The influence of inoculation of tomato plants with Glomus mosseae, a vesicular-arbuscular mycorrhizal fungus and phosphorus (P) nutrition on penetration, development, and reproduction of Meloidogyne incognita was studied in greenhouse. Results indicated that plants grown in high P soil had greater root weights, increased nematode penetration and egg production per plant, and increased colonization by mycorrhizal fungi, G. mosseae, compared with plants grown in low P level. VA mycorrhizae increased tomato fresh top and root weights, decreased nematode penetration and retarded reproduction. Mycorrhizal development and chlamydospore population produced on mycorrhizal-nematode infected roots were decreased, indicating the suppression of nematode on mycorrhizal plants. VA mycorrhizal fungus seemed to be more effective in reducing plant stress caused by nematodes, either the pre-infectional or post-infectional nematode-host relationship
