Postharvest suppression of potato dry rot (Fusarium sambucinum) in prenuclear minitubers by arbuscular mycorrhizal fungal inoculum.

A commercial peat-based medium containing Glomus intraradix [Glomus intraradices] was studied to determine if it could influence postharvest progression of tuber dry rot in prenuclear potato minitubers. Minitubers developed significantly less tuber dry rot (20-90% reduction) in the medium with G. intraradices when inoculated with F. sambucinum [Gibberella pulicaris] compared with those grown without the fungus. Disease suppression also occurred in a high-input commercial greenhouse, despite only trace levels only of arbuscular mycorrhizal colonization of the parent plants, and with no evidence of enhanced plant P nutrition or differences in minituber mineral content. It is suggested that the fungal inoculum has potential for use in suppression of tuber dry rot of potato.
