The bioefficacy of different bioagents viz., Paecilomyces lilacinus (2x106 cfu/g), Pseudomonas fluorescens (1x109 cfu/g), Trichoderma viride (2x106 cfu/g), Phule Trichoderma plus (2x106 cfu/g) and Pochonia chlamydosporium (2x106 cfu/g) against second stage juveniles of ischolar_main-knot nematode infesting bottle gourd crop was studied under laboratory conditions. In this bioassay Paecilomyces lilacinus fungus caused higher rate of juvenile mortality at 1.00 per cent concentration was found to be promising in laboratory bioassay studies and recorded 80.00 per cent mortality of second stage juveniles of ischolar_main-knot nematode. This was followed by 76.67 per cent mortality of second stage juveniles of ischolar_main-knot nematode by Pseudomonas fluorescens at 1.00 per cent concentration after 72 hrs treatment of respective bioagents. The fungi Phule Trichoderma plus, Trichoderma viride recorded 70.00, 66.67 per cent juvenile mortality, while as in case of fungi Pochonia chlamydosporium 53.33 per cent juvenile mortality was observed after 72 hrs treatment of respective bioagents at 1.00 per cent concentrations.

The bioefficacy of different bioagents viz., Paecilomyces lilacinus (2x106 cfu/g), Pseudomonas fluorescens (1x109 cfu/g), Trichoderma viride (2x106 cfu/g), Phule Trichoderma plus (2x106 cfu/g) and Pochonia chlamydosporium (2x106 cfu/g) against second stage juveniles of ischolar_main-knot nematode infesting bottle gourd crop was studied under laboratory conditions. In this bioassay Paecilomyces lilacinus fungus caused higher rate of juvenile mortality at 1.00 per cent concentration was found to be promising in laboratory bioassay studies and recorded 80.00 per cent mortality of second stage juveniles of ischolar_main-knot nematode. This was followed by 76.67 per cent mortality of second stage juveniles of ischolar_main-knot nematode by Pseudomonas fluorescens at 1.00 per cent concentration after 72 hrs treatment of respective bioagents. The fungi Phule Trichoderma plus, Trichoderma viride recorded 70.00, 66.67 per cent juvenile mortality, while as in case of fungi Pochonia chlamydosporium 53.33 per cent juvenile mortality was observed after 72 hrs treatment of respective bioagents at 1.00 per cent concentrations.
