Plumeria mosaic virus and spreading

[spike]

I have a plumeria cutting from home depot, but this year after it started leafing, I noticed there were a few leaves with these mottles and distortions. I'm fairly sure it's plumeria mosaic virus but it might also be due to the heat or powdery mildew. I doubt the nursery HD is buying from would take cuttings from viral trees, and other than some cuttings there are no large plumerias near me. I do have a fig tree with mosaic virus, and I've seen roses with it as well, but I doubt they can transmit to each other or to the plumeria. Any thoughts?

 Return it and get your money back..  Classic PMV.  Is transmissible to other Plumeria via sap.

As far as home depot ..wouldn't bet one cent on them actually taking the time to avoid accepting cuttings from infected trees. If accepting cuttings while dormant, no one would know which are infected or healthy. 

This is why you want to purchase Plumeria only from places that specialize in them and destroy any plants that show signs of infection rather than sell them. ( Upland Nursery, Florida Colors, Brad's B&B, B&B Exotics, Jungle Jack's ..etc < Though they have passed around infected stock in the past ) ..or start cuttings from a friend's healthy tree / start from seed.

Pretty sure the Plumeria Society of S. Cal has other smaller trustworthy growers nearby they'd recommend.. They also do pop up sales, and have the annual Plumeria Festival at Balboa in September ( Believe this year's event is still on ..Just checked.. Scheduled for the 3rd-4th in September ) where they sell dozens of plants..

thanks for the advice, but I doubt I still can return it. It's already grown and been repotted. I'll probably just trash it. I'm short on one gallon pots anyways, but is there a possibility of the soil spreading it?

Not 100% sure, but don't think so ..unless the virus contained in any sap that might drip into the soil below un- infected plants can penetrate the roots.. ( Good question though )

I know it has been stated  that if someone decided to keep an infected plant ( while it lives < usually only get weaker over time > ) you'd want to plant it well away from non - infected Plumeria specimens.

I did some research as well, apparently they can spread by soil and even pots, but I don't have any sensitive plants close by.

Also this,

Apparently it can cause symptoms in tomatoes but I don't know if it can spread naturally.

Saw this and a couple other research papers but they too kind of veered from PMV to general Mosaics as well..  Didn't realize smoke -from Tobacco - can also spread the virus.. Interesting.  Didn't see anything about insects being able to spread it ( At least in identifying an insect vector for PMV )  but possible one exists, just maybe not here in the states / part of the world..  Since all Plumeria species originate from this part of the world ( Mexico, Central and parts of S. America ..and the Caribbean ) would figure  PMV would have been id'ed in them ( ..and a potential insect carrier ) as species have been discovered / cultivated in  those areas.

Saw something else about Desert Rose ( Adenium ) being susceptible as well , Would bet Pachypodium could be as well.
