Bleach at low concentrations can be effective, see b54red's thread about it. I have used hydrogen peroxide with success, however it is not cost-effective for more than a few plants.
I think a lot of the organic approaches to fungicide have to do with changing the ph on the leaf surface, creating an unfavorable environment for the disease to grow. Diluted milk is one treatment that comes to mind. |
