.
Herbicidal combinations provided by the invention has following beneficial effect:
1, Herbicidal combinations provided by the invention, expanded herbicide spectrum, within the scope of 30:1～1:30, the weeds such as wheat paddock clearvers, chickweed 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 bentazone 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.
