Pythium root and or crown rot
scouted Aug. 26, 2021
- Scientific Name
- Rhizoctonia solani
- Background
- Soybeans in Hyde county, variety Dynabro43XS7, were scouted and observed with 5% of the field affected by anker, dieback, browning, and leaf spot in patches. Besiege and boron were applied 2 weeks prior to sampling but no fungicide.
- 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.
