Abstract
The invention discloses a sulfometuron methyl composite herbicide. The sulfometuron methyl composite herbicide is characterized in that sulfometuron methyl and 2-Methyl-4-chloro compounds are taken as main effective components, are compounded according to a specified proportion and are used for preventing and killing off annual and perennial gramineous weeds and broadleaf weeds. The composite herbicide solves the problem that the existing sulfometuron methyl composite herbicide has poor control efficiency and fast-acting property to worst weeds, and the use cost is reduced.
Description
Technical field
The present invention relates to a kind of weed killer herbicide, particularly relate to a kind of by sulfometuronmethyl and 2 first 4 chlorine class Herbicidal combinations for preventing and kill off annual, perennial grassy weed and broad leaved weed.
Background technology
Sulfometuronmethyl (Sulfometuron-Methyl) is sulfonylurea herbicide, suppresses branched-chain amino acid synthesis, thus suppresses the cell division of plant strain growth end, stops weed growth downright bad to chlorosis.Sulfometuronmethyl is steriland herbicide before bud, after bud, be applicable to forest and prevent and kill off annual and perennial grassy weed and broad leaved weed, or open up forest isolation strip, forest land cleaning after lumbering, before wasteland is cultivated, leisure uncultivated area, the wasteland weeding of roadside, road is gone out filling, as sheep lance, Common Goldenrod Herb, earth almona, Aleppo grass, artemisiifolia etc.
2 first 4 chlorine (MCPA), chemical name 2-methyl-4-chlorophenoxyacetic acid sodium.2 first 4 chlorine are phenoxy acetic acid class selectivity hormone herbicide, and medicine is absorbed by the root of plant, stem, leaf, and can destroy the conducting tissue of dicotyledon, making to grow is interfered, cauline leaf distortion, and basal part of stem expands thicker or cracking.Convexutricle sedge herb can be prevented and kill off, broad leaved weed and the sedge weeds such as difformed galingale herb, Monochoria vaginalis, water three-coloured amaranth, wild arrowhead, flat bar deer grass, knotweed, common vetch, clearvers, Herba Ranunculi Japonici, shepherd's purse, dandelion, Japanese Cayratia Herb, field thistle.Stable performance, Be very effective.
Sulfometuronmethyl single dose herbicidal effect is better, and the lasting period is long, but quick-acting is poor, and dosage is comparatively large, and use cost is high.In order to overcome the above problems, seen the report of sulfometuronmethyl and glyphosate compound herbicide, but the two multiple mating section malignant weed is as not good in the preventive effect such as eleusine indica, knotweed, and quick-acting be bad, therefore not be used widely.
Summary of the invention
The technical problem to be solved in the present invention is for the deficiencies in the prior art, proposes a kind of compound herbicide, and effectively can prevent and kill off annual, perennial grassy weed and broad leaved weed, comprise the malignant weed such as eleusine indica and knotweed, and quick-acting is good, cost is low.
A kind of compound herbicide provided by the invention, with sulfometuronmethyl and 2 first 4 chlorine class weed killer herbicides for active component, its total content is between 0.5% ~ 95.0%, and sulfometuronmethyl and 2 first 4 chlorine class mixture of herbicides ratios between 1:60 ~ 60:1, and can comprise the auxiliary element of agricultural chemicals.
Described 2 first 4 chlorine class weed killer herbicides comprise one or more compositions in 2 first 4 chloric acid, 2 first 4 chlorine sodium salts, 2 first 4 oronain salt, 2 first 4 chlorine isopropyl amine salts, 2 first 4 chlorine dimethylamine salts, 2 first 4 chlorine sylvite etc.
In described compound herbicide composition, sulfometuronmethyl weed killer herbicide and the preferred ratio of 2 first 4 chlorine class mixture of herbicides are 1:9 ~ 9:1.
Described compound herbicide, can be solid pharmaceutical preparation and liquid preparation; Comprise: aqua, soluble granula, soluble liquid, soluble powder, suspending agent, wetting powder, microemulsion, aqueous emulsion, dispersible the multiple dosage form product such as granula, effervescent tablet; Wherein be preferably suspending agent.
Compound herbicide provided by the invention, preferred dosage form is suspending agent, and active ingredient comprises sulfometuronmethyl, 2 first 4 chlorine class agricultural chemicals, and auxiliary agent comprises: wetting agent, dispersant, preservative, thickener, antifreezing agent and water.
Above-mentioned compound herbicide, its suspending agent constituent and mass percent thereof are: sulfometuronmethyl 0.5% ~ 90.0%, 2 first 4 chlorine 0.5% ~ 50.0%, wetting agent 1.0% ~ 5.0%, dispersant 1.0% ~ 10.0%, thickener 0% ~ 2.0%, antifreezing agent 0% ~ 5.0%, preservative 0% ~ 2.0%, water complements to 100%.
Described wetting agent is one or more in calcium dodecyl benzene sulfonate, neopelex, lauryl sodium sulfate, polyoxyethylene nonylphenol ether, fatty alcohol-polyoxyethylene ether, styrene phenol formaldehyde resin polyoxyethylene poly-oxygen propylene aether.
Described dispersant is one or more of alkylbenzenesulfonate, lignosulfonates, alkyl ethyl sulfonate, alkyl naphthalene formaldehyde condensate sulfonates, polyoxyethylene nonylphenol ether etc.
Described thickener is one or more in xanthans, aluminium-magnesium silicate, gum Arabic, sodium carboxymethylcellulose.
Described antifreezing agent is one or more in glycerine, ethylene glycol, propane diols, glycerine.
Described preservative is one or more in Sodium Benzoate, potassium sorbate.
Advantage of the present invention: compare with glyphosate compound herbicide with existing sulfometuronmethyl, weed killer herbicide of the present invention has obvious advantage, and it is mainly manifested in:
(1) compound herbicide of the present invention is while the removing activity not changing sulfometuronmethyl and 2 first 4 chlorine class weed killer herbicides, carries out composite, reach the object of synergy by the two according to rational ratio;
(2) in documents, sulfometuronmethyl and glyphosate answer mating section malignant weed if the preventive effect such as eleusine indica, knotweed is less than 80%, and the present invention adds 2 first 4 chlorine class weed killer herbicide preventive effects in sulfometuronmethyl reaches more than 90%, solve the problem that malignant weed is difficult to prevent and kill off;
(3) sulfometuronmethyl and 2 first 4 chlorine, two kinds of mixture of herbicides can improve the quick-acting of weed killer herbicide;
(4) herbicidal composition of the present invention reduces use cost, easy to utilize.
