Abstract
The experiments on stunt nematode, Tylenohorhynchus vulgaris, affecting bajra crop were conducted to study (i) effect of temperature and pH on survival and virulence of T.vulgaris (ii) evaluation of bajra varieties / lines for locating source(s) of resistance to stunt nematodes and (iii) effect of stunt nematodes on seed germination, plant growth development and nematode reproduction on bajra cv, GHB 30 during 1989-90 and 1990-91. The salient findings are as under : ( i ) The per cent nematode survival was significantly more at 15 degree C temperature and 2 days exposure.Similarly maximum per cent nematode survival was recorded in pH 8 followed by pH 7 at 2 days exposure percent nematode survival gradually decreased with either decrease in pH from 7 or increase in pH from 8.
