Influence of Tiger 90 Sulphur on Potato Scab

“As early as 1897 Wheeler and Adams demonstrated that applications of elemental sulphur (S) to soil would control potato scab.” It appears that the mechanism for control comes from the reduction in soil pH. Elemental sulphur products such as degradable Tiger 90CR can aid in reducing the infection levels of common scab caused by the (Streptomyces scabies) in prairie soils.
