Description

Startect Oral Drench For Sheep – 5L

Startect Oral Drench For Sheep is a broad-spectrum, short-acting oral drench that effectively targets internal parasites, including worms resistant to older actives. Its unique combination of derquantel (10 mg/mL) and abamectin (1 mg/mL) makes it a vital option for modern resistance management, especially when rotating drenches to reduce long-term resistance risk.

Why choose Startect?

Startect contains derquantel a new active from the spiroindole (SI) class with no known resistance combined with abamectin to deliver dual-action parasite control. The deliberate pairing of these actives helps protect both ingredients from resistance and supports the sustainability of your drench program.
