Abstract:
A study was conducted in plant pathology laboratory, SHUATS during 2019 to find out the in vitro efficacy of few botanicals (i.e. Neem oil, Eucalyptus oil, Castor oil), bio-agent (i.e. Trichoderma viride) in controlling of Fusarium udum causing wilt of Pigeonpea. The pathogen was isolated from the local fields of Pigeonpea and was identified by its morphological characters. Botanicals individually and in combination with the bio-agent were evaluated at 5% concentrations and to find the radial growth of the pathogen. The complete inhibition was obtained with Eucalyptus oil, Eucalyptus oil+ Trichoderma viride followed by Trichoderma viride, Neem oil+ Trichoderma viride and Castor oil+ Trichoderma viride. The present experiment was carried out by dual culture techniques and food poison techniques at same selected concentration.
