Fusarium root and crown rot
scouted June 10, 2022
- Scientific Name
- Fusarium sp.
- Background
- Soybeans in Duplin county, variety Asgrow AG69XF0, were scouted and observed 1% of the field was affected by damping off, dieback, browning, and wilting in random areas.The site is sunny. Prior to planting the field was only disked. No burndown was applied. The soybeans were planted behind rye. Roundup was applied around May 31.
- Conclusion
- The issue was identified as Fusarium root rot and Fusarium crown rot. Fusarium root rot is caused by Fusarium sp. Fusarium root rot can result in both pre- and post-emergence damping-off, leading to delayed emergence and stunting of infected seedlings. Fusarium crown rot can cause soybean seedling diseases, especially with wet conditions shortly after planting. These are more prevalent in poorly drained or compacted soils. Improving soil drainage may reduce stress and risk of infection.
