I actually recommend peroxide over baking soda. Do one part peroxide to 2 parts water. Baking soda contains quite a bit of sodium which can be toxic to plants if used too much. Peroxide is a much safer alternative. You can add up to a teaspoon of dish soap to a gallon of water, but you usually won't even need that much. I will include a link to many ways to make your own fungicide, insecticide, and many other remedies here: https://www.gardeningknowhow.com/special/organic/
