The potential of three biopesticides (Biofor-PF-2,Biozine-PTBandBiogreen-5)of Assam Agricultural University to provide protection against root penetration of infective juvenile of Meloidogyne incognita race 2 on King chilli was assessed in pots in net house condition. All the biopesticides were found to reduce the nematode penetration to various levels. Soil application with Biogreen-5 was the most effective of all the tested products in preventing juvenile penetration by up to 69.7 per cent, 6 days after inoculation with nematode compared to that in untreated check.
