Fusarium Wilt: A New Threat to Florida Lettuce Production

Germán V. Sandoya, Jesse J. Murray, Richard N. Raid, and Christian F. Miller

Fusarium wilt of lettuce is a disease caused by the fungus Fusarium oxysporum f.sp. lactucae. The disease is present in all lettuce production areas worldwide. Recently this disease has been identified in Florida in localized fields. This new 4-page publication of the UF/IFAS Horticultural Sciences Department presents information about the disease, symptoms, and control measures useful to lettuce growers in Florida. Following these recommendations may help to avoid the spread of this fungus in muck soils at the Everglades Agricultural Area (EAA), where 90% of the lettuce in Florida is planted.

It covers the insect's distribution, life cycle, physical characteristics, and economic significance, particularly its impact on ornamental plants like camellias and hollies. The article also discusses management strategies, including cultural, chemical, and biological controls, to mitigate the pest's impact. This document is part of the UF/IFAS Extension's Featured Creatures collection, aimed at both laypersons and academic audiences interested in entomology. First published: November 2001.
