Has anyone ever had an parasitic algae? its starts off from small brownish spot and gets bigger, kinda of transparent. When I first notice the problem I sprayed the plant with liquid copper and took some leaves to the agriculture extension service. The leaves that I sprayed the algae was dead. At that time the lady told me it was a fungus. So, I checked the plants I took to the sale and seen nothing on them. [ plants were sprayed twice with liquid copper ] a few days later I noticed it on more plants, so I went back to the ag station and had someone else look at it. This time there was a white mildew looking spot on the leaf. The lady in charge said I had an parasitic algae with a secondary fungus. She told me to keep spraying with liquid copper. She said it was because we had a very wet summer. so, anyone that got one of my plants should keep it away from other plants and spray again with liquid copper. I have never heard of a parasitic algae, has anyone else ever had this problem?
