Abstract
The invention discloses a pesticide composition containing topramezone, thiencarbazone-methyl, and a benzonitrile herbicide. Active ingredients of the pesticide composition are topramezone, thiencarbazone-methyl, and the benzonitrile herbicide; and the benzonitrile herbicide is one selected from bromoxynil octanoate or bromoxynil. The pesticide composition possesses excellent synergistic effects; prevention effects on corn field annual weed are obviously better than prevention effects of the single ingredients; using amount of the pesticide composition is obviously less than using amount of the single ingredients; weed control spectrum is enlarged; generation of weed drug resistance is delayed; and environmental pollution is reduced.
Description
Technical field
The invention belongs to technical field of pesticide, be specifically related to the composition pesticide that Synergistic that a kind of, benzene nitrile herbicide grand with benzene pyrazoles humulone, thiophene ketone sulphur is active ingredient responds, be applicable to prevent and kill off 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.
Benzene nitrile herbicide is contact killing type weed killer herbicide, only limited conduction can be carried out after being absorbed by grass cutting blade, main inhibited photosynthesis, impel blade chlorisis and produce withered spot, be mainly used in that control wheat, corn field annual broadleaf weed store as pivot, black nightshade, Siberian cocklebur, field bindweed, dayflower, amaranth, knotweed, lamb's-quarters etc., in soil, the half life period is 15 days, to succession crop safety.
By the screening of different pesticide species compounded formula, select outstanding formula and effectively can improve actual control efficiency to disease, worm, crop smothering, reduce dosage, reduce costs, delaying disease, worm, the drug-fast generation of crop smothering, is the important means of agriculturally disease, worm, the crop smothering comprehensive regulation.The present inventor is grand to benzene pyrazoles humulone, thiophene ketone sulphur, benzene nitrile herbicide (one in bromoxynil octanoate or Brominal) mixture conducts in-depth research, find that three's mixture has Synergistic to respond to target weeds, especially have obvious Synergistic to respond to lady's-grass (Digitaria sanguinalis), piemarker (Abutilon theophrasti).
Benzene pyrazoles humulone, thiophene ketone sulphur are grand, the ternary built of bromoxynil octanoate or Brominal 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 the composition pesticide 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 benzene nitrile herbicide, active ingredient is that benzene pyrazoles humulone, thiophene ketone sulphur are grand, benzene nitrile herbicide, 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 benzene nitrile herbicide 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.
The invention has the advantages that: the present invention expands herbicide spectrum, composition has Synergistic response to target, especially to lady's-grass (Digitaria sanguinalis), piemarker (Abutilontheophrasti), there is 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), piemarker (Abutilontheophrasti) corn field that is advantage weeds, has positive effect for the corn field weed comprehensive regulation.
