Comparative pathogenicity of root-knot nematode Meloidogyne incognita on different pulse crops

An initial inoculum level of 100 juveniles of Meloidogyne incognita per plant caused significant reduction in growth characters of pulse crops and proved to be pathogenic. Reduction in growth characters varied from 1.13 to 69.06 per cent at different inoculum levels. Maximum dexrease was in lathyrus while minimum in french bean at 10,000 level. The multiplication rate of nematode was maximum at 10 inoculum level and minimum at the highest level. Gradual reduction in number of bacterial nodules was observed with the increase of inoculum levels in all the test crops maximum was at 10,000 level.
