Abstract
The invention relates to a weeding composition containing thiencarbazone-methyl, pinoxaden and clodinafop-propargyl. Effective components include thiencarbazone-methyl, pinoxaden and clodinafop-propargyl. The weeding composition disclosed by the invention has a synergistic interaction effect, is obviously better in removal effect on annual weeds in a wheat paddock than a single medicament which is used independently, and has the advantages of widening the weeding spectrum, also reducing the dosage, delaying the generation of drug resistance of the weeds and reducing the environmental pollution.
Description
Technical field
The invention belongs to technical field of pesticide, be specifically related to a kind of, azoles quinoline grand with thiophene ketone sulphur grass ester, Synergistic response Herbicidal combinations that clodinafop-propargyl is active ingredient, be applicable to control wheat paddock annual weed.
Background technology
Thiophene ketone sulphur grand (thiencarbazone-methyl) is sulfonyl-amino-carbnyl triazolinone class weed killer herbicide, be inhibitor of acetolactate synthetase, thiophene ketone sulphur is grand is effectively can prevent and kill off wheat paddock grassy weed if lady's-grass, eleusine indica, barnyard grass, amur foxtail, Alopecurus and part broad leaved weed are as chickweed, clearvers etc.
Azoles quinoline grass ester (pinoxaden), azoles quinoline grass ester belongs to neophyl pyrazolines weed killer herbicide, the mechanism of action is acetyl-CoA carboxylase (ACC) inhibitor, cause fatty acid biosynthesis block, cell division is made to stop cell membrane destructurized containing fat, cause weeds dead, to wheatland wild oat, barnyard grass, green foxtail, there is good preventive effect.
Clodinafop-propargyl (clodinafop-propargyl), belong to fragrant phenoxy phenoxy propionic acid weed killer herbicide, the biosynthesis of class ester can be effectively suppressed to be the auxiliary quick A hydroxylase inhibitors of acetyl, this product is degraded to free acid phenyl very soon in soil and pyridine moiety enters soil, can prevent and treat the grassy weeds such as wheat vole tail amur foxtail, tall oat grass, perennial ryegrass, rough stalked blue grass, green foxtail.
The present invention possesses the prospect of industrial applications, by certain technological means, can excipient for ease of the formulation of agricultural use, as suspending agent, oil-suspending agent, water dispersible granules, wetting powder etc.
