Registered indications

Extinosad Aerosol for Wounds is registered for the treatment and prevention of blowfly (Lucilia cuprina) strike in mulesing, marking and other wounds of sheep, including strains resistant to organophosphate (OP) compounds.

Proven benefits

Extinosad provides rapid control of maggots and blowflies, even OP-resistant strains. Australian and NZ trials have demonstrated 98.5% of struck Merino sheep and 100% of struck coarse wool (meat breed) sheep recovered completely after treatment with Extinosad.

How Extinosad works

Extinosad contains the active ingredient, spinosad, which is derived from the naturally-occurring soil bacterium, Saccharopolyspora spinosa. Once absorbed or ingested by target insects, spinosad causes prolonged involuntary muscle contractions and tremors, resulting in paralysis and death. Spinosad has a high level of activity against a number of insect species, including the sheep body louse (Bovicola ovis) and the sheep blowfly (Lucilia cuprina) and its larvae. Spinosad is chemically unrelated to any other compound used in the Australian livestock industry.

Application guidelines

  • Shake well before use
  • Clip or shear wool from over and around the wound
  • Apply directly to wound and 25 mm into the surrounding wool
  • Apply until wound and surrounding fleece is wet and “blue”
  • Avoid contact with skin and eyes

Always read the label instructions before use
