research trials form the basis for fungicidal recommendations in the U.S. Recent research from Washington State University indicates that the herbicide Glyphosate may be effective in dealing with the fungus. Rust-resistant varieties of soybeans are currently in development by both public universities and private industry. In some regions, the selection of winter cover crops and forage legumes may be effected, since they can serve as host plants. Resistance genes (Rpps) have been identified and host resistance is expected to be an effective, long-term solution for soybean rust in the future. Until resistant commercial varieties are in place, the management of rust depends on judicious use of fungicides. When untreated, soybean rust causes yield losses due to premature defoliation, fewer seeds per pod and decreased number of filled pods per plant.
