While sodium bicarbonate has been shown to reduce to growth of mildews in lab tests, sprays containing only baking soda and water are not effective in controlling fungal diseases on infected plants, and high concentrations of sodium are harmful to plants. [17] Potassium bicarbonate is an effective low-toxicity fungicide against powdery mildew ...
Insecticidal soap is used to control many plant insect pests. Soap has been used for more than 200 years as an insect control.
