Good Morning and Happy Australia Day. This is my first post here, so hello Everyone.
I have three evergreen frangipanis in my garden in inner Brisbane. Two weeks ago they showed no sign of rust at all, but now they have patches of orange rust on the underside of the leaves. The top of the leaves have small yellowed patches. It tends to affect the older leaves first, causing them to wilt and drop much earlier than they should. I tried mancozeb last year (the first year after I planted them) but it didn't get on top of the problem. Has anyone found something that works for this rust? Thanks! |

Hi,
I live in Brsbane and also had this problem.I too found that the mancozeb did nothing. I would be intersted in other gardeners' responses. The only thing I can say is to make sure that you collect all fallen leaves and put them in a plastic bag in the rubbish. |

Hello 'verandah' ,
Hate to be the bearer of bad news but about 12 years ago the problem arrived from Florida and it is a tough nut to crack. No matter how good your own housekeeping is, the rust is airborne and it can travel quite a distance on the wind. I think it is the same rust you get on cannas. If you have cannas the rust will live on those over winter ready to invade again once the summer rains arrive. I have tried a number of different sprays without success.
At all times you must dispose of all leaves (not in mulch)and be sure to cut your cannas to the ground in winter. I applied a fresh layer of sugar cane mulch over some areas of my cannas this year and those cannas did not get the rust so the rust may also live in/on the soil during winter. I was told to spray soil after you have cut down foliage with a solution of bleach but I was going to try that this winter. If anyone out there has a proven remedy to this it would be fantastic because it does ruin the look of an otherwise beautiful tree. Don |

Rust is an awful problem. I have always been very careful of the trees I get cuttings from but I slipped when I bought a Dwarf Darwin Pink from Big W and didn't notice it till a few days after I took it home.
I make sure that I pull all the leaves off and bag and burn them.
There is a site called Plumeria 101 and they have some information on this.
Sorry haven't learnt how to link yet.

| Hello Marion, I checked out the Plumeria 101 site and they list a product called PLANTVAX 75WP as a sure cure for this problem. Well I have paid the $85 for 500g of this stuff and it did nothing when sprayed according to the directions. I was thinking of doubling the dose next time to see if the result is any different. I will keep the site posted if it works. Don |

| Hmm. Thanks for the commiserations and advice. All my neighbouring gardens have big old frangipanis, so it's going to be a toughie. I'll try some heavy mulching. Thanks Don. I can't find out with a quick web search much about the life cycle of this rust, so don't know whether it lives in soil too, or has other alternate hosts that it NEEDS for its survival eg cannas. I'll soldier on and try everything. |

| Hi I dont have any rust here YET but when I live in Townsville all my shrubs got it, I just pulled the leaves of and binned them, it seems to come late in the season up there. Here in Brissie I have lots of Canna's growing about 10 ft away and no problems as yet but just to be on the safe side I will pull them out. My shrubs are only 2-4 years old and at the most 6ft high. I dont know if this will help but have a read of the link below. MM. |

| Thanks MM, there's another good link below too. Nothing that says definitively that it lives in soil though. |

| Spraying with copper oxychloride will help in the prevention ,needs to be done regularly in the summer. |

| I think it is just a case of living with the rust. The plant still puts on new growth and flowers well. So long as I collect the fallen leaves, I think that is all I can do |

I just noticed that all my four frangipani plants have the frangipani rust :((( its in early stages as i noticed only small areas of the leaves affected.
Checked on google for solutions and it said that MANCOZEB fungicide should help..i will try it out..i really hope i find something as i got these from bunnings and they are the dwarf breed with gorgeous coloured flowers...
HAPPY AUSTRALIA DAY TO YOU ALL!! |

| I have used the rust rid mentioned above.. Worked really well..I had about 3 of my seedlings have brown spots on the leaves but not rust... Non of my mature plants had any rust on them at all this year and I have over 40. Last year was shocking with most of them having rust... Recommend RUST RID. |
