U.S. sunflower growers have
another key tool in their box of herbicides.
DuPont has received a final label for Express® herbicide on
sunflower. Express can only be used on ExpressSunT hybrids that
have the Express tolerant trait.
Express controls or suppresses
most broadleaf weeds including Canada thistle. Express can be
applied from the 1 leaf stage up to the beginning of bud
formation. Grassy weeds are not controlled by Express.
A minimal amount of acreage will
be planted this season to ExpressSun hybrids in ND, MN and SD.
Production cannot be sold into the
market place until PNT approval is received from Canadian
authorities.
ExpressSun hybrids should be
available in all production states in 2008.
This label is the result of a
cooperative effort between DuPont, state university weed
specialists, IR-4, the ND Pesticide Control Board and the NSA.
