Abstract

The invention discloses corn field herbicide. The corn field herbicide includes effective components of tembotrione, thiencarbazone-methyl and aminopyralid (or ester compound of the aminopyralid). The corn field herbicide is prepared from, by weight, 1%-30% of the tembotrione, 1%-30% of the thiencarbazone-methyl, 1%-40% of the aminopyralid (or the ester compound of the aminopyralid) and the balance herbicide auxiliaries. The corn field herbicide has the advantages that after the tembotrione, the thiencarbazone-methyl and the aminopyralid (or the ester compound of the aminopyralid) are compounded, the weeding effect is improved, and the weeding spectrum is widened; poison and residues are low, the drug use amount, drug use frequency and the using cost are lowered obviously, the effect of the composition is obviously higher than the effects of all single components, and the corn field herbicide is good novel composition pesticide for preventing and killing annual weeds in a corn field.

Description

Corn field herbicide
Technical field
The present invention relates to a kind of corn field herbicide, be, chlorine Fampridine acid (or its ester type compound) grand with ring sulphur ketone, thiophene ketone sulphur for active ingredient, for preventing 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.
Chlorine Fampridine acid (aminopyralid), is picolinic acid class new herbicides, is mainly used in preventing and kill off annual and perennial broad leaved weed, is widely used in mountain region, grassland, the preventing and kill off of planting site and uncultivated area weeds.The different monooctyl ester of fluroxypyr (Fluroxypyr-meptyl) for pyridine fluoroacetic acid class weed killer herbicide be hormone herbicide, can be conducted by the blade of plant and root absorption, make plant deformity, distortion is dead, mainly prevents and kill off annual broadleaf weed, invalid to grassy weed.The different monooctyl ester of fluroxypyr prevents and kill off broad leaved weed as broad leaved weeds such as clearvers, chickweed, field bindweed, kitchen garden, water peanut, acalypha copperleafs with being applicable to gramineous crop field and fruit-bearing forest tea.
The present inventor is grand to ring sulphur ketone, thiophene ketone sulphur, the acid of chlorine Fampridine or the different monooctyl ester mixture of fluroxypyr conduct in-depth research, find ring sulphur ketone, thiophene ketone sulphur is grand, chlorine Fampridine sour or the different monooctyl ester mixture of fluroxypyr has Synergistic to respond, especially to Conyza canadensis (Conyzacanadensis), feather cockscomb, (Celosiaargentea), pivot stores (Polygonumaviculare) has obvious Synergistic to respond, and expands herbicide spectrum.Ring sulphur ketone, thiophene ketone sulphur are grand, chlorine Fampridine acid (or its ester type compound) 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 weed killer herbicide 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 weed killer herbicide.
Technical scheme: a kind of corn field herbicide, active ingredient is that ring sulphur ketone, thiophene ketone sulphur are grand, chlorine Fampridine acid (or its ester type compound); Ring sulphur ketone percentage by weight is in the composition 1% ~ 30%, the grand percentage by weight in the composition of thiophene ketone sulphur is 1% ~ 30%, chlorine Fampridine acid (or its ester type compound) percentage by weight is in the composition 1% ~ 40%, and all the other are insecticides adjuvant.
Described weed killer herbicide 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 oil-suspending agent, suspending agent, wetting powder or water dispersible granules.
The auxiliary agent used in weed killer herbicide 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 weed killer herbicide provided by the invention all belongs to existing known technology, does not repeat them here.
Weed killer herbicide 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.
Weed killer herbicide provided by the invention, should use when applying before the corn field annual weed 5 leaf phase.
Weed killer herbicide provided by the invention has following beneficial effect:
1, weed killer herbicide provided by the invention, in certain ratio range, show obvious synergistic effect, control efficiency is significantly improved than single dose, reduce the using dosage of agricultural chemicals, decrease times for spraying, reduce drug cost, decrease the adverse effect of agricultural chemicals to ecotope.
2, weed killer herbicide provided by the invention, the combination of two kinds of effective ingredients, expands herbicidal spectrum, and a drug can solve various weed problem, compensate for defect when single dose uses and limitation.
3, weed killer herbicide provided by the invention, effective ingredient mechanism of action is different, can overcome the shortcoming that long-term single use easily produces resistance, extends the service life of medicament, to the comprehensive regulation important in inhibiting of Weed Resistance.
4, weed killer herbicide provided by the invention, drug effect plays rapidly, and the lasting period is long, and use cost is low, easy to use, time saving and energy saving, and it applies huge economic benefit and social benefit.
