Palm Tree Insects and Diseases
Bud Rot
This disease can be caused by various fungal pathogens, Phytophthora species and Thielaviopsis species, as well as by bacterial pathogens. While bud rot tends to occur after a tropical storm or periods of excessive rain, bacterial bud rot tends to occur after the bud has been damaged by cold weather. More »
Ganoderma Root
This disease is caused by the fungus, Ganoderma zonatu , which can infect many types of palm trees. The first symptom of infection is the withering and drooping of older fronds. More »
False Smut
False smut or Graphiola leaf spot is caused by Graphiola species. This disease is most common in areas of high humidity. Small, black, wart-like bodies are seen, often with yellow filaments protruding from the middle of the raised spots. More »
Leaf Spots
Leaf infections called “leafspots” are caused by a variety of fungi and some bacteria on many trees. Leaf spots can be circular to elongated, brown and possibly oily in appearance. The spots will vary in size and color depending on the plant, the organism involved and the stage of development. More »
Scale
If you found a lot of little circular, brown colored scales on your palm tree you are in trouble. It’s called “palm leaf scales”. You would never guess but palm leaf scales are actually a mature female small insect. They literally are just a small headless, legless bump and once the female has matured, it is unable to move from where it has planted itself. More »
Mealybugs
They belong to a family of unarmored scale insects found in moist, warm climates. Mealybug females feed on plant sap, normally in roots or other crevices. They attach themselves to the plant and secrete a powdery wax layer (therefore the name mealybug) used for protection while they suck the plant juices. The males on the other hand, are short-lived as they do not feed at all as adults and only live to fertilize the females. More »

I have the palm trees in my yard that have the 3 trees ( from one base) and big long branches (about 15 feet tall, sorry I don’t knowthe type) Sometimes the trees will produce short midget like branches like a quarter of the size that they should be. What causes this?
