The experiment was conducted in plant pathology laboratory of Nepal polytechnic institute for studying in invitro efficacy of Trichoderma isolates on Sclerotinia sclerotiorum causing white mold of kidney bean, Bharatpur, Chitwan, Nepal by dual culture technique. The experiment was carried out in completely randomized design (CRD) with four replications. The Trichoderma isolates namely Kapilvastu Isolate, Kavre Isolate, Salyan Isolate, Lalitpur Isolate and Taplejung Isolate were used in the experiment. The mycelium growth was measured at 2DAI, 4DAI, 6DAI, 8DAI and 10DAI. Also the number of Sclerotia, days to Sclerotia formed and width of the browning area at the region of interception were measured in 10DAI. All the Trichoderma isolates shows significant effect on the mycelium growth and number of Sclerotia formed. Among all the Trichoderma isolates, Lalitpur Isolate shows good result with 69.33% inhibition in the mycelium growth and number of Sclerotia (9.6~10) formed.
