The weeding composition comprises an active ingredient A and an active ingredient B which are used in a weeding effective amount, wherein the active ingredient A is the triazophone, and the active ingredient B is selected from one or more of the following compounds: fentrazamide, anilofos, mefenacet. The composition can effectively prevent and kill barnyard grass, rice straw, moleplant seed and other weeds in crops, and has the characteristics of expanding a weed control spectrum, reducing application amount, being safe to crops, generating a synergistic effect, solving resistant weeds and the like.
Description
The application is a divisional application of Chinese patent application with the application date of 09 and 19 in 2017, the application number of 201710852148.1 and the invention name of 'a weeding composition containing triazophodim and application thereof'.
Technical Field
The invention belongs to the field of pesticides, and particularly relates to a weeding composition containing triazophos-ethyl and application thereof.
Background
Chemical weeding is the most economic and effective means in preventing and removing weeds in farmlands, but the problems of drug resistance and resistance evolution of weeds and the like are easily caused by using a single variety or a single action mode of chemical herbicide continuously at a high dose for a long time. The reasonable compounding or mixing of the herbicide compound has the advantages of expanding the weed spectrum, improving the control effect, delaying the occurrence and development of drug resistance and drug resistance of weeds and the like, and is one of the most effective methods for solving the problems.
Patent CN105724390A discloses various herbicidal compositions containing pyrazole compounds, which comprise the active ingredient triazasulam, the chemical structural formula of which is
The HPPD inhibitor herbicide is a newly developed HPPD inhibitor herbicide for treating postemergence stems and leaves of paddy fields, has excellent biological activity, can effectively prevent and kill various malignant weeds in the paddy fields, but does not record that all combinations can generate synergistic effect.
Therefore, the development of a weeding composition variety which has high safety and wide weed control spectrum, can produce synergistic effect and solve the problem of resistant weeds is urgently needed in production.
Disclosure of Invention
In order to solve the problems in the prior art, the invention provides a weeding composition containing triazophos-cotrione and application thereof, wherein the composition can effectively prevent and kill barnyard grass, moleplant seed and other weeds in crops, and has the characteristics of enlarging a weeding spectrum, reducing application amount, being safe to crops, generating synergistic effect, solving resistant weeds and the like.
A weeding composition containing triazophos-cotrione comprises a herbicidally effective amount of an active ingredient A and an active ingredient B, wherein the active ingredient A is triazophos-cotrione, and the active ingredient B is selected from one or more of the following compounds: fentrazamide, anilofos, mefenacet.
Wherein the weight ratio of the active ingredients A and B is 1:60-60:1, preferably 1:50-50:1 and 1:40-40:1, more preferably 1:30-30:1 and 1:20-20:1, and further preferably 1:10-10: 1.
Preferably, the weight ratio of A to fentrazamide is 1:30-12:1
The weight ratio of the A to the anilofos is 1:36-12:1
The weight ratio of the A to the mefenacet is 1:24-2: 3.
The mass percentage of A, B in the weeding composition accounts for 1-95% of the total amount, and preferably 10-80%.
The herbicide composition further comprises a safener C, and the safener C is selected from one or more of the following compounds:
c1: diphenyl oxazole acid (CAS: 163520-33-0)
C2: cyprosulfamide (CAS number: 221667-31-8)
C3: pyrazolyl cloquintocet-mexyl (CAS number: 135590-91-9)
C4: cloquintocet-mexyl (CAS number: 99607-70-2)
C5: gibberellic acid (CAS number: 77-06-5)
C6: furilazole (CAS number: 121776-33-8)
C7: metcamifen (CAS number: 129531-12-0).
The weeding composition also comprises conventional auxiliaries which comprise a carrier and a surfactant.
The term "carrier" herein denotes an organic or inorganic, natural or synthetic substance. They facilitate the application of the active ingredient, the carrier being generally inert and must be agriculturally acceptable, in particular for the treated plant. The carrier may be a solid, such as a clay, natural or synthetic silicate, silica, resin, wax, solid fertilizer, or the like; or liquids such as water, alcohols, ketones, petroleum distillates, aromatic or waxy hydrocarbons, chlorinated hydrocarbons, liquefied gases, etc.
Surfactants may include emulsifying, dispersing or wetting agents, which may be ionic or non-ionic. Examples which may be mentioned are salts of polyacrylic acids, lignosulphonates, salts of phenolsulphonic or naphthalenesulphonic acids, polymers of ethylene oxide with aliphatic alcohols or with aliphatic acids or with aliphatic amines and substituted phenols, in particular alkylphenols or arylphenols, sulphosuccinates, taurine derivatives, in particular taurine alkyl esters, and phosphoric esters of alcohols or polyhydroxyethylated phenols, alkylsulfonates, alkylarylsulphonates, alkylsulfates, lauryl ether sulphates, fatty alcohol sulphates, and sulphated hexadec, heptadeca-and octadecanols and sulphated fatty alcohol glycol ethers, and furthermore condensates of naphthalene or naphthalenesulphonic acids with phenol and formaldehyde, polyoxyethylene octylphenyl ether, ethoxylated isooctylphenol, octylphenol or nonylphenol, alkylphenyl polyglycol ethers, tributylphenyl polyglycol ether, tristearylphenyl polyglycol ether, polystearylphenyl polyglycol ether, Alkylaryl polyether alcohols, alcohol and fatty alcohol/ethylene oxide condensates, ethoxylated castor oil, polyoxyethylene alkyl ethers, ethoxylated polyoxypropylene, lauryl alcohol polyglycol ether acetal, sorbitol esters, lignosulfite waste liquors, and also proteins, denatured proteins, polysaccharides (e.g. methylcellulose), hydrophobically modified starches, polyvinyl alcohols, polycarboxylates, polyalkoxylates, polyvinylamines, polyvinylpyrrolidone and copolymers thereof. At least one surfactant is required to be present to facilitate dispersion of the active ingredients in water and to facilitate their proper application to the plant.
The compositions may also contain various other components such as protective colloids, binders, thickeners, thixotropic agents, penetrants, stabilizers, chelating agents, dyes, colorants, and polymers.
The compositions of the present invention may be diluted or used directly by the user prior to use. The formulation can be prepared by conventional processing methods, i.e., mixing the active substance with a liquid solvent or solid carrier, and adding one or more surfactants such as dispersants, stabilizers, wetting agents, binders, defoamers, etc.
The specific preparation of the weeding composition is dispersible oil suspending agent, water suspending agent, suspoemulsion, missible oil, water dispersible granule (dry suspending agent), emulsion in water and microemulsion.
In short, the compositions of the present invention may be mixed with solid and liquid additives conventionally used in prior art formulations.
