Microcapsulation of biocontrol agent will facilitate long-term storage and maintenance of the biological activities of antagonistic bacteria, including enzyme activity, antifungal activity of metabolites, and the biocontrol activity. The effect of media and coating materials on the biological activities of bacterial microcapsule will be examined to achieve an optimal formulation for the biocontrol of foliar fungal diseases of plants. In addition, the efficacy of solid support for application of microcapsules of antagonistic bacteria will be investigated for better plant protection in the soil environment and the improvement of disease and pest problems of plants.拮抗細菌臘狀芽孢桿菌膠囊化囊壁材質噴霧乾燥乳化生物防治活性Antagonistic bacteriaBacillus cereusmicroencapsulationcoating materialsspraying dryemulsificationbiocontrol activity
