Abstract The application of biopesticides in many industries can be hampered due to their high volatility, susceptibility degradation when exposed light or microbial activity, and reduced activity stressful environmental conditions. Microencapsulation is a promising technique solve address such problems. This study aimed encapsulate characterize the extracts produced by Penicillium chrysogenum R1 evaluate antifungal plant assay. capsules were prepared with chitosan (0.5 mg/mL) sodium alginate solution (2% w/v), 20% (v/v) cell‐free extract recovered from P. fermentation. synthesized 2.5% CaCl 2 at room temperature. characterized DLS SEM. To determine efficiency free encapsulated extract, they applied tomato plants infected Fusarium oxysporum . Once symptoms observed, severity incidence disease, as well morphological parameters evaluated. dry weight aerial root biomass, height, length, stem diameter, chlorophyll content, number leaflets. was chitosan/alginate size range around 300 nm. allowed efficiently control disease caused F. development plants. Therefore, effectively vascular wilt under greenhouse conditions, promoting growth.
