Soil mycoflora in tomato fields

Density and species richness of fungal communities in soils ofFusarium infested and non-infested tomato-growing localities were studied by comparison of rhizoplanes, rhizospheres, and root-free soils. The rhizosphere soils harbored the highest counts of fungi, followed by root-free soil and rhizoplanes in both localities. Species richness was high in the rhizosphere and root-free soil but distinctly low in the rhizoplane. The population density of the zhizosphere and the rhizoplane showed a significant difference between infested and non-infested localities.
