Abstract
The invention relates to a cornfield weeding composite. The cornfield weeding composite comprises the effective components including thiencarbazone-methyl, aminopyralid (or a salt compound) and mesotrione. The cornfield weeding composite has a synergistic interaction function, annual weed prevention and removal effect in the cornfield achieved by using the weeding composite is obviously superior to that achieved by separately using single dosage; moreover, the herbicide controlling spectrum is enlarged; meanwhile, the pesticide using amount is reduced, the production of weed pesticide-resistant property is delayed, and the pollution to the environment is reduced.
Description
Technical field
The invention belongs to technical field of pesticide, be specifically related to a kind of, chlorine Fampridine acid (or its esters compound) grand with thiophene ketone sulphur, Synergistic response Herbicidal combinations that mesotrione is active ingredient, be applicable to prevent and kill off corn field annual weed.
Background technology
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), for picolinic acid class new herbicides, be mainly used in preventing and kill off annual and perennial broad leaved weed, be widely used in mountain region, grassland, the preventing and kill off of planting site and uncultivated area weeds, the acid of chlorine Fampridine is reacted to potassium hydroxide, sodium hydroxide, ammoniacal liquor etc. and can also be obtained corresponding salt.
Mesotrione has another name called mesotrione (mesotrione), be one can suppress medical midbodies of para (ortho)-hydroxybenzoic acetone acid esters dual oxide enzyme (HPPD) bud before and wide spectrum selective herbicide after seedling, 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.
Thiophene ketone sulphur is grand, chlorine Fampridine sour, the ternary built of mesotrione is applied to preventing and kill off without relevant report of corn field annual weed.
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.
The present inventor is grand to thiophene ketone sulphur, the acid of chlorine Fampridine and salt compounds, mesotrione mixture conduct in-depth research, find that thiophene ketone sulphur is grand, the acid of chlorine Fampridine and salt compounds thereof, mesotrione mixture have Synergistic to respond to target weeds, especially have obvious Synergistic to respond to piemarker (Abutilontheophrasti), ivy glorybind (Calystegia hederacea).
Summary of the invention
