scouted Sept. 1, 2022
- Scientific Name
- Pythium sp.
- Background
- Soybeans in Wayne county, variety s61-m2x, were scouted and it was observed that 10% of the field was affected by dieback, browning and yellowing between the veins, leaf drop, and stem rot in patches in the field.
- Conclusion
- The issue was identified as Pythium root rot and/or Pythium crown rot. This disease is caused by Pythium sp. Pythium root rot and crown rot can result in both pre- and post-emergence damping-off, leading to delayed emergence and stunting of infected seedlings. Prevalence tends to increase in warm and moist, but not saturated soils. This pathogen is an oomycete.
