1. What are the 5 strategies used to control worms in South Australia?

1. Use a strategic drenching program
2. WormTest at recommended times
3. Use grazing management to create low worm-risk paddocks
4. Breed and feed for worm-resistant goats
5. Manage drench resistance

2. What are the most important worms in this region?

The most important roundworms in this region are:

• Scour worms
  • Small brown stomach worm Teladorsagia (Ostertagia) circumcincta
  • Black scour worm Trichostrongylus vitrinus /Trichostrongylus colubriformis 
  • Thin-necked intestinal worm Nematodirus spp (only in young sheep)

In some or most years around Willalooka, Mundulla, Keith, Tintinara, Strathalbyn Plains, Adelaide Hills, Fleurieu Peninsula and coastal areas as well as isolated properties in the lower south east:

• Barber’s pole worm Haemonchus contortus

Very wet years generally cause higher burdens of all worms. These can be fatal without scouring occurring.
