Abstract
The present disclosure provides a pyraclostrobin microcapsule based on sodium alginate, which is prepared by mixing pyraclostrobin original drug dissolved in ethyl acetate, 1% aqueous sodium alginate solution, and 5% aqueous calcium carbonate solution at 25° C., and mixing the mixed solution with liquid paraffin containing 10% emulsifier A-110, maintaining a shear rate of 1000 r/min to emulsify for 10 min; using 87.5 mmol/L glacial acetic acid to reduce the pH of the mixed phase, such that the cross-linking reaction between ions can be formed into microcapsules; finally using pH 4.5 acetate buffer to wash and separate the microcapsule slurry, and then centrifuging and freeze-drying to prepare the pyraclostrobin SA microcapsules. The microcapsules prepared by the present disclosure have excellent formulation performance and can be used for the control of Fusarium pseudograminearum.
