Abstract
The current study tests the efficacy of various fungicides for controlling the Alternaria leaf spot disease of Asalio. The field experiment was conducted during Rabi-Summer 2018-19, 2019-20, 2020-21 and 2021-22 for management of Alternaria leaf spot of Asalio through fungicides. The results indicated that the treatment T5 i.e. seed treatment with combi fungicide, Carbendazim 12 % + Mancozeb 63 % WP @ 0.30 % + three foliar sprays with Tebuconazole 25.9 % EC @ 0.1 % recorded significantly lowest PDI (27.89%) of Alternaria leaf spot with 58.39 % reduction in disease over control, moreover the same treatment also recorded significantly highest seed yield (20.89) q/ha and highest B: C ratio (2.43) as compared to rest of the treatments.
