Queensland worm update - March 2012

Maxine Lyndall-Murphy, WormBuster Lab, Brisbane, (

And the wet season continues…sheep marooned on high ground will be vulnerable to severe Barber’s Pole infestations and will need to be drenched. In the pastoral regions many drenches are still efficient. This contrasts with the situation in the more easterly sheep regions where only a few drenches are still efficient enough for use in acute infestations.

At this time of the year infestations are often acute and treatment needs to remove the entire worm burden. A 90% reduction of a worm burden tested at 5000epg leaves a count of 500epg.

Keep checking drenches with a Day 10-14 DrenchCheck.

The Barber’s Pole situation has slowed right up at home. Last two mobs WEC’s of 50 and less than 50epg respectively. Clients report similar situations. A client who has just learned to do their own worm egg counting e-mailed to report that everything was going well, the microscope was proving a great management tool and that they should have done it years ago!
