The Environmental Protection Agency has registered Taviuim Plus VaporGrip Technology, a premix from Syngenta that contains dicamba and S-metolachlor. State registrations are pending.
The premix can be used preplant, at planting and early post-emergence on Roundup Ready 2 Xtend soybeans and Bollgard II XtendFlex cotton, according to a Syngenta news release.
Tavium contains built-in residual control, offering up to three weeks long residual than dicamba alone. It provides broad-spectrum control of grasses and broadlead weeds, including those resistant to ALS, PPO and glyphosate herbicides, according to the release.
To preserve the efficacy of auxin herbicides, such as dicamba, Syngenta recommends using Tavium as part of a two-pass program following a pre-emergence application of a residual.
“The premix formulation provides an easy way to reduce selection pressure on dicamba, but a system of pre- and post-emergence herbicides is still crucial,” Bobby Bachman, Syngenta herbicide product lead, said in the release. “Practicing sound resistance management principles – such as starting clean and using diversified management and agronomic practices – will help growers be good stewards of the technology.”
Dicamba belongs to the Weed Science Society of America’s Group 4. S-metolachlor belongs to the WSSA Group 15.
