Mark, I've been doing some more research and here are some other natural fungal sprays that might help.
1. Add 1 cup alfalfa meal to 1 gallon of water in a bucket. After a few hours, strain the mixture through cheesecloth. Add a dash of biodegradable dishwashing liquid to help the tea stick and spray the
plants.
2. Cut or tear 1/2 cup rhubarb leaves (about 6 leaves) into small pieces. Place the leaves in 3 quarts of water and bring to a rolling boil. Steep the leaves for at least an hour or overnight. Shred the boiled leaves further in a blender, if desired. Strain the solution through a cheesecloth and pour into a spray bottle to spray
plants.
3. Steep 3 cloves garlic (crushed), 1 onion (peeled and minced), and 1 teaspoon jalapeno peppper (crushed) in warm water for 1 hour or longer. Strain through cheesecloth. In the spray bottle, dilute 1 part of the strained liquid with 4 parts warm water and add 1 droop dishwashing liquid or 2 tablespoons horticultural oil. Mist
plants lightly.
4. Chamomile tea works against damping-off fungi that attack
seedlings, perhaps it would work on other types of fungi also. 1 tea bag per cup of boiling water. Let steep till it cools to room temperature. Spray.
