Talc based bioformulations namely Biofor PF-2, Bioveer, Biomonas and Biozin PTB were evaluated against damping off disease of tomato. Application of these bioformulations as seed treatment and in nursery bed treatment before sowing significantly reduced the pre- and post-emergence damping off of tomato. Among all the bioformulations tested, Biozin PTB was found most effective in reducing maximum (76.68 and 70.76 per cent) reduction of pre- and post-emergence damping off of tomato. Besides reducing the pre- and post-emergence damping off, Biozin PTB also caused maximum increase of root length, shoot length and biomass production of tomato seedlings.
