In vitro evaluation of chemical fungicides and bio agents against Colletotrichum gloeosporioides causing anthracnose disease in black pepper

Abstract

An experiment was conducted at Department of Plant Pathology, College of Agriculture, OUAT, Bhubaneswar and High Altitude Research Station, Pottangi during 2017-18 to evaluate effectiveness of various chemical fungicides and bio agents in inhibiting the mycelia growth of C. gloeosporioides under in vitro conditions causing anthracnose disease in Black pepper crop by poisoned food technique and dual culture method, respectively. Among the fungicides maximum inhibition was obtained with the combination fungicides carbendazim + mancozeb (0.1%) which gave 97.26% growth inhibition over control. Among different bio-control agents Trichoderma viridae gave maximum growth inhibition 88.97%.
