Influence of Glomus fasciculatum on Meloidogyne incognita Infected Tomato

Pre-colonization of mycorrhizal fungi (200 chlamydospores) as a symbiont in tomato cultivar and nematode interaction system enhanced plant growth by reducing the nematode parasitism. The level of nematode parasitism affected by mycorrhizal fungi was directly correlated with the colonization % of the root system. A maximum of 81.2% reduction in gall number was observed at 6^th week, when colonization percentage was 71. At this stage, root contained all types of fungal structures. The root colonization was found to be directly correlated with period of infection and density of chlamydospores inoculated. The colonization of root system remained unaffected when Meloidogyne incognita was present.
