Plumeria Diseases And Their Treatment: The Complete Guide - Garden Sigma (2024)

Plumeria are prone to various fungal diseases such as rust fungus, white fungus, black tip fungus, black rot, and viruses that can cause color break. These diseases can cause severe damage to plumeria plants if left untreated, so it is vital to be aware of the signs and take appropriate action to prevent and control these diseases.

The Plumeria Fungus

Plumeria fungus is caused by two plumeria-specific fungi,Coleosporium dominguenseandColeosporium plumeriae. This is the most often found of plumeria diseases. This fungus is most common in humid and wet climates and can quickly defoliate an entire tree. Plumeria fungus symptoms include red-orange bumps on the top of the leaves and powdery spore masses on the underside.

Plumeria Fungus Prevention

To prevent plumeria fungus, we can take several steps:

1. Cleaning the growing area and removing infected leaves.
