Target spot
scouted Sept. 7, 2022
- Scientific Name
- Corynespora cassiicola
- Background
- Soybeans in Moore county, variety 59XFO, were scouted and it was observed that 40% of the field was affected by Blight, browning, chlorosis, yellowing and leaf spots, in random areas of the field.
- Conclusion
- The cause of disease was identified as Target spot, caused by Corynespora cassiicola. This is a common pathogen in the state, but losses associated with it are rare. Infection requires high humidity and long periods of high moisture with free water resting on tissue surfaces. Cultural practices like crop residue destruction, managing weed hosts, and a crop rotation schedule that excludes hosts for several years are important to limiting disease losses.
