Effect of Plant Age at Transplanting on Disease Severity of Meloidogyne Incognita

The effect of plant age at transplanting on the severity of Meloidogyne incognita infection on resistant and susceptible cultivars of tomatoes were infested at age 5,3 and 1 week witheggs concentration of 15,000 per plant. There was a decline in final nematode population (Pf) with increase age at transplanting for both cultivars. Severity of infection in susceptible cultivar was pronounced in 2 weeks old transplant. General growth and development was significant lower in younger seedlings regardless of the fact that the resistant cultivar showed no disease symptoms.
