Abstract

The invention discloses a corn field weeding composition. The corn field weeding composition is composed of 1-40wt% of an effective component A, 1-10wt% of an effective component B, 1-50wt% of an effective component C, and the balance of a suitable pesticide assistant, the effective component A is tembotrione, the effective component B is one selected from thiencarbazone-methyl and nicosulfuron, and the effective component C is atrazine. The composition has the advantages of weeding improvement effect, weed control spectrum enlargement, low toxicity, low residual, and substantial reduction of the drug dosage, the use frequency and the use cost, has obviously better effects than single doses, and is a novel composition medicine having a good control effect on annual weeds in the corn field.

Description

Cornfield weeding composition
Technical field
The invention belongs to technical field of pesticide, be specifically related to a kind of Synergistic Herbicidal combinations that grand or nicosulfuron, atrazine are active ingredient with ring sulphur ketone, thiophene ketone sulphur, be applicable to prevent and kill off corn field annual weed.
Background technology
Ring sulphur ketone (Tembotrione), it is a kind of three ketones selective herbicide, effectively can prevent and treat main broadleaved herb and some grassy weeds, as piemarker, three-coloured amaranth, lamb's-quarters, knotweed, barnyard grass, lady's-grass etc. have good control efficiency, can be used for cauline leaf process after Seal treatment and bud before bud.
Thiophene ketone sulphur grand (Thiencarbazone-methyl) is sulfonyl-amino-carbnyl triazolinone class weed killer herbicide, is inhibitor of acetolactate synthetase.Thiophene ketone sulphur is grand is effectively can prevent and kill off corn field grassy weed as lady's-grass, eleusine indica, barnyard grass, green foxtail etc. and most of broad leaved weed, registration is used for corn (land for growing field crops, sweet corn, popcorn), wheat and be used for preventing and kill off annual weed on the lawn of residence area and ornamental plants, all can use in early days before bud and after bud, after bud, using dosage is far below using dosage before bud.Nicosulfuron (Nicosulfuron) is sulfonylurea systemic herbicide, it is inhibitor of acetolactate synthetase, can be weeds cauline leaf and root absorption, conduct in plant corpus subsequently, cause sensitive plant growth retardation, cauline leaf chlorisis, withered gradually, generally death in 20-25 days, 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.
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.
To ring sulphur ketone, thiophene ketone sulphur, grand or nicosulfuron, atrazine mixture conduct in-depth research the present inventor, find the grand or nicosulfuron of ring sulphur ketone, thiophene ketone sulphur, atrazine mixture has Synergistic to respond, especially sting amaranth (Amaranthusspinosus), field thistle (Cirsiumsetosum), acalypha copperleaf (Acalyphaaustralis) have obvious Synergistic to respond, expand herbicide spectrum.Grand or the nicosulfuron of ring sulphur ketone, thiophene ketone sulphur, atrazine composite without relevant report.
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 are good and the lasting period is long, are conducive to the Herbicidal combinations of the farmland weed comprehensive regulation.
Another object of the present invention is used for preventing and kill off corn field annual weed etc. by this Herbicidal combinations.
Technical scheme: for achieving the above object, the invention provides a kind of cornfield weeding composition, be made up of effective constituents A, active ingredient B, active ingredient C and suitable insecticides adjuvant, effective constituents A is ring sulphur ketone, active ingredient B is selected from one in the grand or nicosulfuron of thiophene ketone sulphur, active ingredient C is atrazine; Wherein, effective constituents A percentage by weight is in the composition that 1% ~ 40%, active ingredient B percentage by weight is in the composition 1% ~ 10%, active ingredient C percentage by weight is in the composition 1% ~ 50%, and all the other are insecticides adjuvant.
Described Herbicidal combinations can add suitable insecticides adjuvant, according to well known to a person skilled in the art method, is processed into the application forms of the applicable agricultural uses such as suspending agent, oil-suspending agent, water dispersible granules, wetting powder.
The auxiliary agent used 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 are determined by simple test according to recipe requirements.
The production technology of the various application forms of Herbicidal combinations provided by the invention all belongs to existing known technology, no longer superfluous at this.
Herbicidal combinations provided by the invention, usually adopts and is watered the use of cauline leaf spray method, also can adopt other operation techniques agriculturally applied as required.
Herbicidal combinations provided by the invention, should use when applying before the corn field annual weed 5 leaf phase.
Compared with prior art, the invention has the advantages that: triple combination (i.e. ring sulphur ketone thiophene ketone sulphur grand or nicosulfuron atrazine) can solve single or two yuan of deficiencies when using of weed killer herbicide, expand herbicide spectrum, and composition has Synergistic response, especially to thorn amaranth (Amaranthusspinosus), field thistle (Cirsiumsetosum), acalypha copperleaf (Acalyphaaustralis) has the response of obvious Synergistic, excellent fix can be provided for preventing and kill off of corn field annual weed, especially to sting amaranth (Amaranthusspinosus), field thistle (Cirsiumsetosum), the corn field of acalypha copperleaf (Acalyphaaustralis) advantage weeds, for the corn field weed comprehensive regulation, there is positive effect.
