Abstract:
Eggplant (Solanum melongena L.) is a vital vegetable crop in tropical and subtropical regions, with South Asia contributing nearly 50 percent of the global cultivation. However, the crop faces a significant threat from Phomopsis blight, caused by Phomopsis vexans, which can result in yield losses of up to 70 percent. In this study, we explored biocontrol agents and plant extracts as potential strategies to manage Phomopsis blight in eggplants. Our results revealed promising outcomes in combatting this disease. Among the biocontrol agents evaluated, Trichoderma viride stood out, demonstrating a remarkable 70.57 percent inhibition of Phomopsis vexans growth. Furthermore, neem leaf extract exhibited significant antifungal activity, with a 39.61 percent reduction in mycelial growth. These findings highlight the effectiveness of these natural alternatives in suppressing Phomopsis blight. Biological control, particularly through Trichoderma species, presents an eco-friendly and sustainable approach, offering potential for reducing the reliance on chemical fungicides. Moreover, neem leaf extract's antimicrobial properties against the pathogen underscore its potential for integrated disease management.
