Asian soybean rust was found in 18 Alabama counties in 2004, 32 in 2005, 26 in 2006 and 40 in 2007. Predictions indicate that yield loss from soybean rust could reach 50% in the Southeast U.S., but the disease can be managed with fungicides. Fungicide applications can reduce yield loss, depending on the plant developmental stage, time when soybean rust is detected, and application method. This project will evaluate how best to use different timings and combinations of fungicides to control soybean rust.

The specific objective of this research project is to evaluate fungicide applications and management for control of soybean rust and other foliar diseases at multiple locations in...
