EPA Approves Syngenta’s Tavium Plus VaporGrip Dicamba Herbicide
Tavium Plus VaporGrip Technology herbicide from Syngenta has received registration from the U.S. EPA for use in cotton and soybeans.
According to the company, Tavium is the market’s first premix dicamba herbicide containing built-in residual control to help manage resistant weeds and maintain clean fields throughout the season. A proprietary Syngenta premix, the product will be available for the 2019 growing season, subject to state approvals.
Tavium can be used preplant, at planting and early post-emergence on Roundup Ready 2 Xtend soybeans and Bollgard II XtendFlex cotton. The premix of dicamba and S-metolachlor provides a convenient new tool to manage key ALS-, PPO- and glyphosate-resistant broadleaf and grass weeds.
“Unlike all other stand-alone dicamba products, the multiple effective sites of action in Tavium broaden the activity spectrum and increase its overall efficacy and sustainability,” said Bobby Bachman, herbicide product lead at Syngenta. “The addition of S-metolachlor with dicamba in a premix not only helps manage resistance, but it offers up to three weeks longer residual control than dicamba alone.”
Tavium targets driver weeds such as Palmer amaranth, waterhemp, horseweed (marestail), common and giant ragweed, kochia, morningglory, barnyardgrass and foxtail. The product is formulated to:
- Manage emerged weeds through contact activity
- Control weeds that have yet to emerge with residual activity
- Provide up to three weeks longer control than dicamba alone
- Work in all tillage systems and various geographies in both pre- and early post-emergence applications
To help preserve the efficacy of auxin technologies like dicamba, Syngenta recommends applying Tavium in a two-pass system, following a pre-emergence application of Boundary 6.5 EC, BroadAxe XC or Prefix herbicides in soybeans or after Caparol 4L herbicide in cotton.
“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,” Bachman said. “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.”
