Phytophthora foot rot (Phytophthora capsici) of black pepper (Piper nigrum L.) is most devastating disease in Uttara Kannada district of Karnataka which is situated in Central Western Ghats. The antagonistic organisms viz., Trichoderma viride, T. harzianum, Laetiseria arvalis, and Bacillus subtilis were tested against P.capsici in pot culture by adding infected material to healthy vine. Among the four bioagents tried, Trichoderam viride and T. harzianum were effective in reducing the incidence of the disease as compared to Laetiseria arvalis, and Bacillus subtilis. The disease incidence was maximum in untreated vines.

Abstract


Phytophthora foot rot (Phytophthora capsici) of black pepper (Piper nigrum L.) is most devastating disease in Uttara Kannada district of Karnataka which is situated in Central Western Ghats. The antagonistic organisms viz., Trichoderma viride, T. harzianum, Laetiseria arvalis, and Bacillus subtilis were tested against P.capsici in pot culture by adding infected material to healthy vine. Among the four bioagents tried, Trichoderam viride and T. harzianum were effective in reducing the incidence of the disease as compared to Laetiseria arvalis, and Bacillus subtilis. The disease incidence was maximum in untreated vines.
