Tips for Best Results
- Weigh animals accurately — never estimate liveweight. Underdosing is one of the most common causes of treatment failure and accelerates drench resistance in your herd.
- Benzimidazole (BZ/white drench) resistance awareness — BZ resistance is well established in cattle worm populations across parts of Australia, particularly in Cooperia spp. and Haemonchus. Use a Drench Efficacy Test (DrenchCheck or faecal egg count reduction test) to confirm Panacur 100 is still working effectively on your property before relying on it as a sole treatment.
- Refugia management (WormBoss principle) — avoid treating every animal in the mob at every drenching. Leaving a proportion of low-risk animals (those in good condition and not showing signs of worm burden) undrenched maintains a population of worms in refugia — worms that have not been exposed to the drench. This slows the development and spread of resistance on your property, which is a key WormBoss recommendation for sustainable worm management.
- Rotate drench classes strategically — rotating to a different drench class (e.g., a macrocyclic lactone or combination product) based on resistance test results, rather than on a fixed calendar rotation, is the recommended approach. Talk to the team at TGRM on (07) 5482 1692 for advice on building a drench resistance management plan suited to your property.
- Storage — store below 25°C out of direct sunlight. Keep out of reach of children and animals. Check the expiry date before use.
- Record keeping — record the date, product used, batch number, animals treated, and bodyweights drenched to. Good records support resistance monitoring and aid in calculating withholding periods accurately.
Always read the label and follow directions for use. The registered label is the legal document governing use of this product.
