Abstract
The invention discloses a weed control composition containing halosulfuron-methyl. The weed control composition comprises the following ingredients by weight percent: 0.1-50% of topramezone, 1-40% of halosulfuron-methyl,1-60% of cyanazine and the balance of pesticide adjuvants, wherein the topramezone, the halosulfuron-methyl and the cyanazine are active ingredients. The weed control composition is used for controlling annual weeds in the corn fields, has obviously effects better than the corresponding single agent, expands the weed control spectrum, also reduces the dosage, delays the drug resistance of weeds and reduces environmental pollution.
Description
Technical field
The invention belongs to technical field of pesticide, be specifically related to a kind of Herbicidal combinations taking benzene pyrazoles humulone, halosulfuronmethyl, cyanazine as active ingredient, for preventing and kill off corn field annual weed.
Background technology
Benzene pyrazoles humulone (topramezone), for cauline leaf inorganic agent after pyrazolone seedling, can be absorbed by root, young stem and leaf, by suppressing the 4-medical midbodies of para (ortho)-hydroxybenzoic acetone acid esters dual oxide enzyme (4HPPD) in plastoquinone biosynthesis, synthesizing of remote-effects carotenoid, synthetic and the function of disturbing chloroplast, finally causes serious albefaction (due to chlorophyllous degraded), corn is had to the selectivity of height.
Halosulfuronmethyl (halosulfuron-methrl), for sulfonylurea wide spectrum selectivity inner-adsorption conduction-type herbicide, mainly be absorbed by root system, also can absorb by cauline leaf, in weeds plant body, shift rapidly, suppress growth, weeds are dead gradually, can prevent and kill off annual broadleaf weed and sedge weed, be applicable to the crop such as corn, paddy rice.
Cyanazine (cyanazine), is sym-trinitrobenzene corn herbicide, mainly absorbs by plant root and upwards conduction, suppresses the photosynthesis of weeds, makes it withered.Its herbicide spectrum is wider, can prevent and kill off multiple annual gramineae and broad leaved weed.Be applicable to the dry crops such as corn, pea, broad bean, potato, sugarcane, cotton and prevent and kill off lady's-grass, barnyard grass, nutgrass flatsedge, amur foxtail, knotweed, lamb's-quarters, Cruciferae, pulse family weeds, especially corn is had to good selectivity (because there being removing toxic substances mechanism in Corn), some perennial weed is also had to certain inhibitory action.
Benzene pyrazoles humulone, halosulfuronmethyl, cyanazine composite without relevant report.
The present invention possesses the prospect of industrial applications, by certain technological means, can excipient be suspending agent, oil-suspending agent, water dispersible granules, wetting powder, effervescent tablet, granulae effervescentes etc.
The inventor conducts in-depth research benzene pyrazoles humulone, halosulfuronmethyl, cyanazine mixture, find that benzene pyrazoles humulone, halosulfuronmethyl, cyanazine mixture have Synergistic response, especially barnyard grass (Echinochloa crusgalli (L.) Beauv), the rhizome of nutgrass flatsedge (Cyperus rotundus L.) are had to obvious Synergistic response, expand herbicide spectrum.
Summary of the invention
When the object of the invention is to solve prior art Pesticides single dose and using separately, to the problem that weeds easily develop immunity to drugs and actual control efficiency is poor, provide a kind of efficient, wide spectrum, economy, safety, be conducive to the Herbicidal combinations of the weeds comprehensive regulation.
Technical scheme of the present invention is: a kind of Herbicidal combinations that contains benzene pyrazoles humulone, and active ingredient is benzene pyrazoles humulone, halosulfuronmethyl and cyanazine; The percentage by weight of benzene pyrazoles humulone in composition is 0.1%～50%, and the percentage by weight of halosulfuronmethyl in composition is 1%～40%, and the percentage by weight of cyanazine in composition is 1%～60%, and all the other are insecticides adjuvant.
Herbicidal combinations of the present invention can, according to well known to a person skilled in the art method, can be processed into the application forms using in the applicable agricultural productions such as suspending agent, oil-suspending agent, water dispersible granules, wetting powder, effervescent tablet, granulae effervescentes.
The insecticides adjuvant using in Herbicidal combinations of the present invention comprises solvent, emulsifier, wetting agent, stabilizing agent, dispersant, thickener, pH adjusting agent, defoamer, antifreezing agent, deionized water, filler etc., be all various auxiliary agents conventional in Pesticide formulation, concrete composition and consumption required simple test to determine according to formula.
The production technology of the various application forms of Herbicidal combinations of the present invention all belongs to existing known technology, does not repeat them here.
The frequency of administration of the present composition 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 can solve weed killer herbicide single or two yuan use time deficiency, expand herbicide spectrum, and composition has Synergistic response, especially barnyard grass (Echinochloa crusgalli (L.) Beauv) and the rhizome of nutgrass flatsedge (Cyperus rotundus L.) are had to obvious Synergistic response, can provide good solution for preventing and kill off of corn field annual weed, especially to barnyard grass (Echinochloa crusgalli (L.) Beauv), the corn field of the rhizome of nutgrass flatsedge (Cyperus rotundus L.) advantage weeds, for corn field weed, the comprehensive regulation has positive effect.
