Summer drenching has been the foundation of effective worm control now for many years. This is a very effective way to reduce worm number and this will lead to improved worm control in the following autumn and winter. There can be a double-edged sword with summer drenching, the potential to accelerate resistance. Since summer drenching can help accelerate resistance a highly effective, short acting drench should be used.
The timing of your first summer drench generally coincides with “haying off” of pasture and/or weaning of spring lambs. It is always important to remember to use worm tests to aid with drenching decisions. We have worm test kits available for your use.
The use of stubbles that have been stock free all year aid greatly in your worm control program. So come in or call for an on-farm visit to evaluate your summer drench plan.
