Aerial blight
scouted Sept. 7, 2022
- Scientific Name
- Rhizoctonia sp.
- Background
- Soybeans in Edgecombe county, variety AG 59XF0, were scouted and it was observed that 70% of the field was affected by leaf spot. The symptoms were widespread.
- Conclusion
- Aerial web blight, or aerial blight was identified as part of the issues affecting the plants in this field. It's caused by Rhizoctonia and while it's not a common disease for soybeans in the state it may cause local losses where conditions are conducive for development. Leaves, stems and pods may all be impacted. Some varieties are less susceptible but there is no host resistance. Rhizoctonia has a wide variety of hosts but corn and sorghum are poor hosts and rotating with those crops for two years may reduce incidence in future stands.
