Management of damping-off of tomato caused by Pythium aphanidermatum (Edson) Fitz. through biocontrol agents, organic amendments and soil solarization

S. Usha Rani, G. Satheesh

Abstract

Among six biocontrol agents tested Trichoderma viride exhibited maximum inhibition (71.85%) of P. aphanidermatum. Soil solarization for different duration on seed germination and growth parameters revealed that TPE 0.05 mm for 40 days recorded 96% (seed germination) and a vigour index of 2208.0. Among various treatment combinations, thiram recorded 12.6 and 8.0% followed by ST+SA (T. viride) which recorded 13.6 and 9.0 pre and post emergence damping-off, respectively.
