| Leaf Spots and Leaf Blights |
|---|
* Leaf spots and leaf blights are cause by numerous fungal pathogens, but the symptoms they cause are relatively similar for all of them.
* All palms should be considered hosts for leaf spots and leaf blights, especially in the juvenile stage.
* Leaf spots initially start as small, water-soaked lesions that turn various shades of yellow, gray, reddish-brown, or black. These lesions may be surrounded by a halo or ring of tissue that is a different color.
* Leaf spots can increase in number or size such that large portions of a leaf blade are diseased.
* Sanitation and water management are critical for leaf spot and blight disease management. Injury prevention and good nutrition are part of the overall care strategy.
* Fungicides may be useful as part of an integrated management program, though should never be the sole componenet in treatment.
