Abstract

Fifteen strains of mushrooms and nine of yeasts were in vitro evaluated individually against the second stage juveniles (J2s) of Meloidogyne arenaria to evaluate their nematicidal effect. Each strain was tested either on solid medium in petri dishes or by using fungal filtrates in test tubes containing 100 J2s of M. arenaria. Results obtained after 24 h and 48 h of exposure period indicated that, four strains of mushroom (Stropharia regoseannulata, Coprinus comatus, Lentinula edodes and Volvurella volvacea) gave highly mortality percentage of the juveniles. However L edodes was the most effective strain, since it attained 100 % mortality percentage 24 h of exposure period, wheather on solid medium or using the fungal filtrate. Four strains of yeasts (S. cerevisiae QKS1, S. cerevisiae QOS1, S. cerevisiae OY and Rhodotorula rubra NY were considered as the most effective isolates where attained 100 % mortality percentage 24 h or 48 h of exposure period.
