Pro-Active Dual Drench Technology
The first drench in history designed to protect itself against resistance from the beginning

Proven in more than 200 farm trials5
Extensively road tested across Australia to confirm that Startect works where others fail

Prolongs the useful life of older drenches
When used as the cornerstone of your drench program

Startect: The new sheep drench that improves sustainability through better resistance management

Startect marks the first time that an entirely new class of sheep drench has been released in combination to better protect itself against resistance1. Startect contains derquantel, the first active from the new SI class (Spiroindoles), purposely combined with the powerful ML abamectin.

fragile drenches, giving more drenching options in future.3

A 28-day ESI (Export Slaughter Interval)4 allows speed to market and trading flexibility.

Startect delivers producers a new level of confidence when it comes to drenching and staying a step ahead of resistance.

Clik Blowfly

Insect growth regulator for prevention of blowfly strikes in sheep

Description and Composition

CLIK is a ready-to-use spray-on/pour-on formulation containing 50 g dicyclanil per litre


Dicyclanil, the active ingredient of CLiK, is an insect growth regulator belonging to the group of pyrimidinamines. Dicyclanil interferes with the chitin metabolism of the insect, in a way that is not yet exactly known. Treated larvae will therefore be unable to moult to the next stage. The molecule shows a high specificity for Dipteran fly larvae.

CLiK is to be used exclusively in a preventative way; i.e. the flock must be treated prior to an anticipated fly wave. First instar larvae are much more susceptible to dicyclanil than second and third instars, and established strikes may thus not be immediately cured.


CLiK is a ready-to-use spray-on/pour-on formulation for the prevention of blowfly strikes (Lucilia sericata, L. cuprina and Wohlfahrtia magnifica) in sheep.

Dosage and administration

The recommended dose rate is of 30 to 100 mg a.i. / kg bodyweight (0.6 to 2 ml of CLiK / kg bodyweight), according to the sheep weight and the type of strike. For further details, please refer to local label recommendations.

The protection period following a CLiK application will be of 16 to 24 weeks according to local conditions.

Withdrawal periods

Withdrawal periods according to national registrations.


Coopers Blowfly and Lice

Rapid knock down of maggots on struck sheep

Protects sheep against blowfly strike for up to 12 weeks

Treats lice in long woolled sheep

Moderate rainfall does not affect efficacy








VETRAZIN SPRAY ON is a spray-on insect growth regulator (IGR) for the prevention of fly strike in sheep. VETRAZIN SPRAY ON is a ready-to-use, low-volume formulation. The active ingredient in VETRAZIN SPRAY-ON is cyromazine, which cases retardation, malformation and death of young fly larvae.

WITHHOLDING PERIODS Wool- 2 months Meat- 7 days Milk- Do not use on sheep which are producing milk or milk products for human consumption. ESI- 21 days 

                                                Active: 60g/L Cyromazine


Graziers’ know that during humid summer months monitoring of sheep for fly strike is needed. The main purpose of an insecticidal dressing fluid is fast activity on maggots followed by protection of the healing wound from fly strike. The longer residual activity the greater comfort graziers’ will have when monitoring their flock post-treatment.

Deadmag dressing fluid is an organophosphate insecticide formulated for Australian conditions. During the warm summer months it will provide quick eradication with 4-8 hours by working on the nervous system of the blowfly followed by residual activity for up to 21 days.



For the control of susceptible body lice Bovicola ovis on shorn sheep up to 7 days off-shears and unshorn lambs up to 2 months of age. This product can be expected to protect sheep against re-infestation with lice for 4 weeks after treatment when applied within 24 hrs of shearing.


Extinosad Pour-On

Features and benefits

·         Off-shears or long wool

·         Kills SP and IGR resistant strains(3)

·         Kills lice within hours

·         Nil wool withholding period

·         Unique mode of action

                                                ·         Ideal for rotation programs

                                                ·         Ready-to-use formulation

Registered indications

Extinosad Pour-On is registered for the control of lice (Bovicola ovis) in sheep, both off-shears and with long wool, including strains that are resistant to synthetic pyrethroid (SP) compounds.

How Extinosad works

Extinosad contains the active ingredient, spinosad, which is derived from the naturally-occurring soil bacteria, Saccharopolyspora spinosa. Once absorbed or ingested by target insects, spinosad causes prolonged involuntary muscle contractions and tremors, resulting in neuromuscular fatigue, paralysis and death. Spinosad has a high level of activity against a number of insect species, including the sheep body louse (Bovicola ovis). Its unique mode of action controls lice strains that are resistant to insect growth regulator (IGR) and synthetic pyrethroid (SP) compounds.3

Despite its deadly activity against lice, Extinosad Pour-On poses remarkably little risk to humans, livestock or the environment when used in accordance with the label directions. It can be applied safely to all classes of sheep, including lambs.

Ideal for off-shears

Extinosad Pour-On is ideal for off-shears lice control. Its unique mode of action kills lice within hours and provides a much-needed alternative to insect growth regulator (IGR) compounds, to which resistance has been identified.(1) In four large-scale trials involving Merino wethers, ewes and rams, lice were undetectable in sheep five months after treatment with Extinosad Pour-On off-shears.(2)

Ideal for long wool

Extinosad Pour-On is the most effective pour-on treatment available to kill lice in sheep with long wool. (2) It kills lice within hours, including those strains resistant to synthetic pyrethroid (SP) compounds (e.g. Vanquish†) and has no wool or meat withholding periods. Extinosad Pour-On delivers excellent control of lice in sheep with long wool. Seven Australian field trials found Extinosad Pour-On reduced lice numbers in long wool sheep by an average of 97.3% two months after treatment!

Application guidelines

Apply using the special manual applicator or a powered applicator fitted with a modified t-bar nozzle. Halve the dose volume and apply as two bands approximately 5 cm from the backline on each side of the animal. Apply each band evenly from the poll to the base of the tail. Confine treated sheep in the yards for a short time to improve the spread of Extinosad Pour-On around the body via rubbing and/or physical contact with other sheep.

Always read the label instructions before use


Getting the best results

·         Treat all sheep on the property at the same time.

·         Muster each paddock thoroughly to ensure all sheep are treated.

·         Check boundary fences to ensure treated sheep are contained and to prevent untreated             or lice-infested sheep from joining treated mobs.

·         Do not mix treated sheep with untreated sheep, infested sheep or those of unknown lice           status.

·         Do not use on sheep with lumpy wool.

·         Sheep that require treatment with a long wool lousicide should be re-treated after                     shearing.

·         Moderate rainfall occurring after treatment will not adversely affect lice control provided           by Extinosad Pour-On.
