Help, I just discovered tiny brown rust spots on several leaves of a Dwarf Singapore Pink. This plant is very important to me and I would prefer it not defoliate right now - or ever.
What's a good fungicide? I really have not used chemicals in years and when I checked the leftovers in the garage I found Fung-onil, the label says it is for lawns, it contains Bayleton. I also found Organicide which says it may be harmful to plants in the euphorbia family which was scary. I already cut off the leaves with spots but what else should I be doing?
Thanks.
What's good for rust?
good morning, I found this.

have you had excessive rains? sometimes that will cause it and after affected leaves are gone, so is problem.
Hi plummie mommy, thanks for answering. I am so upset, I thought I lost this little one last fall when it defoliated from rust. It has been so healthy this summer. We have not had excessive rains recently but we have had humidity in the 85% - to 90% range pretty steadily.
As you can see it is not a huge problem - yet. I just cut off 5 leaves that had these tiny spots. They do have the familiar orange spot on the reverse side of the leave.
This was the plant before I had to amputate those leaves. It had several open flowers already but a large bird pooped on the poor plummie last night and I had to give it a bath and remove some of the more damaged flowers this morning. That is when I noticed the spots on the leaves.
wow, it's really grown. Personally, I don't think rust is the end of the world but better plumie parents will likely disagree. I'm also not too concerned about black spot in roses, or cannas devestated by leaf borers, so.......
LOL, Obviously, since it defoliated before, rust is not fatal but it was going along so nicely..... :-(
When you live in the sticky SE you get used to a lot of things that others would rather not deal with. BS is a way of life around here and, IMO, some roses handle it better than others. If they choose to die off from it I let them go to plant heaven. I used to grow a canna that always looked really ratty from the borers. Now I grow species cannas that never have any problems - It makes lilfe so much easier.
The plummie is still in an 8" pot, do you think I should move it up?
I have an appt. to get my hair cut this afternoon, I'll look for the fungicide when I am in town.
you can move it to a larger pot next yr, unless you're itching to sweat in the heat doing this or you have a nifty pot that you simply must put to good use now.
I didn't know that about species vs hybrid cannas. I have one that may be indica or coccinea, and just a few minutes ago I was noticing how unblemished it is, as opposed to my Pink Sunburst, which is a pathetic sight right now. Thank goodness it is hidden by a bunch of caladiums.
I don't have a larger pot, but I thought looking for one would be fun. :-)
This morning it was only 80 which was so welcome after the heat these past weeks. I planted 4 plants in my butterfly garden, it was so nice to be outside.
