An greenhouse experiment was performed to assess the relationship between Fusarium spore densities in the soil and infection rate of black-pepper seedlings. Mata soil (a forest soil of the Amazon) were inoculated with spore suspension increasing concentration from 2.7×102 to 5.4×105 spores 1g soil. There was a positive correlation between the concentration of spores in soil and infection rates of the seedlings.
