Midwest May Have Avoided Soybean Rust

posted on August 26, 2005

After it was first spotted in America last year, Asian soybean rust has largely avoided Midwestern fields. The fungus, known for causing premature leaf loss and lower crop yields has been confined to southern sections of the U.S.

Experts on soybean rust contend the fungus did not spread northward because of air currents that pushed spores away from the Midwest. But the lack of confirmed sightings in the Heartland does not mean spread of the fungus will not happen next year.

With Asian soybean rust isolated in southern states like Florida and Georgia, the fungus likely will survive another winter. And under certain weather conditions, the rust may spread northward.
