Abstract

Two fungal species Glomus mosseae and Glomus intraradices as well as Meloidogyne javanica nematode were used in order to evaluate the effects of arbuscular mycorrhizal fungi on control of different populations of root-knot nematode in tomato. A greenhouse test was established as factorial experiment based on completely randomized design with 8 treatments and 4 replicates followed by mycorrhizal fungi propagation as well as nematode identification. Different plant growth indices as well as nematode developmental parameters (gall numbers and egg mass on each plant, egg numbers in each egg mass and J2 numbers in soil) were estimated. Different nematode populations (5000, 10000 and 15000) were used in this experiment. Statistical analysis results showed that the mycorrhizal fungal species used in this study improved the growth of different plant parts and decreased nematode damages. Two fungal species did not have meaningful differences. Also, results showed that the mycorrhizal fungi have a high potential in effective control of root-knot nematode even in high populations.
