Possible simultaneous/integrated biological control of soil pests by mixed application of entomopathogenic and fungivorous nematodes

Massive application of fungivorous nematode, Aphelenchus avenae, with 2 times 10 to the power of 5 per 500 ml of autoclaved soil in summer at 26-33 degree celsius and 5 times 10 to the power of 5 nematodes in autumn at 18-23 degree celsius effectively suppressed the preemergence damping-off of cucum...
