Abstract
The invention relates to an herbicide composition containing metamifop, cyhalofop-butyl and halosulfuron-methyl. The herbicide composition contains active ingredients of the metamifop, the cyhalofop-butyl and the halosulfuron-methyl, wherein the metamifop accounts for 1-20wt% of the composition, the cyhalofop-butyl accounts for 1-30wt% of the composition and the halosulfuron-methyl accounts for 1-20wt% of the composition. The herbicide composition disclosed by the invention has a synergetic effect; in the control and removal of annual weeds in a paddy field, the effect of the herbicide composition is significantly better than that of various single agent in independent use; the herbicide composition can be used for widening a weeding spectrum, and the herbicide composition can be also used for reducing the use quantity of pesticides, reducing weed resistance risks, relieving environment pollution and delaying the generation of weed resistance.
Description
Technical field
The invention belongs to technical field of pesticide, be specifically related to Yi Zhong Yi metamifop, Synergistic response Herbicidal combinations that cyhalofop-butyl, halosulfuronmethyl are active ingredient, be mainly applicable to prevent and kill off paddy field annual weed.
Background technology
Metamifop (metamifop) can resist acetyl-CoA carboxylase, fatty acid is synthesized and stops, and the growth division of cell can not normally be carried out, and membranous system etc., containing fat structural deterioration, finally cause Plant death.Metamifop is usually used in annual gramineous weed such as control moleplant seed, barnyard grass, lady's-grass etc., to sedge weed and broad leaved weed invalid.
Cyhalofop-butyl (cyhalofop-buty) is only kind paddy rice to tight security in fragrant phenoxy phenoxy propionic acid weed killer herbicide, the same with such other kinds, is also Uptake and translocation weed killer herbicide.By blade and the leaf sheath absorption of plant corpus, phloem conducts, accumulate the meristem zone in plant corpus, resist acetyl-CoA carboxylase (ACCase), fatty acid is synthesized stop, the growth division of cell can not normally be carried out, and membranous system etc., containing fat structural deterioration, finally cause Plant death.Cyhalofop-butyl is efficient to moleplant seed, have certain preventive effect to low age barnyard grass, also can prevent and kill off, lady's-grass, Paspalum distichum, amur foxtail etc.To sedge weed and broad leaved weed invalid.
Halosulfuronmethyl (halosulfuron-methyl), belong to sulfonylurea herbicide, the synthesis of weeds branched-chain amino acid can be suppressed, thus suppress the biosynthesis of valine, leucine, isoleucine, stop cell division, sensitive crop is stopped growing.Be usually used in broad leaved weed and the sedge weeds such as water prevention rice field Monochoria vaginalis, triquetrousc murdannia herb, special-shaped nutgrass flatsedge, have certain inhibitory action to grassy weed.
By the screening of different pesticide species compounded formula, filter out rational formula, effectively can improve the actual control efficiency to disease pest and weed, expanding prevention is composed, reduce dosage, reduce costs, alleviate the pollution to environment, delaying the drug-fast generation of disease pest and weed, is the important means of the agriculturally disease pest and weed comprehensive regulation.
The present inventor Dui metamifop, cyhalofop-butyl, halosulfuronmethyl mixture conduct in-depth research Fa Xian metamifop, cyhalofop-butyl, halosulfuronmethyl mixture have Synergistic to respond, and especially have obvious Synergistic to respond to moleplant seed, barnyard grass, lady's-grass, Paspalum distichum, Monochoria vaginalis, alternanthera philoxeroides, triquetrousc murdannia herb etc.
Metamifop, cyhalofop-butyl, halosulfuronmethyl composite without relevant report.
Summary of the invention
The object of the present invention is to provide a kind of Herbicidal combinations that there is synergistic function, expand the paddy field that herbicide is composed, use cost is low, control efficiency is good.
The technical scheme realizing the object of the invention is: a kind of Herbicidal combinations, active ingredient Wei metamifop and cyhalofop-butyl and halosulfuronmethyl metamifop percentage by weight are in the composition 1% ~ 20%, cyhalofop-butyl percentage by weight is in the composition 1% ~ 30%, halosulfuronmethyl percentage by weight is in the composition 1% ~ 20%, and all the other are agriculturally acceptable pesticidal preparations auxiliary element.
Described Herbicidal combinations according to well known to a person skilled in the art method, can be selected suitable pesticidal preparations auxiliary element, can be processed into the application forms that the applicable agricultural productions such as suspending agent, oil-suspending agent, water dispersible granules, wetting powder use.
The auxiliary element that the present invention uses comprises wetting agent, stabilizing agent, dispersant, disintegrant, thickener, pH adjusting agent, defoamer, antifreezing agent, filler etc., be all auxiliary agent conventional in Pesticide formulation, concrete composition and consumption are determined by test according to recipe requirements.
Herbicidal combinations provided by the invention, is applicable to prevent and kill off paddy field annual weed.
The frequency of administration of Herbicidal combinations provided by the invention and amount of application change with crops, weeds, weather condition and have small variations, can by the object using suitable dosage reach effectively control.
Product described in the invention can the form of finished product preparation provide, and namely in composition, each material mixes, and the composition of composition also can the form of single dose provide, and directly mixes in tank or bucket, be then diluted to required concentration before using.
Compared with prior art, the invention has the advantages that:
Triple combination (of the present invention and metamifop cyhalofop-butyl halosulfuronmethyl) expand herbicide spectrum, composition has Synergistic response to target, especially to moleplant seed, special-shaped nutgrass flatsedge, there is the response of obvious Synergistic, excellent fix can be provided for preventing and kill off of paddy field annual weed, especially with the paddy field of moleplant seed, special-shaped nutgrass flatsedge, for the paddy field weed comprehensive regulation, there is positive effect.
Embodiment
In order to make object of the present invention, technical scheme and advantage more short and sweet, the following specific embodiment of the present invention is described, but the present invention is only limitted to absolutely not these examples.The following stated is only the good embodiment of the present invention, only for describing the present invention, can not be interpreted as the restriction to scope of the present invention.It should be pointed out that all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
