15 FEBRUARY 2002 ------------------------- INHIBITOR KNOW-HOW KNOW your ALS-inhibitor herbicides and their restrictions to avoid shooting yourself in the foot with herbicide choices later in

the season, advises Morley Research Centre director and Weed Resistance Action Group chairman Jim Orson. "It is becoming something of a nightmare with tank-mixes and sequences. You

have to know your likely herbicide programme before you start the season. Then you can plan spring use." lFor a detailed chart on permitted ALS-inhibiting herbicide sequences and
