Dicamba-resistant soybean was developed and commercialized by Monsanto in 2016, and in recent years, barnyardgrass has become more troublesome for growers utilizing the dicamba technology with residual herbicides. Field studies were conducted from 2019 to 2021 in Stoneville, MS, to evaluate barnyardgrass control when glyphosate or glyphosate plus dicamba treatments were mixed with residual herbicides and barnyardgrass control with sequential herbicide applications, including glyphosate or glyphosate plus dicamba. In the first field study, glyphosate at 1,120 g ae ha-1 and glyphosate plus dicamba at 560 g ae ha-1 were applied in combination with common residual herbicides. The second field study included an initial treatment of glyphosate at 1,120 g ha-1, glyphosate plus dicamba at 560 g ha-1, and glyphosate plus dicamba plus S-metolachlor at 1,064 g ai ha-1 followed by a sequential treatment of glyphosate or glyphosate plus dicamba at 3 and 7 d after initial herbicide treatment. Results indicated glyphosate alone provided greater barnyardgrass control than glyphosate plus dicamba. Additionally, at 28 d after treatment (DAT), pyroxasulfone, pyroxasulfone plus fluthiacet, dimethenamid-P, and S-metolachlor did not affect postemergence (POST) control of barnyardgrass with glyphosate plus dicamba treatments. Furthermore, sequential herbicide treatments of glyphosate or glyphosate plus dicamba led to no difference in barnyardgrass control 28 d after the sequential treatment. These results indicate that options exist for adding residual herbicides to glyphosate plus dicamba treatments and that sequential treatments of glyphosate or glyphosate plus dicamba are important for optimizing barnyardgrass control.
