Abstract
The invention discloses a pesticide composition containing topramezone, thiencarbazone-methyl and mesotrione. Active ingredients are topramezone, thiencarbazone-methyl and mesotrione. The pesticide composition has remarkable synergistic effects, has an obviously more excellent effect of preventing and removing annual weeds in cornfields than each single ingredient. Dosage of the active ingredients of the composition is obviously reduced in comparison with dosage of a single ingredient. In addition, weed control spectrum is broadened, weed resistance to herbicides is delayed, and environmental pollution is mitigated.
Description
Technical field
The invention belongs to technical field of pesticide, be specifically related to Synergistic response composition pesticide that a kind of, mesotrione grand with benzene pyrazoles humulone, thiophene ketone sulphur is active ingredient and preventing and kill off the application in corn field annual weed.
Background technology
Benzene pyrazoles humulone (topramezone), for cauline leaf inorganic agent after pyrazolone seedling, can be absorbed by root, young stem and leaf, by suppressing 4-medical midbodies of para (ortho)-hydroxybenzoic acetone acid esters dual oxide enzyme (4HPPD) in plastoquinone biosynthesis, the synthesis of remote-effects carotenoid, the synthesis of interference chloroplast and function, finally cause serious albefaction (due to chlorophyllous degraded), corn is had to the selectivity of height, be mainly used in preventing and kill off corn field annual gramineous weed and part broad leaved weed.
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.
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.
The present inventor is grand to benzene pyrazoles humulone, thiophene ketone sulphur, mesotrione mixture conducts in-depth research, find that benzene pyrazoles humulone, thiophene ketone sulphur are grand, mesotrione mixture has Synergistic to respond to target weeds, especially have obvious Synergistic to respond to lady's-grass (Digitaria sanguinalis), acalypha copperleaf (Acalypha australis).Benzene pyrazoles humulone, thiophene ketone sulphur are grand, the ternary built of mesotrione is without relevant report.
Summary of the invention
The object of the invention is to solve when prior art Pesticides single dose is used alone the problem that corn field weed easily develops immunity to drugs and actual control efficiency is poor, a kind of efficient, wide spectrum, economy, safety are provided, are conducive to composition pesticide and the application thereof of the corn field weed comprehensive regulation.
Technical scheme of the present invention is: a kind of containing benzene pyrazoles humulone and thiophene ketone sulphur is grand and the composition pesticide of mesotrione, active ingredient is that benzene pyrazoles humulone, thiophene ketone sulphur are grand, mesotrione, benzene pyrazoles humulone percentage by weight is in the composition 0.1% ~ 10%, the grand percentage by weight in the composition of thiophene ketone sulphur is 0.1% ~ 15%, the percentage by weight of mesotrione in Herbicidal combinations is 0.1% ~ 50%, and all the other are allow in agricultural chemicals to use and acceptable auxiliary element.
Described composition pesticide according to well known to a person skilled in the art method, 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 production technology of the various application forms of described composition pesticide all belongs to existing known technology, does not repeat them here.
Composition pesticide provided by the invention, is applicable to prevent and kill off corn field annual weed.
The frequency of administration of composition pesticide 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
Triple combination of the present invention (i.e. the grand mesotrione of benzene pyrazoles humulone thiophene ketone sulphur) expands herbicide spectrum, composition has Synergistic response to target, especially to lady's-grass (Digitaria sanguinalis), acalypha copperleaf (Acalypha australis) has the response of obvious Synergistic, excellent fix can be provided for preventing and kill off of corn field annual weed, especially lady's-grass (Digitaria sanguinalis), the corn field that acalypha copperleaf (Acalypha australis) is advantage weeds, for the corn field weed comprehensive regulation, there is positive effect.
