Sulfur Role in Plant Diseases Management

Ghasemi K. 2018. Sulfur role in plant diseases management. Plant Pathology Science 7(1):63-72. Abstract : Sulfur (S), as a promoter of plant defense system and fungicidal effect, can have a critical role in organic farming. Presence of sulfuric defense compounds including elemental sulfur, H2S, glutathione, pytochelatins, secondary metabolites and S-rich proteins are vital under stress conditions. As a soil disinfectant, carbon disulfide is widely used against soil-borne pathogens. This is used for controlling the root and crown rot disease caused by Armillaria. Sulfur fumigation is used against powdery mildew in greenhouse production. Fumigation and application of sulfur pad are methods for controlling the grape and some other fruits rot in storage. Besides, sulfur is effective in control of mites, psyllids, and thrips.
