Abstract

A summer drenching program for sheep worm control is now recognised as a key cause of drench resistance in Western Australia. However, some small changes can increase the sustainability of pre-emptive control programs. Drenches in summer should always be given to younger, growing sheep (current and previous year’s age groups), whereas adult sheep should be drenched in autumn, or if drenched in summer, some should be left untreated (if drenching at all). Research shows that this reduces the chance of developing drench resistance but still provides effective worm control.
