1. What are the 5 strategies used to control worms in NSW Non-Seasonal Rainfall?

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 sheep
5. Manage drench resistance

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

The most important roundworms in this region are:

• Scour worms
• Black scour worm Trichostrongylus colubriformis /Trichostrongylus vitrinus (the latter increases in the south)

Also important but mainly for young sheep

• Thin-necked intestinal worm Nematodirus species
