Evaluating The Efficacy of Bavistin Against Rhizoctonia sp., Helminthosporium sp., & Alternaria sp.

This study assesses the fungicidal efficacy of Bavistin (Carbendazim 50% WP) against three significant pathogens—Rhizoctonia sp., Helminthosporium sp., and Alternaria sp.—via the poison food method. Depending on the concentration, Bavistin inhibited fungal growth in varying degrees, with LD50 values determined as 68 ppm, 648 ppm, and 71 ppm respectively. These findings underscore the potential of Bavistin as a cost-effective, targeted solution to fungal infestations, offering economic and ecological benefits for Indian farmers, particularly in West Bengal. Optimizing dosage can address resistance and environmental impact concerns while enhancing crop yield.
