Queen Palm Tree diseases.
Ganoderma Rot, Fusarium Decline, Pink Rot, Bud Rot and Texas Phoenix Palm Decline are the most popular queen palm tree problems in Arizona.
The common signs of Ganoderma Rot are the drooping of the older leaves and yellowing of new growing fronds. The Queen Palm trunk sometimes collapses.

After pruning sick palm and getting rid of the sick palm roots, make sure you wash and clean your Saw as there is no chemical treatment for this.
When Queen Palm trees are infected by a Bud rot, the new palm fronds begin to develop black lesions and start to drop. This infection starts after a lot of rainfall when the bud gets spoilt by the cold. The older palm fronds will remain green but will begin to slowly die after a while. At this stage, the root system and the queen palm trees need to be destroyed to avoid the spread of this disease. The only remedy is to prevent the infection of Bud rot because there are no cures for the infection once it has been contacted. Overhead irrigation should also be reduced to help control the infection of Bud rot. Liquid Copper Fungicide has been found to be effective for the prevention of bud rot. This can be used on the uninfected palms to avoid the spread of bud rot to the entire garden.
There is no chemical treatment for Fusarium Decline, therefore, affected queen palm trees have to be uprooted and destroyed to avoid spread. The symptoms start with the oldest fronds turning yellow. As the first set of fronds turns brown, the set above it start turning yellow. This cycle is repeated till the whole queen palm tree becomes brown and dies off eventually.
Pink Rot affects weakened or stressed Queen Palm trees. The appearance of spots on the rachis and palm fronds is an indication of the pink rot infection.
