Safer for YOU, Kinder on your stock

Redact has been formulated to be extremely efficacious in the control of flies, lice and ticks on cattle and horses. Redact differs from other products in the delivery of its chemistry. We’ve gone away from using solvent based products to administer that chemistry. Redact is a water concentrate (WC) product utilising modern chemistry.

Redact is a new generation water based microemulsion formulation containing 200g/L Cypermethrin in the form of an emulsion. Unlike other available Cypermethrin products, Redact contains no Xylene and is non-flammable, reducing the risk to users and animals when handling the product and may be applied through spray races or by hand spraying. The WC formulation, with Zeta sized particles for more contact and faster uptake, achieves up to 40% less spray drift than comparable EC formulations.

Redact contains no Xylene, has a lower odour profile and is kinder on equipment and surfaces – making it much safer for not only the treated animals but the applicator and environment as well.

The photos below show the impact flies can have on calves/Cows and then shows application of redact and then the same calf after application.

Safer for YOU, Kinder on your horse

Flies are a big problem for horses out in the paddock, in the stable and when travelling in horse floats and trucks.

Redact is a new product that provides a “kinder” chemistry offering you a safer and friendlier alternative than current market products. 1L of this concentrated product goes a long way. Just add 5ml into a 1L spray bottle and spray directly on your horse’s legs and body or spray onto the walls in your stables, floats and trucks to repel flies.

Please read application instructions prior to using.
