Soybean rust finds significant for future crop management
Iowa
As Iowa soybean growers finish harvesting the 2007 crop, Iowa State University has been scouting late planted fields for signs of Asian Soybean Rust. And they've found it in 14 counties across the state. Asian soybean rust has been confirmed in 2007 in Adair, Dallas, Des Moines, Fremont, Hancock, Iowa, Johnson, Lee, Muscatine, Polk, Pottawattamie, Ringgold, Story and Washington counties. Although the development of rust in Iowa fields happened too late in the growing season to cause any real damage, it is a significant discovery for soybean producers. "Discovering soybean rust in multiple counties clearly indicates that the disease reached northern production regions. Data suggest that the spores reached southwestern Iowa as early as August this year," says X.B. Yang, plant pathologist, Iowa State University. The discovery of rust in Iowa this year was no great surprise to some. Checkoff-funded research conducted at Iowa State University predicted the possibility. Dr. X. B. Yang has been refining a weather-based computer model to track the movement of rust spores from known infected locations and predicts where the disease may develop based on climate conditions. Iowa State University leads the field in these efforts. August rains are the likely culprit that sprinkled rust spores over Iowa soybean fields. When discovered, the disease was in its very earliest stages of development in most fields with the exception of Fremont County where disease development had progressed to 20 percent incidence. Those scouting for the disease are individuals from the Iowa Soybean Rust Team First Detectors, a group of 700 highly qualified crop professionals trained to identify the disease by Iowa State University through a partnership with the Iowa Soybean Association. Iowa State University and the soybean checkoff began training First Detectors during the summer of 2004, before rust was found in the United States. "Soybean producers need to continue to be vigilant and manage their soybean crop to optimize yield and profitability," says David Wright, director of contract research, Iowa Soybean Association. "Producers should increase the management of their soybean crop through increased scouting efforts."
