Abstract:
Alternaria cucumerina (Ellis and Everh.) Elliott leaf blight is one of the threats limiting to bottle gourd (Lagenaria siceraria) cultivation in India. Considering the economic importance of the crop as well as destructive nature of the disease, present in vitro studies were undertaken to evaluate the efficacy of seven each systemic fungicides (each @ 500 and 1000 ppm) and non-systemic/combi-product fungicides (each @ 2000 ppm and 2500 ppm), to assess their potential against Alternaria cucumerina. Results indicated that among systemic fungicides mean mycelial growth inhibition recorded with the test systemic fungicides ranged from 63.89 to 100 per cent. However, the significantly highest and cent per cent (100%) inhibition was with Propiconazole 25% EC and Tebuconazole 25.9% EC, followed by Hexaconazole 5% SC (96.36%). Among non-systemic/combi-product fungicides highest mean mycelial growth inhibition was recorded with Carbendazim 25% + Mancozeb 50% WP (96.11%), followed by Mancozeb 75% WP (95.83%) and Chlorothalonil 75% WP (91.11%).
