The threat of Asian soybean rust (Phakopsora pachyrhizi) has led to unparalleled international cooperation and partnerships. The comprehensive North American soybean rust sentinel plot monitoring program put in place by the United States Department of Agriculture (USDA) is a good example. Ontario’s involvement in this innovative network resulted in a series of soybean sentinel plots (31 in 2007, 38 in 2006, and 44 in 2005) being established across the soybean production area of southern Ontario (from Windsor to Ottawa). The sentinel plot program involves intensive scouting for soybean rust symptoms and field evaluations by the Ontario Ministry of Agriculture, Food and Rural Affairs (OMAFRA) in conjunction with Agriculture and Agri-Food Canada. The establishment of these plots allowed us also to survey for other soybean pests, such as SCN, aphids, and other diseases. The information collected from this North American “early warning system” is posted on the Ontario Soybean Growers website (www.soybean.on.ca) and the USDA soybean rust website (www.sbrusa.net) as interactive, user friendly maps and commentaries. This monitoring program, in conjunction with educational outreach, spore trap data, prediction modeling, and fungicide development, gives producers the tools needed to track and combat this destructive disease and limit yield losses. The sentinel plot system provides producers, extension, consultants, and the soybean industry with an effective and successful decision support tool. Funding for this project was provided in part through the Canada-Ontario Research and Development (CORD) Program administered by the Agricultural Adaptation Council, the Ontario Soybean Growers, and the Ontario Soybean Rust Coalition.
