Soybean Rust Synopsis for 2007 - Anne Dorrance, Ron Hammond

Ohio’s sentinel plot system is designed to serve as an early warning system for the detection of both Soybean Rust and Soybean Aphid. This information is then adapted to Ohio for pest management recommendations. Plots were planted as early as the season allowed with a soybean variety that is ½ to a full maturity earlier than what is commonly planted in any given region. Data from the southern US during 2005-2007 indicate that once the plants begin to flower they are highly susceptible to soybean rust, during the normal production season.
For soybean rust leaves in the lower canopy were collected every 7 to 10 days during the season and shipped to OARDC in Wooster for analysis. All samples were kept in a moist chamber and then suspect lesions were examined under a dissection scope. Additional scouting was also done when spore traps detected soybean rust or models predicted that rust spores were in Ohio.

For soybean aphids scouts counted the presence of aphids on 20 plants in the plot each week if they were present.
All aphids and rust data was submitted to USDA PIPE site where nationwide observations can be found. Outputs and commentary were then posted www.sbrusa.net as well as http://corn.osu.edu/

New Soybean Rust Fungicide Guide – Now Online! - Anne Dorrance
Using Foliar Fungicides to Manage Soybean Rust(2nd Edition)can be found at http://oardc.osu.edu/soyrust/ This publication is authored by Dorrance, A. E., M. A. Draper, and D. E. Hershman, eds. 2007. This 111 page bulletin is available in print as Ohio Extension, Bulletin SR-2008.
There are two options here, one to download the whole document, which is 111 pages long or to download/look at each individual chapter. The fungicide recommendations have been modified from the first version capturing the data collected from US fungicide trials. These will continue to change as we are able to study the rust pathogen under US conditions. The most-up-to-date list of fungicides that are available to manage this disease are listed in Appendix B.
New chapters for this version include:
-Sentinel plots in the United States: Modeling the seasonal spread of soybean rust in North America
-Soybean growth and development
-Fungicide resistance management in soybeans
-Safe fungicide storage
-Alternatives for Organic soybean production.
-Influence of soybean rust on crop insurance that includes information on who will document good farming practices.
