e0“The greatest visual injury (80%), plant height reduction (65%), maturity delay (22 d), and soybean yield loss (96%) was caused by 1/10 of the dicamba label rate when applied at V7/R1 soybean growth stage.”

Other claims from this paper (9)
- Observation The three dicamba products similarly affected soybean injury, height, maturity, and yield.
- Intervention effect One-tenth label rate at V7/R1 caused 80% visual injury.
- Intervention effect One-tenth label rate at V7/R1 reduced soybean height by 65%.
- Intervention effect One-tenth label rate at V7/R1 caused 96% soybean yield loss.
- Observation V7/R1 was the most sensitive stage for yield reduction across dicamba products.
- Intervention effect Engenia at V2 or R2 caused 10% yield loss at 1.83 to 1.85 g a.e. ha −1.
- Intervention effect Engenia at V7/R1 caused the same 10% yield loss at 0.32 g a.e. ha −1.
- Observation Similar effective doses were estimated for Clarity and XtendiMax.
- Recommendation The authors recommend avoiding dicamba drift because GR soybean is sensitive to low rates of all three products.
