Abstract
The present invention relates to the field of farm chemical and the herbicide composition of acyl aniline and sulfony urea of the present invention is used to prevent and kill weeds in rice field.
Description
The invention belongs to pesticide field, specifically anilide and sulfonylurea herbicide composition.
Along with China's agricultural development, the extensive use of chemical herbicide, great changes have taken place in original weed community.Main weeds originally becomes less important weeds, and relative less important weeds rise to main weeds, so just requires the manufacturing enterprise of agricultural chemicals to produce and meets the weed killer herbicide that present control of weeds requires.The medicament of Ying Yonging has mefenacet, Yu Nongle, gram not to have track etc. in the market, but because all there are some problems in they in application time and medicament price, so popularization all has difficulties on the market.
The objective of the invention is to practical problem, proposed a kind of new herbicidal composition at weed killer herbicide supply and demand in the agricultural production of present China.
Compound herbicide of the present invention contains acyl aniline herbicide and sulfonylurea herbicide.The acyl aniline herbicide of indication of the present invention can be mefenacet (MEFENACET) and other acyl aniline herbicide.Furtherly, compound herbicide of the present invention includes the mefenacet of 1-99% and the pyrazosulfuron of 0.2-90%.
Compound herbicide of the present invention can also be mixed with into preparation with other agricultural chemicals such as weed killer herbicide, insecticide, bactericide and safener, fertilizer, growth regulator.
Utilize the said weed killer herbicide of the invention described above, be equipped with the known auxiliary agent of those skilled in that art (comprising solvent (filler), synergist etc.), can be made into the compound herbicide of the multiple formulation of the present invention.The content range of pyrazosulfuron is 0.2-90% in the formulation, and the content range of mefenacet is 1-99%, and mefenacet and pyrazosulfuron can arbitrary proportions composite (pyrazosulfuron 0.2-90%+ mefenacet 1-99%).

B: dry suspending agent is with former the effective elements of the medicine, wetting agent, disintegrant, dispersant and adhesive, by forming with the water mixing granulation.Be used for wetting agent of the present invention and can be among the anionic surfactant such as sodium alkyl sulfate, sodium alkyl benzene sulfonate and benzene sulfonic acid sodium salt one or more, its consumption is 0.1-10%.Be used for disintegrant of the present invention and can be among starch and derivative, alginic acid and salt and the clay etc. one or more, consumption is 0.1-20%.Be used for formaldehyde condensation products that dispersant of the present invention and adhesive are lignosulfonates, alkylbenzenesulfonate, alkylnaphthalene sulfonate and one or more goods and materials among the polycarboxylic acid surfactant.Common consumption 5-30%.
C: missible oil is by active ingredient is dissolved in one or more organic solvents.Being used for solvent of the present invention can be pentane, ether, methyl alcohol, ethyl acetate, chloroform, chloromethanes, dimethyl sulfoxide (DMSO), dimethylbenzene, one or more compositions among the toluene etc.; Be used for emulsifier of the present invention and be one or more materials among fatty alcohol polyglycol ether sulphate, fatty acid amide N methyl taurine sodium salt, the sodium sulfate of polyethenoxy ether of fatty alcohol; usually consumption is 0.1-30%; the present invention also includes penetrant t; common consumption 0.1-10%; benefit farming oil; azone, consumption 0.1-20% usually.
D: aqueous suspension agent be with pyrazosulfuron and mefenacet by after adding synergist, auxiliary agent, the preparation of making through ball milling, sand milling.Auxiliary agent of the present invention can be one or more materials among fatty alcohol polyglycol ether sulphate, fatty acid amide N-methyl ox acid iodide sodium salt, sodium sulfate of polyethenoxy ether of fatty alcohol, alkylphenol polyoxyethylene sulphate, alkylphenol polyoxyethylene, the triphen ethyl-phenol polyoxyethylene, usually consumption 0.1-30%; The present invention also contains penetrant t, usually consumption 0.1-10%; Ethylene glycol, consumption 0.1-10% usually; CMC, consumption 0.1-10% usually; Xanthans, 0.1-10%; Tributyl phosphate, 0.1-20%.
E: finish is made by former medicine, surfactant adding mineral oil or vegetable oil.Surfactant of the present invention comprises dioctyl phthalate, alcohol, fatty acid, the liquid ester class of alicyclic ring alcohol, as repefral, butyl ester, diisobutyl ester, two laruyl alcohol esters, two cyclic esters, two cyclohexanols and two ring monooctyl esters etc., also available C6-C10 carboxylic acid such as positive acetate, capric acid, n-nonanoic acid, benzoic acid and ester are as benzylacetic acid ester, ethyl acetate, ethyl pelargonate, methyl benzoate or ethyl ester etc., consumption 0.1-30% usually.Can be as emulsifier: fatty alcohol polyglycol ether sulphate, fatty acid amide N methyl taurine sodium salt, sodium sulfate of polyethenoxy ether of fatty alcohol; alkylphenol polyoxyethylene sulphate, alkylphenol polyoxyethylene, sodium alkyl benzene sulfonate-calcium; sodium lignin sulfonate-calcium, consumption 0.1-30% usually.
F: pulvis is by with active ingredient and finely divided property solid matter such as talcum, and natural clay such as kaolin, nation's soil, precipitated calcium carbonate and pyrophyllite or diatomite, white carbon black grind together to be made, and supplies 100%.
The optimum ratio of compound herbicide of the present invention is (percentage by weight):
