Secondary metabolites released into the rhizosphere by Fusarium oxysporum and Fusarium spp. as underestimated component of nonspecific replant disease
Background and aims A study was performed to investigate the role of fungal metabolites released into the rhizosphere of replanted orchards as a potential biotic component of tree growth decline. Methods The phytotoxicity of the gamma ray-sterilized crude culture filtrates of sixteen fungal species...

Three out of the six species of Fusarium tested produced species-specific mycotoxins such as equisetin and enniatin B and D (<1 μg ml⁻¹ and <6 μg ml⁻¹, respectively) associated with root-tip necrosis, whereas fusaric acid (80–230 μg ml⁻¹) was associated with asymptomatic plant growth inhibition.
