Abstract

The presence of soil and root population of parasitic nematode viz., Helicotylenchus dihystera, Hoplolaimus seinhorsti, Meloidogyne incognita and Tylenchorynchus mashhoodi on Pterocarpus santalinus plantation was recored in soil. The population of H. dihystera and H. seinhorsti were found to be maximum in number i.e., 35.2 and 14.6/200 g soil, respectively during the month of October 2004 followed July 2004 and August 2004 due to receipt of heavy rainfall ranging from 45.0 to 233.3 mm during these months. The population of H. dihystera and H. seinhorsti was found to be 8.79/5g root during the month of October 2004.
