Abstract
The invention discloses a triflumizole suspending agent and a preparation method thereof. The suspending agent contains triflumizole as the active component and is prepared by the steps of adding a wet dispersing agent, an emulsifier, antifreeze, a thickener, a pH regulator, preservative, a defoamer, and water into a sand mill and grinding into a mixture with an average grain size of 2-3 micrometers. The invention provides a novel environmental-friendly water-based triflumizole agent, which reduces environmental pollution and energy consumption during production process, is effective and safe, and satisfies the requirements of agricultural production.
Description
Technical field
The present invention relates to a kind of fluorine bacterium azole suspending agent and preparation method thereof.
Background technology
Fluorine bacterium azoles is a kind of ergosterol biosynthesis inhibitor, wide-spectrum bactericide with interior suction, treatment, eradicant action, be mainly used in wheat class, vegetables, fruit tree, crop such as melon prevents and treats powdery mildew, rust, scab, and is and also effective to rice blast, bakanae disease, oriental sesame leaf rot, tea tree anthracnose etc.The preparation of relevant fluorine bacterium azoles list agent has wetting powder, microemulsion, fumicants, water dispersible granules etc. in the market.That the fluorine bacterium azoles list agent of these formulations such as wetting powder, microemulsion, fumicants exist is big for environment pollution, water dispersible granules exists shortcomings such as power consumption of polymer processing height, and the suspending agent of relevant fluorine bacterium azoles yet there are no report.The invention reside in provides a kind of fluorine bacterium azoles new environmentally-friendly water-basedization formulation, has overcome the shortcoming of existing formulation.
Summary of the invention
One of technical problem to be solved by this invention is to provide at shortcoming such as existing big for environment pollution, the preparation processing energy consumption height of the existing formulation of fluorine bacterium azoles a kind of, fluorine bacterium azole suspending agent that power consumption of polymer processing low little to environmental influence.
Two of technical problem to be solved by this invention is to provide the preparation method of above-mentioned fluorine bacterium azole suspending agent.

Water surplus.
Wetting dispersing agent of the present invention is preferably one or more mixing in sodium lignin sulfonate, EO-PO block copolymer, alkylphenol-polyethenoxy phosphate, CMC, polyvinyl alcohol, polyvinylpyrrolidone, the lauryl sodium sulfate.
Described emulsifier is preferably: one or more mixing among agricultural newborn 500#, 600#, 700#, 602,603,790,1303,1601,1603,2020,2201,0201B, 0203B, the 6202B.
Described thickener is xanthans or Magnesiumaluminumsilicate.
Described antifreezing agent is ethylene glycol, propane diols or glycerine.
Described preservative is an organic acid.Described organic acid is preferably citric acid, benzoic acid.
Described defoamer is organic silicone or ester ethers defoamer.Described ester ethers defoamer is preferably alkylphenol polyoxyethylene.
The preparation method of the fluorine bacterium azole suspending agent of second aspect present invention, it is characterized in that, after by proportion relation fluorine bacterium azoles, wetting dispersing agent, emulsifier, thickener, antifreezing agent, preservative, defoamer and water being mixed, regulate the pH value with the pH regulator agent and to 3-11, shear; Shearing laggard sand mill sand milling to average grain diameter 2-3 micron makes.
Described pH regulator agent is acid or alkali.
Fluorine bacterium azole suspending agent of the present invention is compared with the existing formulation of fluorine bacterium azoles, and effect has significant difference.
Embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer and more definite, below in conjunction with example the present invention is done to describe in further detail, describe only limiting to better explain the present invention herein, and be not used in qualification the present invention.Embodiment provides the prescription of part fluorine bacterium azole suspending agent for the technical staff, and the technical staff can prepare with reference to these prescriptions.
Embodiment 1
With the fluorine bacterium azoles (95%, Shengnong Biological-Chemical Products Co., Ltd., Shanghai) of 30 weight portions, 11.7 weight portion auxiliary agents (wherein: alkylphenol-polyethenoxy phosphate: 6%; Emulsifier 600 #:2%; Glycerine: 3%; Xanthans: 0.2%; Organic silicone: 0.4%; 0.1%), water complements to 100 parts, regulates pH value to 6.5 back with the pH regulator agent and mixes shearing benzoic acid:, shear laggard sand mill sand milling to particle mean size 2-3 micron and promptly make 30% fluorine bacterium azole suspending agent.
Embodiment 2
Fluorine bacterium azoles biological activity determination result:
For the examination target is powdery mildew of cucumber;
Test method adopts spore suspension spray inoculation method to measure the biologically active of medicament.With the 30% fluorine bacterium azole suspending agent of embodiment 1 and contrast medicament 50% thiram wettable powder (medicament of market conventional control powdery mildew of cucumber) be mixed with 100,50,25,12.5 respectively, 6.25mg/L concentration medicament, the processing of spraying, four repetitions are established in every processing.Carry out the classification investigation according to the contrast incidence,, refer to calculate preventive effect % by disease with reference to " the initiative pesticide bioactivity is estimated SOP " bactericide volume.
Investigation method and grade scale:
0 grade: anosis;
1 grade: lesion area accounts for below 5% of one-piece blade area;
3 grades: lesion area accounts for 6%～10% of one-piece blade area;
