Abstract

The present investigation reveals laboratory based studies on the effect of different soil temperature on the population build up of Pratylenchus penetrans under tea plantations in sandy-clay and sandyloam soil. An initial population of 100 P. penetrans showed maximum number (1912) at 25°C in sandy-clay whereas in sandy loam soil the number was 1692 at 30°C on termination of the experiment, after three months. The lowest population of P. penetrans (129) was observed in sandyclay at 35°C and (250) in sandy-loam at 35°C. The findings of the present investigation have been compared with the results of earlier workers.
