Abstract:

Four fungal bioagents viz., Trichoderma viride, T. harzianum, Pochonia chlamydosporia and Purpureocillium lilacinum were screened for their efficacy against Meloidogyne incognita under in-vitro conditions through egg parasitism, egg hatch inhibition and second-stage juveniles mortality test. P. chlamydosporia showed highest egg parasitism. In respect of egg hatch inhibition and juvenile mortality, the culture filtrates of these fungal bioagents were tested and found to be effective in inhibition of egg hatch and mortality of juveniles of M. incognita at 25, 50, 75 and 100 percent concentrations. Among the bioagents, T. harzianum was showed highest egg hatch inhibition and juvenile mortality of M. incognita. Dose-response models were used in the larval mortality test to determine the concentration of culture filtrate required to kill 50 per cent of the juveniles. The culture filtrate of T. harzianum showed the highest activity with a LC50 value of 29.617 at 96 hrs of exposure.
