Antimicrobial and antifungal activity of Aegle marmelos L. water extract for managing Solanum lycopersicum L. plant diseases 

 - p 677-682 
<br/><br/> The present study targets the management of tomato<br/>plant diseases caused by bacterial and fungal pathogens through natural pesticides. The antimicrobial and<br/>antifungal activities of water extract from Aegle marmelos L. were assessed in vitro at various concentrations. For antimicrobial activity, the zone of inhibition<br/>(ZOI) was measured, revealing that at 100 mg/ml concentration, the plant extract exhibited a ZOI greater<br/>than 15 mm for bacterial strains, Xanthomonas spp.<br/>and Clavibacter michiganensis ssp. michiganensis. For<br/>antifungal activity, the percentage of inhibition was<br/>measured at different concentrations of the plant<br/>extract. At the highest concentration of 10 mg/ml,<br/>complete inhibition (100%) was observed for Botrytis<br/>cinerea, whereas 77.5% inhibition was observed for<br/>Phytophthora nicotianae var. parasitica. Subsequently,<br/>in vivo experiments were conducted where the plant<br/>extract was used as a natural pesticide. Compared to<br/>the control, the treated plots demonstrated a significantly higher survival rate. These findings suggest that<br/>A. marmelos L. water extract can serve as an effective<br/>natural pesticide, providing a viable alternative to<br/>chemical pesticides in tomato disease management.
