Liberator is the first step to effective grass-weed and broad-leaved weed control in winter wheat, winter barley, spring wheat and spring barley.

Product details

Effective control of grass-weeds requires a robust herbicide programme. Liberator provides the crucial first step in that programme, with excellent pre-emergence control of black-grass and other grass-weeds, plus a range of broad-leaved weeds.

When used as a pre-emergence herbicide, Liberator reduces the number of weeds that a post-emergence herbicide – such as Atlantis Star – has to control.  This improves overall weed control while reducing the potential to select for resistant weeds.
