Chemical Action and Usages: Sulfur is a natural element that is toxic to fungus. It is available in several formulations including a RTU spray, wettable powder and dust. It is used for the control and prevention of black spot, rusts, leaf spots and powdery mildew on roses, other ornamentals, fruits and vegetables. It is also used less frequently as a miticide on some of the above. Sulfur disrupts the metabolic functioning of fungi and is one of the oldest known pesticides. For organic gardeners, sulfur is an important fungal disease control product. The Safer product listed contains the OMRI™ (Organic Materials Review Institute) seal of approval. Sulfur may be used on food crops up to one day of harvest.
