The bioefficacy of antagonist and botanical extract were tested in vitro against Fusarium oxysporum f. sp. ricini causing wilt of castor. Trichoderma harzianum (72.22%), T. viride (70.37%) and Pseudomonas fluorescens appeared potent antagonist against Fusarium oxysporum f. sp. ricini followed by T. faciculatum, T. longibrachyatum and Bacillus subtilis. Among the botanical, the extract of turmeric rhizome was effective in inhibiting mycelial growth 42.22 Per cent followed by 36.67 per cent inhibition by leaves extract of marigold. Pot culture experiment conducted at Department of Plant Pathology, College of Agriculture, Navsari. Antagonists and botanical extract which were found promising in in vitro study were tested in pot culture experiment. Result revealed that seed treatment with Trichoderma harzianum found superior in control of Fusarium oxysporum f. sp. ricini causing wilt of castor.
