When someone mentions rust to blackberry growers, what usually comes to mind is the devastating orange rust disease. However, there are two rust diseases observed in southern blackberry production – orange rust and cane and leaf rust. We are not sure if leaf rust is being seen in other regions of the country than the South, but we want to share info with growers across the US. It is very important that one be able to distinguish the two, as the control recommendations are very different.
