Summary:
Soybean rust, caused by the fungus Phakopsora pachyrhizi, is the most serious foliar disease of soybean worldwide. The disease was first detected in North America in November, 2004, causing great alarm among stakeholders. In response, the USDA, growers organizations, LGUs and state departments of agriculture established the soybean rust sentinel plot network to follow the spread of the disease throughout the growing season and to use this information as a basis for making appropriate soybean rust management decisions. The system has worked very well, saving soybean growers an $209-299M each year by: 1) providing early warning to soybean producers in the southern U.S. of the need to spray fields to protect their crop yields and 2) nearly eliminating unnecessary fungicide sprays targeting the disease. Due to the fact the yield losses caused by soybean rust have been restricted to a few states in the deep South, as well as a consistent pattern of late-season appearance of soybean rust in some southern and all northern states since 2005, there has been a substantial reduction in the perception of risk from soybean rust, especially by stakeholders in the North Central and Northeast regions. At the same time, USDA funding for soybean rust monitoring became unavailable in 2009. Reduced funding for the sentinel network, as well as reduced stakeholder perception of soybean rust risk, has forced the network to downsize substantially. In anticipation of a reduced monitoring network, preliminary network and econometric based analyses have been conducted by independent university research groups to develop rational strategies for optimizing the location of sentinel plots to reduce costs while maximizing the utility of the information obtained from a reduced monitoring system. We seek funding from the Southern Region IPM Center IPM Enhancement Grants Program for a workshop to: 1) develop a strategy to integrate the network and econometric analyses for optimizing sentinel plot locations with epidemiology based models of soybean rust spread; and 2) develop a research proposal for conducting an integrated, multidisciplinary analysis for optimizing the placement of sentinel plots in the southern U.S., but for the benefit of both southern soybean growers and the national soybean industry. Failure to find ways to optimize future soybean rust monitoring activities could have catastrophic consequences in the event that funding is furthered reduced. We plan to submit the research proposal to one or more of the regional IPM Centers in the next funding cycle. This work, which has broad stakeholder support, has implications for other important diseases, such as Ug99 wheat stem rust and southern corn rust, both of which may require extensive monitoring programs in the U.S. This Seed Grant has broad stakeholder support. In addition, the grant specifically addresses a priority in the National Road Map for IPM: Develop economical high-resolution environmental and biological monitoring systems to enhance our capabilities to predict pest incidence, estimate damage, and identify valid action thresholds.
Objectives: Conduct a planning workshop to bring together researchers who are currently applying network, econometric, and epidemiological models to optimize soybean rust monitoring efforts in the U.S. with key Extension Specialists to: 1) develop a strategy to integrate the network and econometric analyses for optimizing sentinel plot locations with epidemiology based models of soybean rust spread and 2) develop a research proposal for conducting an integrated, multidisciplinary analysis for optimizing the placement of sentinel plots in the southern U.S. for the benefit of both southern soybean growers and the national soybean industry. We plan to submit the research proposal to one or more of the regional IPM Centers in the next funding cycle |

Final Report: |
|
Impacts Soybean producers will potentially $200M dollars annually as a result of our ability to continue to successfully monitor soybean rust using a scaled down, strategic monitoring network. Savings are the result of pesticides not being applied when not needed, and the appropriate application of pesticides when the soybean rust risk is high. |
