Ring spot usually affects only the older leaves, and therefore is considered a minor disease. However, correctly identifying the disease in the field can help to reduce unnecessary chemical sprays. This 2-page fact sheet outlines the symptoms and spread of the disease, as well as how to prevent and control Sugarcane Ring Spot. Written by P. Rott, J.C. Comstock, H.S. Sandhu, and R.N.
