e0“Dicamba-resistant (DR) soybean cultivars are essential elements in managing broadleaf weeds in modern production systems”
e2“At a dicamba dose of 1,152 g ae ha⁻¹, yield reductions reached 7% and 9% for Cultivars A and B, respectively, while the highest rate (1,440 g ae ha⁻¹) resulted in yield reductions of 12% (Cultivar A) and 14% (Cultivar B)”

Other claims from this paper (13)
- Intervention effect Visible injury in dicamba-resistant soybean increased with dicamba rate, reaching 18% (Cultivar A) to 20% (Cultivar B) at 1,440 g ae ha⁻¹ at 3 d after treatment.
- Intervention effect Dicamba injury symptoms in soybean declined to below 10% by 4 weeks after treatment.
- Intervention effect Chlorophyll fluorescence of soybean was not significantly affected by dicamba at 2 and 4 WAT.
- Intervention effect Height of soybean was reduced at 4 WAT only at the highest dicamba rate of 1,440 g ae ha⁻¹.
- Intervention effect Height differences in soybean disappeared by maturity.
- Intervention effect Dry biomass of Cultivar A soybean was reduced by 16% at the highest dicamba rate.
- Intervention effect Dry biomass of Cultivar B soybean was reduced by 10% at the highest dicamba rate.
- Intervention effect Pod reduction in dicamba-treated DR soybean was minor (<3.5%) and not significant.
- Intervention effect Dicamba applied from 288 to 864 g ae ha⁻¹ caused minimal soybean yield reductions below 5%.
- Intervention effect Dicamba applied from 288 to 864 g ae ha⁻¹ caused no significant biomass reduction in soybean.
- Intervention effect At 1,440 g ae ha⁻¹ dicamba, yield of Cultivar A soybean was reduced by 12%.
- Intervention effect At 1,440 g ae ha⁻¹ dicamba, yield of Cultivar B soybean was reduced by 14%.
- Recommendation The authors recommend adhering to recommended dicamba use guidelines, since applications above the tolerated rates can reduce soybean yield by up to 14%.
