Late-season soybean rust affects 11 counties

By Peter Hull

Soybean rustSoybean rust was found in 11 South Carolina counties in 2009: Aiken, Bamberg, Barnwell, Berkeley, Calhoun, Colleton, Dorchester, Hampton, Lee and Orangeburg.

Soybean rust is a disease that causes early maturation and severe loss of yield through damage to the leaves and decreased seed weight.

Cool, wet weather helped spread the disease, but with fields in the latter stages of maturity, the late-season spread did not affect soybean crops, said John Mueller, Extension plant pathologist and director of the Edisto Research and Education Center in Blackville.

Rust was found on soybeans last year across the Southeast from Florida to Texas. The disease also made its way to Illinois, Indiana and Missouri, among other states.
