Soybean rust was confirmed in southern Oklahoma this week and was reported in northern Texas last week. The spread of soybean rust westward this year was earlier than before and this is the first time we have seen rust this close to us this early in the year. This increases the likelihood that we will see soybean rust in Nebraska this year, but it will most likely be after the time when it could impact production.

As a result of these developments we have increased surveillance activity with the soybean rust sentinel plot program. The sentinel plot program is funded by the soybean checkoff and USDA. All findings with sentinel plots are reported on the national soybean rust Web site and the soybean rust phone hotline at 877-NebRust. While this most likely will not be a problem for production this year, we may get a chance to see it before it becomes a problem in future years.

To keep up with further developments of soybean rust and to track movement, check the national USDA Soybean Rust Web site at sbrusa.net. There is also a link to this site at the University of Nebraska–Lincoln Targeting Soybean Rust Web site.
