For the protection of mulesing and marking wounds on sheep against fly strike caused by dicyclanil-susceptible strains of blowflies (Lucilia cuprina) during the wound healing process.
DIRECTIONS FOR USE
CLiK™ Extra can be applied to all breeds of sheep, either off-shears or with any length wool. Apply CLiK Extra according to the label directions. Apply as a low volume treatment onto areas where protection is required. The nozzle of the applicator gun should be positioned about 15–25 cm above the fleece to achieve a 15 cm wide band at each pass for protection from body strike.

MANAGEMENT CONSIDERATIONS
Australian trials have shown CLiK Extra protects sheep against body, breech and poll strike for up to 29 weeks. However, the length of protection may be reduced by:
- Application during gusty or windy conditions
- Heavy rain following application

- Presence of dermatophilosis
- Significant soiling with dags, mud, dust or urine
-
TREATMENT OF EXISTING STRIKE
CLiK Extra, CLiK Spray-On and CLiKZiN Spray-On are not recommended for treating existing strikes. Use a product that is registered as a dressing for existing flystrike (e.g. Extinosad™ Eliminator).

FOR EXTRA PEACE OF MIND
CLiK Extra gives you extra peace of mind that your sheep, either off-shears or with any length wool, have the longest protection available against flystrike, particularly with unpredictable fly seasons.
Refer to registered label for full information. Apply in accordance with label directions. Incorrect application, spray drift, soiling of wool or heavy rain following the application of these products could diminish the period of protection. Where significant dags are present, a light crutching is indicated prior to treatment. Reduced efficacy may occur in sheep affected with dermatophilosis. Do not apply at the same time as any other backline product. Do not dilute or mix with any other product. These products are not recommended for treating existing strikes.
