Title: Interaction of VA Mycorrhizal Fungi and Root-Knot Nematode on Tomato Plants: Effects of Nemacur, Phosphorus and Infection Time
Author: Mirghani, Ayman M. O.; Elsheikh, Elsiddig A.E.
Abstract: Pot investigations were designed to study the effect of inoculation time, phosphorus (P) and nemacur on the interaction between V AM fungi, Glomus sp, and root-knot nematode, Meloidogyne incognita, on tomato (Lycopersicon esculentum) growth. The results indicated that addition of P or Glomus sp significantly increased the shoot and The addition of P, nemacur or Glomus sp significantly root dry weight and P content. decreased the gall number in plants infected with M. incognita. Addition of P significantly decreased the mycorrhizal infection percentage, whereas, the addition of nemacur did not affect it. Shoot and root dry weight and P content were significantly increased, whereas, the gall number significantly decreased, when the mycorrhizal The results indicated that tomato growth infection preceded the nematode infection. could be improved by the addition of mycorrhiza, which could also be used as a control for root-knot nematodes.
