Evaluation of compatibility of various chemical fungicides with Cordyceps militaris (L.)Link

Cordyceps militaris is a well-known entomopathogen currently being explored for its
mycoparasitic ability against plant pathogens. The compatibility of C. militaris was tested
against various group of fungicides at systemic (0.075%, 0.050%, 0.100% and 0.150%) and
non-systemic doses (0.25%, 0.50%, 0.75% and 1.00%) to assess whether they can
effectively coexist or be used in combination with fungicide treatments in integrated disease
management scheme. It was observed that C. militaris showed highest compatibility with
copper oxychloride with the least mycelial growth inhibition (15.34±0.53%) even at the
highest concentration (1.00%). Among systemic fungicides, azoxystrobin and metalaxyl
were found to be compatible with C. miltaris only at lower concentrations upto 0.25 per cent
and showed a 100 per cent inhibition of mycelial growth at concentration more than 0.25 per
cent whereas carbendazim was incompatible at all the tested concentrations.
