Fusarium
Fusarium yellows of sugarbeet was first identified in the Red River Valley in 1996 near Moorhead, Minnesota. Fusarium yellows is caused by fungus, fusarium oxysporum f. sp. betae, although other fusarium species can be involved as secondary invaders. The disease causes significant reduction in root yield and recoverable sucrose. In storage, quality of infected roots may deteriorate more rapidly than in non-infected roots.
