t0“Injury Criteria Associated with Soybean Exposure to Dicamba”
e3“Injury 15 DAT was equivalent to the nontreated control for dicamba rates as high as 4.4 g ha –1 for lower stem base swelling at V3/V4 and for upper canopy leaf rollover/inversion and terminal leaf necrosis at R1/R2; for rates as high as 8.8 g ha –1 for leaf petiole base swelling and stem epinasty at R1/R2, and lower stem base lesions/cracking (V3/V4 and R1/R2 average); and for rates as high as 17.5 g ha –1 for lower leaf soil contact at V3/V4 and leaf petiole droop at R1/R2”

Other claims from this paper (14)
- Observation Field research identified 14 injury criteria associated with dicamba in soybean.
- Observation Greatest 15 DAT injury in soybean was observed for upper canopy pale leaf margins (3.8 to 4.2) at V3/V4 with dicamba at 0.6 to 4.4 g ha –1.
- Observation Greatest 15 DAT injury in soybean was observed for terminal leaf cupping (4.1 to 5.0) at R1/R2 with dicamba at 0.6 to 4.4 g ha –1.
- Observation Greatest 15 DAT injury in soybean was observed for upper canopy leaf cupping (3.8 to 4.8) at V3/V4 with dicamba at 0.6 to 8.8 g ha –1.
- Observation Greatest 15 DAT injury in soybean was observed for upper canopy leaf surface crinkling (3.4 to 4.4) at V3/V4 with dicamba at 0.6 to 8.8 g ha –1.
- Intervention effect Lower stem base swelling at V3/V4 at dicamba rates up to 4.4 g ha –1 was equivalent to the nontreated control.
- Intervention effect Terminal leaf necrosis at R1/R2 at dicamba rates up to 4.4 g ha –1 was equivalent to the nontreated control.
- Intervention effect Leaf petiole base swelling and stem epinasty at R1/R2 at dicamba rates up to 8.8 g ha –1 were equivalent to the nontreated control.
- Intervention effect Lower stem base lesions/cracking at dicamba rates up to 8.8 g ha –1 was equivalent to the nontreated control.
- Intervention effect Lower leaf soil contact at dicamba rates up to 17.5 g ha –1 was equivalent to the nontreated control.
- Intervention effect Leaf petiole droop at R1/R2 at dicamba rates up to 17.5 g ha –1 was equivalent to the nontreated control.
- Association Visual injury and plant height reduction rose steadily with increasing dicamba rate, in contrast to the injury criteria (0 to 100%).
- Observation Moderate to severe injury at dicamba 0.6 to 4.4 g ha –1 corresponded to soybean yield loss of 1% to 9% when applied at V3/V4.
- Observation Moderate to severe injury at dicamba 0.6 to 4.4 g ha –1 corresponded to soybean yield loss of 2% to 17% when applied at R1/R2.
