Abstract
本发明公开发明了一种噻呋酰胺油悬浮剂及其制备方法，是以噻呋酰胺、溶剂、增稠剂、分散剂、乳化剂、PH调节剂为原料，首先将噻呋酰胺、增稠剂经过预处理，然后将全部原料混合在一起搅拌，最后投入砂磨机中砂磨至粒径为5um以下，加入PH调节剂最后过滤即可。该产品经质量分析结果表明其有效成分分解率小于3％，悬浮率90％以上，低温储存无沉淀、结块及分层现象，其稳定性合格，54±2℃热储14d也无沉淀、结块及分层现象。该配方及其生产工艺简单，使用方便，全部采用国产助剂，生产成本低廉，未使用有机溶剂，大大减轻了环保压力，且对禾谷类作物水稻纹枯病、稻曲病、小麦纹枯病、散黑穗病防效较好。The present invention discloses a thiofluxamide oil suspension and a preparation method thereof, which uses thiofluxamide, a solvent, a thickener, a dispersant, an emulsifier, and a pH regulator as raw materials; firstly, the thiofluxamide, thickener The agent is pretreated, and then all the raw materials are mixed together and stirred, and finally put into a sand mill and sanded until the particle size is below 5um, and the pH regulator is added and finally filtered. The results of quality analysis of this product show that the decomposition rate of active ingredients is less than 3%, the suspension rate is over 90%, and there is no precipitation, agglomeration and stratification in low-temperature storage, and its stability is qualified. There is no precipitation, Agglomeration and delamination. The formula and its production process are simple, easy to use, all domestic additives are used, the production cost is low, and no organic solvent is used, which greatly reduces the pressure on environmental protection, and is effective against rice sheath blight, rice smut, and wheat sheath blight of cereal crops. , Scattered smut control effect is better.
Description
Technical field
The invention belongs to technical field of pesticide, be specifically related to a kind of thifluzamide oil-suspending agent and uses thereof and preparation method.
Background technology
Thifluzamide belongs to the thiazole amide broad-spectrum germicide, has strong interior conductivity and the long lasting effect of inhaling.Thifluzamide is the succinate dehydrogenase inhibitor, because fluorine-containing, its its competitiveness in biochemical pathway is very strong, in case be combined with regard to difficult recovery with substrate or enzyme.Thifluzamide all has activity to pathomycetes such as Rhizoctonia, Puccinia, Ustilago, Tilletia, corticium, nuclear cavity Pseudomonas, especially the fungus-caused disease of Basidiomycetes such as banded sclerotial blight, damping off etc. is had special efficacy.Especially thifluzamide has overcome many passivenesses of being used on the Vehicles Collected from Market preventing and treating smut to the unsafe characteristics of crop, prevents and treats in seed treatment and will bring into play larger effect aspect the systemic disease.General leaf surface treatment can effectively be prevented and treated rhizoctonia and the microbial disease of rust, can be used as the bactericide of cereal crop.Existing thifluzamide mostly is wetting powder, but this kind product produces a large amount of dust in processing, use procedure surrounding enviroment polluted greatly, and also unfavorable to operating personnel's health,
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the object of the present invention is to provide a kind of thifluzamide oil-suspending agent and uses thereof, have and use drug wastage little, environmental protection and efficient characteristics.
To achieve these goals, the technical solution used in the present invention is:
A kind of thifluzamide oil-suspending agent is characterized in that, includes following component (by weight percentage): thifluzamide 1-60%, vegetable oil 10%-50%, dispersant 1-5%, thickener 1-5%, emulsifier 10-40%.
As preferably, described vegetable oil is turpentine oil, soybean oil, oxidation soybean oil, peanut oil, corn oil, cottonseed oil, esterification soybean oil, esterification linseed oil, esterification sunflower oil, esterification cottonseed oil, esterification corn oil, esterification peanut oil, methyl oleate, the different monooctyl ester of lauric acid, oleic acid propylene glycol ester, laurel oleate, methyl laurate wherein any one or multiple mixture.
As preferably, described dispersant is wherein any one or the multiple mixture of metal carboxylate dispersant, lignin sulfonate dispersant, naphthalenesulfonate dispersant.
As preferably, described thickener is wherein any one or the multiple mixture of organobentonite, white carbon, aluminium-magnesium silicate, attapulgite.
As preferably, described emulsifier is that triethanolamine salt, polyoxyethylene sorbitol acid anhydride ester, alkylphenol polyoxyethylene, calcium dodecyl benzene sulfonate, phenethyl phenol polyethenoxy ether, the phenethyl APEO phosphate monoester of ethylene oxide propylene oxide block polymer, Nonyl pheno rice phosphate monoester and diester mixture obtains wherein any one or the multiple mixture in monoesters and diester mixture triethanolamine salt, the fatty alcohol-polyoxyethylene ether polycarboxylic acid salt's castor oil polyoxyethylene ether etc.
As preferably, described thifluzamide is selected from wherein any one or the multiple mixture of triethylamine, triethanolamine, acetic acid or phosphoric acid.
Further, a kind of purposes of thifluzamide oil-suspending agent is characterized in that, above-mentioned oil-suspending agent is used for control cereal crop rice sheath blight disease, false smut, wheat sharp eyespot and loose kernel smut.
Further, a kind of preparation method of thifluzamide oil-suspending agent is characterized in that, leaches after putting into the grinding machine sand milling after each component is mixed in proportion.
As preferably, described sand milling particle size is 5um.
The invention has the beneficial effects as follows:
Compared with prior art; the present invention is environment-friendly highly efficient, spectrum weed killer herbicide; can be extended on other efficient pesticides, bactericide, weed killer herbicide and the plant growth regulator by the present invention; improve the level of processing of China's formulations of pesticide; to improve the availability of pesticide active ingredient; reduce the use of auxiliary agent, organic solvent, auxiliary material; reduce to greatest extent the negative effect that agricultural chemicals brings environmental protection; promote simultaneously China's agricultural chemicals competitiveness in the international market, for country strives for foreign exchange.
The present invention can evenly mix dispersion with arbitrary proportion with oil, and is easy to use, and inconvenient contaminated environment can directly or after the dilution be sprayed.Preparation for processing can be made by wet pulverizing the suspension of high dispersive, continuous phase, and the average grain diameter of its particle has improved the suspensibility of particle in aqueous medium greatly generally below 3 microns, has strengthened the absorption of crops to medicament.
