Fusarium crown rot seed fungicides: independent field evaluation, 2018–2020

Abstract

Key findings • Current fungicide seed treatments registered for the suppression of Fusarium crown rot (FCR) inconsistently reduce the extent of yield loss from this disease. • Victrato® had consistent and stronger activity than other seed treatments on limiting yield loss from FCR. • Under high FCR infection levels significant yield loss may still occur with the use of Victrato® in drier seasons. • Fungicide seed treatments, including Victrato®, should not be considered standalone control options for FCR but can be used as an additional tool within existing integrated disease management strategies for FCR.
