|What can I do to get rid of the rust fungus on the underside of the leaves on my plumeria? I live in So FL. TY|
|Signs of plumeria rust (Coleosporium plumeria Pat.) consists of orange blistering or powder on the undersides of the leaves, and it develops after prolonged wet
periods. The leaves may fall if the rust is severe. While fungicides specific
for rust control are effective, they are not normally used, because the disease is rarely severe enough to damage the plant. However, if you want to use a fungicide, use Green Light Fung Away or similar fungicide for rust. Be sure to follow label directions.
