sooby said:Bron, if you do want to treat with fungicides but spraying isn't practical, have you thought of trying a soil drench instead of spraying? A study found it was effective against daylily rust for quite a long period of time (with a specific systemic fungicide - I don't know if your product label there allows that use).
If you're seeing brown-black on the leaves, might it be the formation of telia (teliospores, the winter spores, as opposed to urediniospores, the summer spores)?
A drench might be a good thing to do with the plants in pots. Really soak them in it for a couple of hours. I am still continuing to pull the weeds and grasses out of my pots. They blow in and come up all the time. But after the amount of rain we've had, any ground drench would be washed away. Since my plants are in clay/shale subsoil, they are on slightly sloping ground. But, hang on, why would soaking the roots and ground be of benefit if the rust only lives in green parts?
Don't know about the dark brown stuff. But since there's no patrinia here, and if teliospores don't blow about like u'spores, it's better than producing u'spores. Can't imagine any living thing here thinking it was end of summer yet. Today was again like a sauna. Sweat dripping off when u bend down.
