It is generally best to apply fungicidal products in times when the infected plant will be out of full sun and insect activity is low, such as in the early morning or evening. Serenade. This biological fungicide contains the bacteria Bacillus subtilis, which eats the fungus spores.
The acetic acid present in vinegar will change the fungus pH, killing the disease effectively. Try a baking soda solution (one tablespoon baking soda, one teaspoon horticultural oil, one teaspoon liquid soap in a gallon of water) on affected areas every one to two weeks.
2. Baking Soda for Fungal Disease Control. Gardeners often use baking soda as a fungicide to treat diseases such as powdery mildew, black spot on roses, and other fungal infections.
