Growers should look to apply a post-em Atlantis as soon as possible. This season there was protracted activity from pre-ems in many places so some black-grass plants will still be small and showing physiological effects so a timely application will make the most of this weakness now. Bad weather in late February and early March mean spray days are limited and workloads under pressure so be prepared to use any small windows to control black-grass.
