For the last couple of months I have been searching for an organic all natural fungicide recipe, and thought I was out of luck. But during an episode of Gardening By The Yard, Paul James shared his recipe for an all natural Fungicide Spray using Baking Soda. He mentioned that the recipe was originally created by Cornell University.
Paul James’ Famous Baking Soda Fungicide Spray Recipe:
- 1 gallon of water
- 1 tbsp baking soda
- 1 tbsp horticultural oil
- 1 tbsp insecticidal soap
- shake well and spry affected plants
- repeat every 7 to 10 days until cleared up
Baking soda is alkaline and can raise the PH levels of the soil if used in large amounts. Using baking soda from this recipe should not affect the soil. If treating plants that love high acidic levels, amendments to soil to bring the acidity back should be applied once or twice a year.
