Abstract
The invention discloses an herbicide composition comprising thiencarbazone-methyl, aminopyralid and bromoxynil octanoate. The effective components of the herbicide composition are thiencarbazone-methyl, aminopyralid and bromoxynil octanoate. The herbicide composition has a significant synergistic effect. A maize field annual weed controlling and removing effect of the herbicide composition is obviously better than that of each component applied independently. The dose of the effective components of the composition is substantially reduced than that of all the components applied independently, and the herbicidal spectrum is expanded. With the herbicide composition, the generation of weed drug resistance is retarded, and the environment pollution is alleviated.
Description
Technical field
The invention belongs to technical field of pesticide, be specifically related to a kind of grand with thiophene ketone sulphur, that chlorine Fampridine sour, bromoxynil octanoate is active ingredient Synergistic and respond composition pesticide, be applicable to prevent and kill off corn field especially with the corn field annual weed that green foxtail, ivy glorybind are advantage weeds.
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.
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.
The present inventor is grand to thiophene ketone sulphur, chlorine Fampridine sour, bromoxynil octanoate mixture conducts in-depth research, find that thiophene ketone sulphur is grand, chlorine Fampridine sour, bromoxynil octanoate mixture has Synergistic to respond to target weeds, especially has obvious Synergistic to respond to green foxtail (Setaria viridis), ivy glorybind (Calystegia hederacea).Thiophene ketone sulphur is grand, chlorine Fampridine sour, the ternary built of bromoxynil octanoate is applied to preventing and kill off without relevant report of corn field annual weed.
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 composition pesticide, active ingredient is that thiophene ketone sulphur is grand, chlorine Fampridine sour, bromoxynil octanoate, the grand percentage by weight in the composition of thiophene ketone sulphur is 0.1% ~ 20%, chlorine Fampridine acid percentage by weight is in the composition 0.1% ~ 30%, bromoxynil octanoate percentage by weight is in the composition 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.
(namely thiophene ketone sulphur grand chlorine Fampridine acid bromoxynil octanoate expands herbicide spectrum to triple combination of the present invention, composition has Synergistic response to target, especially to green foxtail (Setaria viridis), ivy glorybind (Calystegia hederacea) has the response of obvious Synergistic, excellent fix can be provided for preventing and kill off of corn field annual weed, especially green foxtail (Setaria viridis), the corn field that ivy glorybind (Calystegiahederacea) is advantage weeds, for the corn 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.
Assays Example 1: thiophene ketone sulphur is grand, chlorine Fampridine acid, bromoxynil octanoate and the composite Toxicity Determination to green foxtail (Setaria viridis), ivy glorybind (Calystegia hederacea) test.
Evaluate weed killer herbicide associated form (NY/T 1155.7-2006) according to Colby method, its formula is as follows:
In formula:
A be thiophene ketone sulphur grand alone with certain dosage time fresh weight inhibition to target weeds;
B be the acid of chlorine Fampridine alone with certain dosage time fresh weight inhibition to target weeds;
C be bromoxynil octanoate alone with certain dosage time fresh weight inhibition to target weeds;
N is the weed killer herbicide kind number of mixture;
E
0for thiophene ketone sulphur is grand, the acid of chlorine Fampridine, bromoxynil octanoate three kinds of pharmacy mix time theoretical value to target weeds fresh weight inhibition;
