Abstract
The invention relates to a weeding composition containing mesotrione, halosulfuron-methyl and atrazine. The weeding composition comprises effective components mesotrione, halosulfuron-methyl and atrazine at a weight ratio of (1-30):(1-30):(1-50). The weeding composition has synergistic interaction for weeds in corn fields and is applicable to preventing and removing annual weeds in corn fields, the herbicide controlling spectrum can be widened, and the weeding resistance risk can be reduced.
Description
Technical field
The invention belongs to technical field of pesticide, be specifically related to a kind of Synergistic response Herbicidal combinations being active ingredient with mesotrione, halosulfuronmethyl, atrazine, especially to barnyard grass (Echinochloacrusgalli), lady's-grass (Digitaria sanguinalis), the response of the rhizome of nutgrass flatsedge (Cyperus rotundusL.) Synergistic obviously.
Background technology
Mesotrione is also known as mesotrione (Mesotrione), for three ketones type herbicides is systemics, absorbed by root system of plant and blade, and conduct in vivo, suppress hydroxyphenyl pyravate dual oxide enzyme, cause the accumulation of tyrosine, the biosynthesis of plastoquinone and vitamin e stops, and then cause chlorophyllous content to decline, make plant meristematic tissue chlorosis produce albefaction dead, annual broadleaf weed and part grassy weed can be prevented and kill off, can cauline leaf process after native list processing and seedling before seedling, in soil, residual life, is shorter, to succession crop safety.
Halosulfuronmethyl (Halosulfuron-methrl), for sulfonylurea wide spectrum selectivity inner-adsorption conduction-type herbicide, absorbed mainly through root system, also absorb by cauline leaf, shift rapidly in weeds plant body, Developing restraint, weeds are dead gradually, annual broadleaf weed and sedge weed can be prevented and kill off, be applicable to the crop such as corn, paddy rice.
Atrazine (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 comparatively wide, can prevent and kill off multiple annual gramineae and broad leaved weed.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.
Mesotrione, halosulfuronmethyl, atrazine composite without relevant report.
The present inventor conducts in-depth research mesotrione, halosulfuronmethyl, atrazine mixture, find that mesotrione, halosulfuronmethyl, atrazine mixture have Synergistic to respond, especially there is obvious Synergistic to respond to barnyard grass (Echinochloa crusgalli) lady's-grass (Digitaria sanguinalis), the rhizome of nutgrass flatsedge (Cyperus rotundus L.), expand herbicide spectrum.
Summary of the invention
The object of the present invention is to provide a kind of there is synergistic function, expand herbicide spectrum, low, the control efficiency of use cost the is good Herbicidal combinations containing mesotrione and halosulfuronmethyl and atrazine and preventing and kill off the application in corn field annual weed.
The technical scheme realizing the object of the invention is: Herbicidal combinations of the present invention is with mesotrione and halosulfuronmethyl and atrazine for active ingredient, and the weight ratio of mesotrione and halosulfuronmethyl and atrazine is 1 ~ 30:1 ~ 30:1 ~ 50; Mesotrione and halosulfuronmethyl and atrazine weight summation percentage by weight are in the composition 5% ~ 80%, and all the other are allow in agricultural chemicals to use and acceptable auxiliary element.
Described auxiliary element comprises solvent, emulsifier, wetting agent, dispersant, antifreezing agent, thickener, disintegrant, binding agent, defoamer, stabilizing agent, bleeding agent, synergist, solid acid, carbonate, flowing regulator, liquid-carrier and solid carrier etc., it is all composition that is conventional in pesticidal preparations or permission use, be not particularly limited, concrete composition and consumption are determined by simple test according to recipe requirements.
Herbicidal combinations of the present invention can be prepared into the multiple application forms being applicable to agriculturally using, and reasonable formulation has oil-suspending agent, suspending agent, wetting powder, water dispersible granules.
The production technology of the various application forms of described Herbicidal combinations all belongs to existing known technology, does not repeat them here.
The frequency of administration of the present composition and amount of application change with crops, weeds, weather condition and have small variations, can by the object using suitable dosage reach effectively control.
Beneficial effect: triple combination of the present invention (i.e. mesotrione halosulfuronmethyl atrazine) can solve weed killer herbicide single or two yuan use time deficiency, expand herbicide spectrum, and composition has Synergistic response, especially to barnyard grass (Echinochloa crusgalli), lady's-grass (Digitariasanguinalis), 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 barnyard grass (Echinochloa crusgalli) lady's-grass (Digitaria sanguinalis), the corn field of the rhizome of nutgrass flatsedge (Cyperus rotundus L.) advantage weeds, for the corn field weed comprehensive regulation, there is positive effect.
