Bud Rot Phytophthora palmivora

Bud rot is caused by a fungus which causes the heart fronds of a palm tree to wilt and die. Tree death can occur soon afterward. California and Mexican palms are the most vulnerable. Summer is the worst season for bud rot. Chemicals can be effective in the early stages of the disease. Consult a specialist and follow directions carefully. In all cases where fungal infection is a threat, it is important to prevent the careless spread of spores. Make sure gardening tools are kept clean at all times. Sterilize between finishing work on one tree and starting work on the next.
