Active Ingredients: ABAMECTIN @ 80g/kg & PIPERONYL BUTOXIDE @ 180g/kg
One Tag per each ear of each animal (2/head).
AGRESSOR is a plastic ear tag containing a synergised formulation of abamectin (avermectins B1a and B1b) and piperonyl butoxide. Abamectin is a highly active macrocyclic lactone that has never been used before in an ear tag in Australia.
The formulation contains a high loading of piperonyl butoxide which synergizes the abamectin for maximum pesticidal action. This insecticide has excellent activity against strains of Buffalo Fly known to be resistant to other chemical compounds like organophosphates and synthetic pyrethroids.
This allows for the first time, an annual three way insecticidal rotation program to be adopted to reduce the impact of insecticide resistance.
The AGRESSOR tag has a net weight of 9 grams and a metallic gold colour.
Controls susceptible buffalo flies for up to 12 weeks in Beef Cattle.
AGRESSOR is available in 20 and 100 tag packs, in sachets of 20 tags each. Each tag contains a male button for attachment.
  • Agressor contains a unique chemical compound making it ideal for use as a third rotation option in the Insecticidal tag rotation program with organophosphates (OPtimizer and WARRIOR) and synthetic pyrethriods (PYthon and PYthon MAXIMA) to minimise Buffalo Fly insecticide resistance.
  • Agressor is the only ear tag worldwide to contain a macrocyclic lactone, which has excellent pesticidal activity against OP and SP resistant strains of Buffalo Fly.
  • Agressor provides control of Buffalo Fly for up to 12 weeks, reducing the need for frequent re-treatments and mustering costs.
  • Works very rapidly, usually eliminating Buffalo Flies within 1 day.
  • Agressor is the only synergised Abamectin tag worldwide, designed for extended release of active ingredients.
  • The tag has no objectionable odour.
  • Rainfast - Agressor was proven effective in field studies in North Queensland where rainfall in excess of 1,000mm was recorded over the four month trial period.
  • Provides sustained pest control potency that can result in increased weight gains.
  • Nil withholding period in meat of Beef Cattle.
  • Has patented Snap-Lok collar for guaranteed retention against tag or button failure for 5 months.
  • Uses the proven two-piece application system.
Agressor Tags are contraindicated for use in calves less than 16 weeks of age or less than 50kg bodyweight.
Animal: Beef and Dairy Cattle (including lactating dairy cattle)

State: All States and Territories
Rate: Two Tags per animal (1 in each ear)
Critical Comments: Apply only when fly numbers exceed acceptable levels.  Two tags should be applied per animal (1 in each ear).  Removal of tags after 12 weeks will ensure that Buffalo Fly Populations are not exposed to sublethal doses which may increase the chance of resistance.  Remove tags with tag removal knife.  The level and duration of control may be reduced under high fly pressure.  The whole herd is to be treated concurrently. Remove tags prior to slaughter.
