Abstract
The invention discloses a pesticide composition containing tembotrions, nicosulfuron and a pyridyloxyacetic acid herbicide. The effective components are the tembotrions, the nicosulfuron and the pyridyloxyacetic acid (or the ester compound of the pyridyloxyacetic acid). The weight percentage of the tembotrions in the herbicide is 1%-30%, the weight percentage of the nicosulfuron in the herbicide is 1%-30%, the weight percentage of the pyridyloxyacetic acid (or the ester compound of the pyridyloxyacetic acid) in the herbicide is 1%-40%, and the balance is pesticide adjuvants. The pesticide composition has the advantages that the weeding effect is improved after the tembotrions, the nicosulfuron and the pyridyloxyacetic acid (or the ester compound of the pyridyloxyacetic acid) are compounded, a weeding spectrum is widened, the pesticide composition is low in toxicity and low in residue content, the dosage, the application frequency and the using cost are remarkably reduced, the effect of the composition is obviously higher than those of mono-agents, and the pesticide composition is a novel better composition pesticide for preventing and removing annual weed in corn fields.
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 ring sulphur ketone, nicosulfuron, the acid of chlorine Fampridine or the different monooctyl ester of fluroxypyr, be mainly applicable to prevent and kill off corn field especially with the corn field annual weed that Alternanthera philoxeroides (Alternantheraphiloxeroides), dayflower (Commelinacommunis), acalypha copperleaf (Acalyphaaustralis) are advantage weeds.
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.
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.
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 conducts in-depth research ring sulphur ketone, nicosulfuron, the acid of chlorine Fampridine or the different monooctyl ester mixture of fluroxypyr, find that ring sulphur ketone, nicosulfuron, the acid of chlorine Fampridine or the different monooctyl ester mixture of fluroxypyr have Synergistic to respond, especially there is obvious Synergistic to respond to Alternanthera philoxeroides (Alternantheraphiloxeroides), dayflower (Commelinacommunis), acalypha copperleaf (Acalyphaaustralis), expand herbicide spectrum.The acid of ring sulphur ketone, nicosulfuron, chlorine Fampridine or the different monooctyl ester of fluroxypyr 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 ring sulphur ketone, nicosulfuron, chlorine Fampridine acid (or its ester type compound); Ring sulphur ketone percentage by weight is in the composition 1% ~ 30%, nicosulfuron percentage by weight is in the composition 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 inventing the various application forms of weed killer herbicide provided 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.
