Q.African violet deseases
I had an african violet shipped. It was a graft from a leaf and very small. The big leaf has turned grey and I cut half of it off. You mention to treat with Captan against brotytis blight, which is what I believe I have. How do I do that since the leaves cannot get wet? Do I soak the soil? Please reply petrafuhrmans@gmial.com. Thanks

I actually recommend wettable sulfur dust. A VERY SMALL amount of it. It is very difficult to treat African Violets once they get an infection, so most of the treatment will have to be preventative.
