I found rust on my little Singapore this morning! I cut off most of the leaves and moved it off the deck away from the other plants. (Now I know what those little black spots on the leaves were). I will treat it but - will this type of rust spread to any of my daylilies - I have over 500 different cultivars. I have been so lucky so far that non of my dayliles have had rust when most of the people in my daylily club had it. Now what?
I found RUST this morning - help
Smdent, rust occurs a lot on the east coast and where there is a lot of humidity. Many people spray often with a fungicide, but sometimes, rust cannot be avoided. I've heard some people mention Bayleton for rust. It comes in granules and a spray. The spray is probably the most effective for immediate treatment.
Rust is also a natural phenomenon in plumie leaves and is a fungus which causes the leaves to defoliate when it is time to go dormant. Rust does spread by spores, but I believe it has to be carried by wind or rain or water, but I'm not sure about that. It is probably not a bad idea to move it away from your other plants. The rust would have caused the leaves to defoliate in time, and since you cut them off, you probably don't have to worry about the rust spreading.
It is probably getting cold/damp at night and probably time to bring your Singapore in at night. You can put it out during the day for direct sunlight. You can also start watering it less.
Clare,
Thank you - I do need all the help and any suggestions that you might have. The weather here is not cold yet, although the sun has not been out this week due to the storm off shore. I still have the air on and I just looked - it is 77 degrees outside right now. I live about 2 miles from the ocean so that buffers the cold until much later in the season. But the down side - I have to pay in the spring because it takes so long to warm up here. I should probably check all of the plants to make sure the spores did not travel to another plant. Hopefully I caught it quick enough.........
It may be all the humidity you have in the air then, which is normal. People in Florida have it the worst because of all the humidity there. Try spraying the remaining leaves and the stem with a fungicide. Safer makes a fungicide that is good, and they have that at Home Depot. Also, try to keep your Singapore in a drier place if you can. I have mine separated from the rest as well because I tend to spray my leaves a lot with water when I water, and since it is the most susceptible to Black Tip (also a fungus), I want to keep it drier than the others.
I had this problem a few weeks ago, see this thread. http://davesgarden.com/forums/t/536524/
I ordered the Bayleton from the site mentioned and it arrived at my home within 48 hours.
Good luck, it will be hot and muggy on the East Coast for a while yet.
Clare,
It has been super humid here for most of the summer. And - I did mist the plants which now I know did not help and I bet the rust was just lurking and I just helped it along.
Ardesia,
Thank you - I did go back and read what was written about the rust.
I wanted to spray all of the singapores this morning. I just purchased a product called Serenade a few weeks ago, and since I already had it I used that this morning. Has anyone tried Serenade yet? I think it is new.
Also - did anyone know if this rust is plant specific?
Smdent, I don't know if this particular rust is plant specific, but I doubt it is. I do know that roses get rust easily here. Here's a link about rust: http://www.plumeria101.com/problems/rust.html
