Abstract:

A field study was undertaken at central research farm of Sher-e-Bangla Agricultural University's (SAU), Dhaka during November 2022 to April 2023.The experiment was configurated in RCBD design to assess the antifungal potentiality of micronutrients (Zinc, Boron, Magnesium), botanicals (Neem, Vet, Nishinda leaves extract) and chemical fungicides (Dithane M-45, Rovral, Ridomil Gold) against purple blotch complex pathogens of onion. Data were recorded on percent disease incidence, percent disease index and different morphological parameters. From the results of the study, it was revealed that among the micronutrients and botanicals, boron and neem gave the satisfactory results. But plots treated with fungicides, Ridomil Gold gave superior performance by lowering percent disease incidence (38.88%) and percent disease index (36%) with higher yield and yield attributes. However, from the findings, it can be concluded that although the chemical fungicides showed the best performance, but in combination of micronutrients and botanicals may be used as bio-rational management.
