Herbicide Injury
scouted Aug. 17, 2026
- Scientific Name
- Herbicide Injury
- Background
- A soybean field in Columbus County was being scouted, and it was observed that 75% of the field was affected by leaf distortion and stunting. A sample was submitted to the PDIC for diagnosis.
- Conclusion
- The issue was identified as herbicide injury. The issue was identified as herbicide injury, specifically consistent with exposure to a growth regulator (auxin-type) herbicide. These herbicides usually cause abnormal growth patterns in soybeans, including leaf cupping, strapping, puckering, and distortion of newly developed leaves. It may take up to 21 days for soybeans to show signs of this type of injury
