When to act
Every six months, walk every row and look for palms with several unopened spears, drooping yellow fronds or brackets at the trunk base. Mark each sick palm and its neighbors. Fell, dig out and destroy palms that have brackets or have fallen.
Before you spray
No fungicide saves a sick palm. Dig out and chop infected stumps and roots at replanting, and drain and feed the palms well.
How to prevent it
- At replanting, dig out the old stumps and their root masses, chop them small and let them dry, instead of leaving them to rot in the rows.
- Do not plant new palms where an infected palm or stump stood without clearing its roots first.
- Heap soil around the base of a lightly infected palm. It keeps the palm standing and yielding longer.
- Keep the field drained and the palms well fed, with enough potassium, so they hold out longer.
- Clear trunk debris and dead palms quickly, since brackets on them shed spores.
Natural enemies and biological help
- Trichoderma and mycorrhiza added in the nursery and planting hole help young palms resist. They do not cure a sick palm.
