Studies on compatibility of egg parasitic fungi with other biocontrol agents and carbofuranunder in vitro
M Muthulakshmi, B Anita and S Subramanian
The egg parasitic fungi viz., Pochoniachlamydosporia and E. aranearum were studied for their compatibility with other biocontrol agents viz., Pseudomonas fluorescens, Bacillus subtilis,Trichoderma viride, Paecilomyces lilacinus and carbofuranunder in vitro. The experiments were incubated at 28 ± 2 oC, the observations were recorded in 5 and 10 days intervals. The growth of T. viride and P. lilacinus was rapid when compared to P. chlamydosporia and E.aranearum isolates. Since both these fungi were compatible with each other, zone of inhibition was not observed. There was no inhibition in the growth of the fungus or bacterium in the medium. Growth of the fungal isolates was faster than P. fluorescens and Bacillus subtilis. Spore production in both the fungal isolate was not suppressed by P. fluorescens and B. subtilis. Carbofuran did not suppress the growth the fungus. The egg parasitic fungi, P. chlamydosporia and E. arenearum was found compatible with other biocontrol agents and carbofuran in vitro.
