Yield loss and management of Oedocephalum cultivation of Calocybe indica

Oedocephalum made its appearance as irregular, light silver gray patches on the substrate. Out of the four inoculum levels tried, maximum (41.0%) yield loss was recorded with 2.0 g inoculum load. Among fungicides, bavistin and sporgon proved to be the most toxic at all the concentrations tried and gave 100% mycelial inhibition. Neemol was the most effective plant product at both the concentrations tried as it gave 90 and 93% reduction in the mycelial growth of Oedocephalum at 2% concentration when it was added pre and post sterilization of the substrate, respectively. Two sprays of sporgon were most effective against Oedocephalum which gave 750 g yield/5 kg wet substrate.
