Abstract
A weeding composition is disclosed. Effective components of the weeding composition are butafenacil and quizalofop-p-ethyl. The weight ratio of the butafenacil to the quizalofop-p-ethyl is 20:1-1:20. The weeding composition is suitable for weed control in orchards, bare places, vine crop fields, and cotton fields, and enhances weeding effects than use of a single agent. The weeding composition expands the weeding range, is safe to crops, reduces the pesticide using amount, relieves pollution of pesticides to the environment, and delays generation of drug resistance of weeds.
Description
Technical field
The invention belongs to technical field of pesticide, be specifically related to a kind of Synergistic Herbicidal combinations taking butafenacil, Quizalotop-ethyl as active ingredient.
Background technology
Butafenacil (butafenacil), non-selective uracil weeding agent, be mainly used in orchard, uncultivated area, Cotton Fields, vine crop field and prevent and kill off important broad leaved weed, grassy weed and sedge weed, also can be used for weeding before the crop seedlings such as wheat.
Quizalotop-ethyl absorbs by weeds cauline leaf, and Bidirectional Conduction up and down in plant corpus, is accumulated in top and mitogenetic between two parties, suppresses cell fatty acid synthetic, makes weeds necrosis.Lasting period is long, and the annual and perennial grassy weed to the initial stage of tillering, ear after emerging is all had to good preventive effect.Under normal service condition to various broad leaf crop high safeties.Be mainly used in preventing and kill off annual and perennial grassy weed.
By test, we have found that butafenacil and Quizalotop-ethyl within the scope of certain mixed ratio to Veronica (eronica didyma) Siberian cocklebur (Xanthium sibiricum), horehound (Lagopsis supina), hairy knotweed herb or root (Polygonum criopolitanum), buttercup (Ranunculus japonicus), common vetch (Vicia gigantea), Sudan grass (Sorghum sudanense), Bermuda grass (Cynodon dactylon), eleusine indica (Eleusine indica), Mao Yingcao (Alloteropsis semialata), bent grass (Agrostis matsumurae), little Hua bent grass (Agrostis micrantha), Huang Mao (Heteropogon contortus), Li Shi standing grain (Leersia hexandra), the weeds such as not plump shell grass (Leersia sayanuka) have synergistic function, after further study, complete the present invention.
Do not find at present the composite relevant report of butafenacil and Quizalotop-ethyl.
Summary of the invention
The object of the invention is to solve in prior art to farmland weed develop immunity to drugs problem and actual control efficiency poor, provide a kind of efficient, low toxicity, quick-acting is good and the lasting period is long, is conducive to the Herbicidal combinations of the farmland weed comprehensive regulation.
Another object of the present invention be by this Herbicidal combinations for preventing and kill off farmland weed, be particularly useful for preventing and kill off orchard, uncultivated area, vine crop field, Cotton Fields weeds.
Technical scheme of the present invention is: a kind of Herbicidal combinations that contains butafenacil and Quizalotop-ethyl, and active ingredient is butafenacil and Quizalotop-ethyl, the ratio of weight and number of butafenacil and Quizalotop-ethyl is 20:1～1:20.
Herbicidal combinations of the present invention can adopt by known method, selects suitable auxiliary agent to be prepared into and is applicable to upper any one formulation using of agricultural, and reasonable formulation has suspending agent, oil-suspending agent, water dispersible granules, wetting powder.The processing technology of the various preparations of the present composition is prior art, can change to some extent according to different situations.
The auxiliary agent 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.
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.
The frequency of administration of Herbicidal combinations of the present invention and amount of application have small variations with crops, weeds, weather condition variation, can be by using suitable dosage to reach the object of effective control.
The present invention has expanded herbicide spectrum, and composition has Synergistic response to target, can provide good solution for uncultivated area, orchard, Cotton Fields, preventing and kill off of vine crop field weed, and the weeds comprehensive regulation is had to positive effect.
