Yang coordinating sentinel soybean plots in 20 states

Tuesday, April 19, 2005

AMES, Iowa -- X.B. Yang, an Iowa State University plant pathologist, has received $389,000 to coordinate sentinel soybean plots in 20 states.

The funding will be used to plant and monitor soybean plots and provide an early warning system for Asian soybean rust.

"The goal of this project is to establish a monitoring and early warning system to guide soybean producers in making fungicide application decisions for Asian soybean rust control," Yang said.

The North Central Soybean Research Program and the United Soybean Board funded the two-year project, which started April 1. Researchers in each state will plant 20 sites of early maturing soybeans in 30-square-foot plots. The plots will be scouted intensively and provide an early warning system for growers.

"Soybean plants are more vulnerable to rust after flowering and the sentinel plots will be planted with early maturing varieties to alert researchers and producers if soybean rust is present in the region," Yang said.

Iowa State researchers began planting sentinel plots last week. Mark Honeyman, coordinator for the Iowa State research farms, said 11 of the plots are located on Iowa State research and demonstration farms.

"It's the perfect role for Iowa's public research farms and it is exactly why we are here," Honeyman said. "This is an excellent example of how a land-grant university serves the agricultural sector in the state."

Honeyman said the plots were planted early and will be protected, if needed, from frost. The early planting will provide an early-maturing crop that will be more susceptible to soybean rust spores.

Honeyman said can visit Iowa's sentinel plots located on research and demonstration farms near Ames, Castana, Chariton, Crawfordsville, Fruitland, Greenfield, Kanawha, Lewis, Nashua, Newell and Sutherland.

States participating in the project include Alabama, Arkansas, Florida, Georgia, Illinois, Indiana, Iowa, Kansas, Kentucky, Louisiana, Michigan, Minnesota, Missouri, Nebraska, North Dakota, Ohio, South Dakota, Tennessee and Wisconsin.
