scouted Aug. 25, 2021
- Scientific Name
- Pythium sp.
- Background
- Soybeans in Union county, variety P55A49, were scouted and observed with 5% of the field being affected by defoliation, leaf spot, as well as browning and yellowing between the veins.
- 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.
