Abstract
The invention relates to a weeding composition containing amicarbazone, fluroxypyr and nicosulfuron. The weeding composition comprises the amicarbazone, the fluroxypyr and the nicosulfuron as effective components, wherein the ratio of parts by weight of the amicarbazone to the fluroxypyr to the nicosulfuron is (1-5):(1-5):(1-5). The weeding composition has a synergistic interaction, and the effects of preventing and removing annual weeds are obviously superior to the effects of single use of each component; furthermore, the weeding spectrum is expanded, meanwhile, the dosage is reduced, the generation of drug resistance of weeds is delayed, and the environmental pollution is relieved.
Description
Technical field
The present invention relates to a kind of Herbicidal combinations containing amicarbazone and fluroxypyr and nicosulfuron, is with amicarbazone, fluroxypyr and nicosulfuron for active ingredient, for control of maize field annual weed.
Background technology
Chemical method weeding is agriculturally one of Main Means controlling weeds.In recent years, because some weed killer herbicide kind large area are used alone, a lot of weeds have been caused to develop immunity to drugs.Meanwhile, grass when weeds occur is mutually complicated, and multiple weeds are mixed raw, and single variety weed killer herbicide uses can not solve farmland weed, all can show defect in a certain respect and limitation.Variety classes weed killer herbicide mixture, have herbicidal spectrum wide, promote actual effect, delay herbicide resistance, time and labour saving advantage.
Amicarbazone belongs to triazolineone weed killer herbicide, efficient to broad leaved weeds such as Chenopodiaceae, Amaranthaceae, piemarkers, after susceptible weeds absorbs this medicine, destroys chlorophyllous formation by suppressing Single-chip microcomputer dual oxide enzyme, and the weeds chlorosis that causes being injured is withered.
Fluroxypyr is steroids inner sucting conduction type herbicide after seedling, is absorbed by plants very soon after medicine, makes sensitive plant occur the reaction of classical hormones class weed killer herbicide, plant deformity, distortion, finally withered.
Nicosulfuron belongs to sulfonylurea herbicide, efficient corn herbicide, and nicosulfuron uses after low dosage bud, effectively can prevent and kill off multiple annual gramineous weed in corn field, fraction broad leaved weed and sedge weed.It is absorbed rapidly by leaf and root, and conducted rapidly by xylem and phloem, by the synthesis suppressing acetolactate synthestase to stop branched-chain amino acid, use rear weeds to stop growing immediately, 4 ~ 5 days young leaves fade, downright bad, and progressively expand to whole plant, plant death in 20 ~ 25 days after process under general condition.Corn has good drug resistance to this medicine, occurs temporary transient chlorisis or slight hypoevolutism, but generally can recover rapidly and the not underproduction after process.
Variety classes weed killer herbicide mixture, have herbicidal spectrum wide, promote actual effect, delay herbicide resistance, time and labour saving advantage.Being screened by formulation of pesticide, can effectively improve actual control efficiency, reduce dosage, reduce costs, delay the generation of herbicide resistance, is the important means that agricultural synthesis is administered.The recipe determination of the present inventor to amicarbazone, fluroxypyr and nicosulfuron conducts in-depth research, find that amicarbazone, fluroxypyr and nicosulfuron carry out mixture, synergistic effect is had to corn field annual weed in certain mixed ratio scope, after further study, the present invention is completed.
Summary of the invention
The object of the invention is to solve in prior art to farmland weed develop immunity to drugs problem and actual control efficiency poor, provide a kind of efficient, low toxicity, quick-acting are good and the lasting period is long, are conducive to the composition pesticide of the farmland weed comprehensive regulation.Particularly for broad leaved weed, comparatively serious corn field occurs, the active ingredient amicarbazone in Herbicidal combinations of the present invention and fluroxypyr strengthen the control efficiency to broad leaved weed greatly.On this basis, then add nicosulfuron and then effectively can prevent and treat most of grassy weed.
Technical scheme: a kind of corn field postemergence weed control composition, active ingredient is amicarbazone, fluroxypyr, nicosulfuron, the ratio of weight and number of amicarbazone, fluroxypyr and nicosulfuron is 1 ~ 5:1 ~ 5:1 ~ 5, the weight summation percentage by weight in the composition of amicarbazone, fluroxypyr and nicosulfuron is 5% ~ 95%, and all the other are agriculturally acceptable insecticides adjuvant.
Described Herbicidal combinations according to well known to a person skilled in the art method, can be selected suitable pesticidal preparations auxiliary element, 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 auxiliary element that the present invention uses comprises wetting agent, stabilizing agent, dispersant, disintegrant, thickener, pH adjusting agent, defoamer, antifreezing agent, filler etc., be all auxiliary agent conventional in Pesticide formulation, concrete composition and consumption are determined by test according to recipe requirements.
Herbicidal combinations provided by the invention, is applicable to corn field seedling rear defence except annual weed.
The frequency of administration of Herbicidal combinations 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.
Product described in the invention can the form of finished product preparation provide, and namely in composition, each material mixes, and the composition of composition also can the form of single dose provide, and directly mixes in tank or bucket, be then diluted to required concentration before using.
Herbicidal combinations provided by the invention has following beneficial effect:
1, Herbicidal combinations provided by the invention, obvious synergy or summation action is shown in certain ratio range, the control efficiency of composition to weeds is significantly improved than single dose, reduce the using dosage of agricultural chemicals, decrease times for spraying, reduce drug cost, decrease the adverse effect of agricultural chemicals to ecotope.
2, Herbicidal combinations provided by the invention, the combination of three kinds of effective ingredients, expands herbicidal spectrum, and a drug can solve weed problem, compensate for defect when single dose uses and limitation.
3, Herbicidal combinations provided by the invention, three kinds of effective ingredient mechanism of action are not quite identical, can overcome the shortcoming that long-term single use easily produces resistance, extend the service life of medicament, to the comprehensive regulation important in inhibiting of Weed Resistance.
4, Herbicidal combinations provided by the invention, drug effect plays rapidly, and the lasting period is long, and use cost is low, easy to use, time saving and energy saving, and it applies huge economic benefit and social benefit.
