Fusarium wilt of castor
-
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.

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.

Castor (Ricinus communis L.) experienced serious declines in yield caused by wilt pathogen Fusarium oxysporum f.sp. ricini. To control the wilt pathogen, commonly fungicides are used, which cause undesirable toxic effect on the environment. To minimize the pollution impact, there is an urgent need to develop alternative ecofriendly strategies. Therefore, to fill these knowledge gaps and to investigate potential botanical's efficacy on the wilt pathogen F. oxysporum f.sp. ricini, an in vitro bioassay was conducted. Twentysix botanicals were extracted at two different concentrations viz.
