A fungal disease called Phytophthora can cause root or crown rot. This fungus thrives in wet, poorly drained soil. Phytophthora can be treated by moving the palm to new soil, cutting out the rot and treating the palm with a fungicide for use on cycads (plants with a stout woody trunk and a crown of large leaves).
Appearing as tiny white spots on the plant, the fungal juice is fed on by scale and mealybugs. To get rid of these pests, their protective layer should be dissolved. Insecticidal soaps and mild alcohol solutions are effective treatments, but they may take long to work.
