Weed and crop safety of sulfonylurea herbicide–resistant BoltTM soybean
Sulfonylurea herbicide–resistant soybean, also known as BoltTM soybean, allows for the safe use of sulfonylurea herbicides such as thifensulfuron and chlorimuron and reduces the risk of soybean injury due to physical drift and carryover.
Field experiments were conducted near Clay Center, NE, USA, in 2016 and 2017 to evaluate weed control and crop safety in sulfonylurea/glyphosate-resistant soybean with herbicide programs, including but not limited to acetolactate synthase (ALS) inhibitors. ALS inhibitors are herbicides that interrupt a specific part of a plant’s developmental process.

Results of this study showed that sulfonylureas such as rimsulfuron/thifensulfuron in mixture with flumioxazin, saflufenacil plus dimethenamid-P, or metribuzin provided effective early season weed control and crop safety in soybean with BoltTM technology.
Additionally, soybean with enhanced sulfonylurea resistance offers greater crop safety in areas with an increased risk of drift from ALS-inhibiting herbicides or in double-cropping systems such as soybean after wheat. Currently, BoltTM technology is available with glyphosate-resistant soybean and is expected to be available with glyphosate plus dicamba-resistant soybean, which will further expand the scope of this technology.
