More on Group 4

Moves with the sugars

Taken in by the leaf, then carried with sugars down to the roots and up to the growing points.

Commonly used on

  • Broadleaf weeds
  • Kochia

Good to know

  • Almost always sold with a partner such as florasulam or fluroxypyr.
  • It is different chemistry, but it still counts as Group 4 in your rotation.
  • Group 4 resistant kochia has been confirmed on the Prairies. Keep drift and sprayer clean-out in mind around sensitive crops.

Same group, same mode of action

Not a rotation partner.
