Lifecycle
Spreads through conidiospores that move throughout crown whorls until all leafstalks are infected. Once infection is established, it continues throughout the year. Cool, foggy weather conditions favor disease development and spread.

Remove and destroy infected palm material immediately
Improve air circulation around palm crowns
Avoid overhead irrigation that promotes moisture retention
Professional diagnosis essential for proper identification
