Belkar®
Herbicide
Belkar® is a post-emergence autumn applied herbicide for use on winter oilseed rape. It is highly effective against key weeds such as cleavers, cranesbill, fumitory, poppies and shepherd’s purse.
Belkar contains Arylex™ active, a new active ingredient for oilseed rape, together with the well-established active ingredient picloram. It delivers robust and reliable control of key problem weeds in variable temperatures with a flexible window of application from September to the end of December.
