Incidence of Phoma leaf spot disease of large cardamom (Amomum subulatum Roxb.) and in vitro evaluation of fungicides against the pathogen

摘要

Surveys conducted in 17 locations in North East India indicated that the incidence of Phoma leaf spot disease of large cardamom (Amomum subulatum.) caused by P. hedericola ranged from 5% to 15%. Six fungicides were evaluated in vitro against the pathogen and carbendazim 50WP was significantly effective at all concentrations (0.05% - 0.15%) tested followed by carbendazim + mancozeb 75WP (0.1% - 0.4%).
