The field experiment was carried out in five years old Golsai variety of large cardamom (Amomum subulatum Roxb.) at Khandbari-4, Pangma of Sankhuwasabha district between February and April 2022 to evaluate the efficacy of bioagents and fungicides against Colletotrichum blight of large cardamom (A. subulatum). Two bioagents, three fungicides, and control/water were taken as treatments, and the experiment was established in a Randomized Complete Block Design (RCBD) with an area of 4×3 sqm in each experimental unit having 6 treatments with 4 replications. Treatment wise application of bioagents and fungicides was given by using a high-volume knapsack sprayer with the required concentration. Subsequent sprays were given at seven-day intervals. The result of the study showed that among the tested fungicides, TOPCARE (Azoxystrobin 50% WDG) and bioagent Trichoderma viride significantly reduced blight under field conditions. So, spraying of the fungicide TOPCARE (Azoxystrobin 50% WDG) and bioagent T. viride will be best for controlling Colletotrichum blight on large cardamom in the Sankhuwasabha district.
