White Rusts of Crucifers

Abstract

The white rusts occur worldwide and are best known and most common on the Cruciferae. Spinach, radish, turnip, horseradish, and mustard are common economic hosts, whereas cabbage, brussels sprouts, salsify, and cauliflower are less affected. These diseases are also common on many cruciferous weeds but are less well-known on sweet potato and species of the Capparidaceae and Amaranthaceae.
