The density and frequency of occurrence of Meloidogyne and Rhizoctonia, associated with tomato in AndhraÂ Pradesh, were found to be influenced by various ecological factors, viz. soil type, cultivars, previous crop grownÂ and stage of crop growth. The population of Meloidogyne was maximum in the loamy soil, cultivar Tulasi whenÂ the previous crop was water melon and at the flowering stage. Minimum population was observed in clay loamÂ soils, cultivar Sridevi, when previous crops were onion, maize, paddy or when field kept fallow and at vegetativeÂ stage. Similarly, the maximum population of Rhizoctonia was observed in sandy loam soil, in US618 cultivar,Â when previous crop was potato and at flowering stage.
