Abstract

To evaluate the effect of Glomus mosseae and Trichoderma virens, on root knot nematode (Meloidogyne spp.) in tomato plants, a greenhouse experiment was performed in a completely randomized design with seven treatments in four replicates. T. virens was isolated from the wheat fields of Fars province and cultured on PDA medium. G. mosseae provided from the Department of Horticulture, University of Valiasr, Rafsanjan. Pure culture of G. mosseae, was established in pot culture. The individual and mixed effect of both fungi was assessed. The results indicated the positive effect of the mixture of the both fungi (T. virens + G. mosseae) on tomato growth as well as the nematode reproduction factors. In this treatment, the number of galls/g of root, compare to 7.28 in control reduced to 0.72, the number of egg masses reduced from 2.76 to 0.39, number of J2s from 3553.5 to 2471.25 and reproduction factor reduced from 2.13 to 1.48. The growth-related factors in tomato plants were improved in treatments G. mosseae and T. virens + G. mosseae, as compare to both inoculated with M. javanica and uninoculated controls.
