Citrus greening alert: Florida's citrus groves are at risk after Hurricane Milton

Strong winds and rain from Hurricane Milton have increased the risk of citrus canker spreading in Florida groves, according to Megan Dewdney, a UF/IFAS plant pathology professor.

Citrus canker is a bacterial disease that causes lesions on the leaves, stems, and fruit of citrus trees, leading to a reduction in fruit quality and yield.

Dewdney explained in a recent recovery webinar that strong winds create wounds on the tree canopy, leaving them vulnerable to infection.

While most fresh fruits on the market are currently immune to canker, grapefruits could be at risk. In the case of citrus trees protected under covers (CUPS), tears can allow canker to enter.

Megan Dewdney emphasized that stem lesions on young trees pose the most serious risk, as they can harbor bacteria for years, affecting future harvests.

She advised growers to conduct thorough scouting and consider treatments such as copper and immune stimulants.
