Answer: Dear Rosanna,

You can use a Yates product called Rose Shield or a ready to use product called Fungus Gun. Both these products contain a systemic fungicide that will control rust. You will need to spray thoroughly underneath the frangipani leaves to contact the rust spores. Repeat the spray in 2 weeks time. Also pick up any diseased leaves that have fallen on the ground. The tree will shortly be shedding its leaves for winter. Next summer check your tree on a regular basis for this problem and spray before the disease takes hold.
