You might want to check the internet for Phyton 27 (not to be confused with Physan 20) and invest in the smallest bottle you can find. Then just save it for the ocasional problem like this. I have an occasional infection that starts with a rosey red color in the leaves and in the past has always progressed to the death of the plant (Catts). The latest one has been sprayed with this stuff about once every two weeks , I think three times now, and 7 to 8 weeks later, the desease is not progressing. I mix up about a 1/4 tsp at a time (don't remember if this was with 1 or 2 cups of water, but I keep the Phyton container marked with the ratio), so it looks like my 8oz bottle will last a pretty long time, as sometimes I can go 6 months without its use, and I have a LOT of plants.
