Other claims from this paper (8)
- Intervention effect Soybean was most susceptible to 2,4-D injury between 413 and 1,391 GDD, approximately V1 to R2.
- Intervention effect Maximum soybean yield-loss susceptibility to 2,4-D occurred between 624 and 1,001 GDD, V3 to V5.
- Intervention effect Soybean visible injury sensitivity to dicamba extended from 0 to 1,162 GDD, emergence to R2, longer than for 2,4-D.
- Intervention effect Soybean height was most affected by dicamba exposure between 847 and 1,276 GDD, V4 to R2.
- Intervention effect Soybean grain yield was most susceptible to dicamba between 820 and 1,339 GDD, V4 to R2.
- Recommendation The authors recommend considering specific exposure growth stage when evaluating off-target herbicide injury.
- Recommendation Dicamba application near susceptible soybean at V4 to R2 should be avoided.
- Recommendation Soybean herbicide sensitivity research should use multiple exposure times and avoid generalizing stages as vegetative or reproductive.
