Abstract
The invention relates to a foramsulfuron-containing weeding composition. The foramsulfuron-containing weeding composition is prepared from effective ingredients A, B and C and proper amount of pesticide adjuvants, wherein the effective ingredients A, B and C are respectively foramsulfuron fluid, fluroxypyr or other ester compounds, and atrazine. The compound is prepared from 1 to 20% of the effective ingredient A, 1 to 20% of the effective ingredient B, 1 to 50% of the effective ingredient in percentage by weight in the composition, and the balance of pesticide adjuvants. According to the foramsulfuron-containing weeding composition, all components are reasonable and play synergistic effect and overcome the defects of incomplete herbicide controlling spectrum or relatively low activity for certain seeds due to single use of herbicide and relatively poor fast-acting property, and the resistance risk caused by the use of single compound or double-ingredient compound can be lowered. Compared with single dosage, the foramsulfuron-containing weeding composition has the advantages that the prevention and control effects are obviously improved, the dosage of pesticides is decreased, and the adverse influence on the ecological environment caused by the pesticides can be alleviated; the foramsulfuron-containing weeding composition has an important significance on the comprehensive treatment of the weed resistance.
Description
Technical field
The present invention relates to agricultural chemicals Herbicidal combinations and application thereof, specifically a kind of Herbicidal combinations that is active ingredient with foramsulfuron, fluroxypyr or its ester type compound and atrazine, be applicable to prevent and kill off corn field annual weed.
Background technology
Foramsulfuron, sulfonylurea systemic herbicide, can be weeds cauline leaf and root absorption, conduct in plant corpus subsequently, cause sensitive plant growth retardation, cauline leaf chlorisis, withered gradually, generally 20-25 days dead, but when temperature is lower, needed to some perennial weed the longer time, dispenser good drug efficacy before 4 leaf phases after bud, when seedling is large, dispenser drug effect declines.This medical instrument has activity of weeding before bud, but activity is comparatively low after bud, can prevent and kill off annual and perennial grassy weed, part broad leaved weed.Test shows, the weeds strong to Drug Sensitivity have And-gather grass, green foxtail, wild oat, Amaranthus retroflexus; The medium weeds of susceptibility have Ben Shi knotweed, rule grass, kitchen garden, Monochoria vaginalis, Siberian cocklebur and piemarker, nutgrass flatsedge; The poor weeds of susceptibility mainly contain lamb's-quarters, black nightshade, Commelina communis, summer cypress and weasel hemp nettle.
Fluroxypyr is pyridine fluoroacetic acid class weed killer herbicide is hormone herbicide, can be conducted by the blade of plant and root absorption, make plant deformity, distortion is dead, mainly prevent and kill off annual broadleaf weed, invalid to grassy weed, its ester type compound mainly contains fluroxypyr, the different monooctyl ester of fluroxypyr, trichlopyr, triclopyr butoxyethyl ester etc., prevent and kill off broad leaved weed as clearvers with being applicable to gramineous crop field and fruit-bearing forest tea, chickweed, field bindweed, kitchen garden, water peanut, the broad leaved weeds such as acalypha copperleaf, trichlopyr or triclopyr butoxyethyl ester can prevent and kill off shrub lespedeza, aspen, elm, wormwood artemisia, radix bupleuri, balloonflower root, clematis, fern, the broad leaved weeds such as abrotanum and shrub.
Atrazine is sym-trinitrobenzene corn herbicide, absorbs and upwards conduct mainly through plant root, suppresses the photosynthesis of weeds, makes it withered.Its herbicide spectrum is wider, multiple annual gramineae and broad leaved weed can be prevented and kill off, be applicable to the dry crops such as corn, Chinese sorghum, sugarcane, fruit tree, nursery, forest land and prevent and kill off lady's-grass, barnyard grass, green foxtail, nutgrass flatsedge, amur foxtail, knotweed, lamb's-quarters, Cruciferae, pulse family weeds, especially there is good selectivity (because having detoxication mechanisms in Corn) to corn, also having certain inhibitory action to some perennial weed.
The different monooctyl ester of foramsulfuron, fluroxypyr, atrazine composite without relevant report.The present invention possesses the prospect of industrial applications, by certain technological means, can excipient be the formulation that suspending agent, oil-suspending agent, water dispersible granules, wetting powder, effervescent tablet, granulae effervescentes etc. are convenient to agriculturally use.
The present inventor conducts in-depth research foramsulfuron, the different monooctyl ester of fluroxypyr, atrazine mixture, find that foramsulfuron, the different monooctyl ester of fluroxypyr, atrazine mixture have Synergistic to respond, especially have obvious Synergistic to respond to green foxtail (Setaria viridis), piemarker (Abutilon theophrasti), the rhizome of nutgrass flatsedge (Cyperus rotundus L.).
Summary of the invention
The object of the invention is to the deficiency solving existing weed killer herbicide, a kind of Herbicidal combinations having synergistic function, expand the corn field that herbicide is composed, use cost is low, control efficiency is good is provided.
Technical scheme of the present invention is: a kind of Herbicidal combinations, be made up of effective constituents A, B, C and suitable insecticides adjuvant, wherein effective constituents A is foramsulfuron, B is fluroxypyr or its ester type compound, C is atrazine, effective constituents A, B, C percentage by weight is in the composition respectively 1% ~ 20%, 1% ~ 20%, 1% ~ 50%, and all the other are insecticides adjuvant.
Described Herbicidal combinations those skilled in the art can according to known method, select suitable pesticidal preparations auxiliary element, excipient suspending agent, dispersible oil-suspending agent, water dispersible granules, wetting powder, effervescent tablet, granulae effervescentes etc. and be applicable to the formulation that agriculturally uses.
The processing technology of the various preparation of Herbicidal combinations of the present invention is prior art, can change to some extent according to different situations.
The insecticides adjuvant used in Herbicidal combinations of the present invention comprises solvent, emulsifier, wetting agent, stabilizing agent, dispersant, disintegrant, binding agent, thickener, pH adjusting agent, defoamer, antifreezing agent, filler, carrier etc., and to be of value to active ingredient stable and play the known substance of drug effect in the formulation, be all various compositions that are conventional in pesticidal preparations or permission use, concrete composition and consumption are determined by test according to recipe requirements.
The frequency of administration of Herbicidal combinations of the present invention and amount of application change with crops, weeds, weather condition and have small variations, can by the object using suitable dosage reach effectively control.
Triple combination of the present invention (i.e. foramsulfuron fluroxypyr different monooctyl ester atrazine) can solve weed killer herbicide single or two yuan use time deficiency, expand herbicide spectrum, and composition has Synergistic response, especially to green foxtail (Setaria viridis), piemarker (Abutilontheophrasti), the rhizome of nutgrass flatsedge (Cyperus rotundus L.) has the response of obvious Synergistic, excellent fix can be provided for preventing and kill off of corn field annual weed, especially to green foxtail (Setaria viridis), piemarker (Abutilon theophrasti), the corn field of the rhizome of nutgrass flatsedge (Cyperusrotundus L.) advantage weeds, for the corn field weed comprehensive regulation, there is positive effect.
