Wilt caused by Fusarium oxysporum f. sp. ricini poses a major problem in all the castor growing areas of the country. Since the soil borne disease can be effectively controlled by biocontrol agents, the present study was conducted to know the antagonistic activity of different bioagents in vitro at department of Plant Pathology, College of Agriculture, UAS, GKVK, Bengaluru during 2019-20. Eight fungal and eight bacterial bio-agents were evaluated using dual culture method. Th14 strain of Trichoderma harzianum exhibited highest (80.47%) inhibition of mycelial growth of F. oxysporum f. sp. ricini while the remaining strains of both T. harzianum and T. viride were able to control the pathogen at least by 72 per cent under in vitro conditions. In case of bacterial antagonists Bacillus velezensis (P42) showed a good inhibition of 58.89 per cent over the rest.
