Micro-emulsion for killing Monilinia fructicola and preparation method thereof

The present invention relates to a process for preparing microemulsions and Monilinia killing bacteria. Peach brown rot fungi to kill micro-emulsion of the present invention, the active ingredients, solvents, emulsifiers, antifreeze and water, the active ingredient is salicylic acid and berberine. The solvent is preferably 95% or more volume percent ethanol. The emulsifier is preferably Tween 80. The cryoprotectant is preferably 5% g / mL of the aqueous ethylene glycol solution. The method of the present invention are prepared: berberine salicylic acid and mixed, solvent is added, dissolved by heating, to obtain an active ingredient solution; emulsifier added to the solution and dissolved under ultrasonic conditions, water bath and stirred, to obtain effective emulsion components; antifreeze added to the emulsion, the water bath and stirred to give a peach brown rot fungi to kill micro-emulsion. Microemulsions of the present invention can Qiang Lie inhibit Monilia cinerea and broad-spectrum antimicrobial, while a stable, efficient, and low cost.
