The Provisia Rice System will provide a new tool for post-emergence control of a broad range of grass weeds, including ALS-resistant grasses, weedy rice and red rice. It has been developed through traditional breeding techniques.
Registration is anticipated as early as 2016 in the US, with other countries to follow.
The new system comprises Provisia seed containing the Provisia trait, which allows farmers to safely apply Provisia herbicide: an ACCase or group 1 herbicide site of action.
Although Provisia herbicide will initially control grass weeds, BASF is working on combinations with other herbicides that will also provide control of broadleaf and sedge weeds.
“This new system will provide a different site of action, helping rice growers control ALS-resistant weeds,” said Jason Kuhlemeier, technical market manager, BASF. “It was designed to be used as a companion to the Clearfield Production System for rice, allowing growers to rotate herbicide sites of action for controlling grass weeds including weedy rice and red rice. This provides a sustainable system to manage the risk of developing weeds that are resistant to available herbicides.”
BASF began initial research on this new system in 2008 and filed patent applications in 2009.
