Cyrex^PS Liquid Sheep Blowfly and Lice Treatment

Active Ingredients: Spinosad @ 12.5g/L & Cyromazine @ 500g/L

Cyrex^PS Liquid is a dual-active jetting fluid and blowfly strike dressing that prevents blowfly strike, treats existing strike and controls lice on sheep with long wool. This unique formulation combines spinosad and cyromazine, two established active ingredients with different modes of action for potent knockdown and residual control of maggots and lice.

Cyrex^PS Liquid Sheep Blowfly and Lice Treatment contains Spinosad @ 12.5 g/L and Cyromazine @ 500 g/L.

It is registered for;

The control of Spinosad-susceptible strains of lice (Bovicola ovis) for 8–11 weeks on sheep with long wool.
The protection of long wool sheep for up to 14 weeks from strike by the cyromazine-susceptible strain of blowfly (Lucilia cuprina), including organophosphate-resistant strains, when applied by jetting.
The treatment of blowfly strike in sheep.

Why is the unique formulation of Spinosad and Cyromazine used in Cyrex^PS so effective for blowfly strike and lice control on sheep?

Spinosad (used in Extinosad Eliminator) provides knockdown control of flies, maggots and lice. Extinosad Eliminator remains the benchmark for knockdown control of maggots, flies and lice with maximum flexibility.
- Spinosad belongs to the spinosyn chemical family.
- Upon contact or ingestion, spinosad causes involuntary and prolonged tremors in the nervous system of target parasites, leading to irreversible paralysis and death.
- Spinosad provides knockdown control of adult and nymph lice.
Cyromazine (used in Vetrazin Liquid) provides residual protection against blowfly strike. Vetrazin Liquid has been a trusted jetting solution for long-lasting protection against blowfly strike in sheep for more than 40 years.
- Cyromazine is an insect growth regulator.
- It interrupts the lifecycle of blowflies by preventing first-stage larvae from moulting into damaging second-stage maggots or maturing into adult flies.
- Cyromazine prevents 1^st stage larvae from moulting into damaging 2nd stage maggots and provides long-lasting residual activity.

Why should you be using Cyrex^PS Liquid this season?

A Dual active blowfly strike dressing:

- Spinosad provides rapid knockdown control of maggots, while cyromazine prevents first-stage larvae from moulting into damaging second-stage maggots or maturing into adult flies.

- Cyrex^PS Liquid is also registered for the control of lice for 8–11 weeks in long wool when applied as a jetting fluid.
