Asian soybean rust (Phakopsora pachyrhizi) is a new and invasive fungal disease of soybean in North America. Establishment of the disease in the southern United States and Mexico poses a significant risk to Ontario and Canadian soybean production. The true extent to which soybean rust threatens Canadian soybean production, however, will not be known for a few more years. Early detection is critical to managing soybean rust and, thus, efforts were made to monitor the movement of soybean rust into Ontario through sentinel plots and spore trapping (passive/active). The Ontario sentinel plot program was set up in conjunction with the comprehensive monitoring program put in place for the 2005 and 2006 growing seasons by the United States Department of Agriculture (USDA), the United Soybean Board (USB), and the North Central Soybean Research Program (NCSRP). A series of soybean sentinel plots (38 in 2006 and 44 in 2005) were established across the soybean production areas of southern Ontario (from Windsor to Ottawa). The sentinel plot program involves intensive scouting for symptoms and field evaluations by the Ontario Ministry of Agriculture, Food and Rural Affairs (OMAFRA), Agriculture and Agri-Food Canada (AAFC), and industry partners. In 2006, we established a preliminary network of rainfall collectors (10) and passive Syngenta Spore Tracker (2) traps to assist in the detection of Asian soybean rust spores in Ontario/Canada. The sentinel plots and spore trapping networks provide an effective early warning system and a decision support tool for producers and advisors considering fungicide applications. Funding for this project was provided in part by Agriculture and Agri-Food Canada through the Agricultural Adaptation Council’s CanAdvance Program and the AAFC Pest Management Centre, the Ontario Soybean Growers, and the Ontario Soybean Rust Coalition.
