Studies on the life cycle of Meloidogyne incognita on papaya in presence of Fusarium solani

Lawal penetration in papaya roots was reduced in the presence of Fusarium solani. Further, only 66.3% penetrated lawae developed into females in Meloidogyne incognita alone in comparison to 42.7% where F. solani was present along with M. incognita. Fecundity was also reduced with an averge of 207 eggs per eggmass in roots infected with M. incognita and F. solani as compared to 356 eggs with M. incognita alone. Also, the percentage of male was high (7.3) in roots infected with M. incognita and F. solani. Presence of F. solani delayed the life cycle of the root-knot nematode by 9 days.
