What Farmco Recommends It For:
Farmco recommends Q-Drench® for strategic, high-efficacy treatments such as weaning, pre-lambing, quarantine, primer and exit drenches. It’s ideal when producers need maximum effectiveness to protect flock health and delay the development of drench resistance.
Why It’s a Farmco Favourite:
Farmco favours Q-Drench® because its four-way combination delivers exceptional broad-spectrum control, targeting parasites through four different modes of action. Developed in Australia for Australian conditions, it offers reliable performance, strong resistance management, and excellent value for producers needing confidence at key drenching points.
Q-Drench®
Multi-Combination Drench for Sheep
Q-drench Is the Ideal Choice for Strategic Treatments Such as Weaning, Pre-lambing, Quarantine, Primer and Exit Drenches Which Rely on the Highest Possible Efficacy to Achieve Their Aims. It Was Developed in Australia for Australian Sheep Producers and Contains 4 Actives with 4 Different Modes of Action at 4 Fully Effective Doses. Using Q-drench as Part of or Within a Season Drench Rotation Will Increase Sheep Productivity and Help Delay the Development of Parasites Resistance to Existing Drenches.

- Effective against lung worm and tapeworms
- Effective against mature and late immature (from 6-week stage) liver fluke
- Effective against nasal bot and itch mite
Recommendations for Use
- Entry or primer drench
- Exit or tail cutter drench
- Pre-lamb drench
