TARGET SPOT IN SOYBEANS

Agronomy Brief

Author: Shane Carver

Target Spot is a soybean disease caused by the Corynespora cassiicola fungi. Before 2010 it would have been considered a minor disease in soybeans in the Mid-South and Southeast regions of the United States. However, detection of the pathogen has significantly increased in recent years. Many would argue that it is one of the more prevalent diseases observed in soybeans in the South and in cotton fields. Susceptible cultivars can experience yield losses of up to 18 to 32% when favorable conditions are present but rarely result in significant yield losses in the Mid-South.
