Jim Marois, left, and David Wright, professors at the University of Florida’s North Florida Research and Education Center in Quincy, check soybean plants for Asian soybean rust - Friday, July 1, 2005. First discovered in the United States in fall 2004, the crop-killing disease was found growing on cultivated soybeans for the first time this week, at early-planted "sentinel plots" in Florida and Alabama. To help protect the nation’s $16 billion soybean crop, UF researchers are monitoring plants around the state for signs of the disease.

Successful weed control is one of the most important practices for economical soybean production in Florida. This 10-page publication discusses weed control methods for soybean growers. Written by J. A. Ferrell, G. E. MacDonald, and P. Devkota, and published by the UF/IFAS Agronomy Department, revised January 2021.
