Agrobacterium tumefaciens stimulated and Fusarium oxysporum f. sp. lycopersici inhibited development and reproduction of Meloidogyne incognita when applied to the opposite split root of tomato, Lycopersicon esculentum cv. Tropic, plants. The lowest rate of nematode reproduction occurred after 2,000 juveniles were applied and the fungus was present in the opposite split root. The effects of all three pathogens alone on the growth of roots and shoots of tomato plants were evident, but M. incognita had a greater effect alone than did either of the other pathogens. The length of split roots was reduced by the infection of M. incognita and A. tumefaciens or F. oxysporum f. sp. lycopersici. The number of gaits induced by nematodes on roots was higher where the bacterium was applied and lower where the fungus was applied to the opposite split root.
