Alternator Met is valuable tool for grass weed control in winter barley and winter wheat. Suitable for use at pre-emergence and as a residual top up, it is composed of metribuzin, flufenacet and diflufenican. The addition of metribuzin to flufenacet provides improved grass weed and broad-leaved weed control compared to Liberator.
Metribuzin like flufenacet is predominantly root acting but it also has some foliar activity which may make it particularly useful for top up applications. The addition of metribuzin provides up to 10% more black-grass control at the full rate compared to straight Liberator.
The three-way co-formulation provides a simple and effective tool to control weeds in cereals throughout the autumn establishment period.
