Control of Meloidogyne incognita and Rotylenchulus reniformis singly and concomitantly on pigeonpea with Paecilomyces lilacinus

The root-knot nematode, Meloidogyne incognita caused greater reduction in plant growth, chlorophyll content water absorption capacity of roots, root nodulation and bulk density of woody stem of pigeonpea than the reniform nematode, Rotylenchulus reniformis. These nemntodes inhibited each other development in concomitant infections. However, both the nematodes together caused more damage to the plants than either of them singly, and it was less than the sum total of the damage caused by them individually. The nematodes were found to be less damaging in the presence of Paecilomyces lilacinus The multiplication rate of nematodes was less in presence of P. lilacinus compared to the absence of P. lilacinus.
