Antimicrobial action
At the concentrations in this product, the efficacy achieved is > log5 (100,000 times) reduction in microbial counts against Gram positive and Gram negative bacteria, as well as fungi, and yeasts, enveloped and non-enveloped viruses, and spores.
Insecticidal action
The insecticidal actions is based upon cypermethrin (a pyrethroid). In the testing phases the indicator species used was Lucilia cuprina, a commonly occurring blow fly species. As soon as the larvae migrate from the test site and within 30 minutes were dead. Other tests on L. cuprina eggs resulted in a 100% kill. The product was equally effective against adult flies resulting in a 77% kill in 15 minutes rising to 100% within 30 minutes. Cypermethrin is a broad spectrum insecticide and is effective against other insects, eg biting flies, fleas, mosquitoes, and ticks.
Residual action
Residual action tests showed the product was 100% effective after 5 days. Field trials demonstrated that the residual action extended well beyond 2 weeks. The product is water soluble and should be re-applied if the animals has been washed or exposed to rain.
Toxicology
Studies were carried out in accordance with the test requirements as specified by the EPA. Oral toxicity (rats) - >2000 to 5000mg/kg - category III, Dermal toxicity (rats) - >5000mg/kg - category III, Dermal irritation (guinea pigs) - very slight erytherma (grade 1) for a few hours but reversible within 24 hrs - category IV, Eye irritation (rabbits) - after 24 hrs contact the cornea and iris showed no reaction - the eyelids and nictating membranes were graded 1 after 1 hour and were reversible after 72 hrs - category IV, Skin sensitization (guinea pigs) - no sensitization, Inhalation toxicity (rats) - LC50>2mg/litre - category IV.
Stability
Repeat efficacy tests and chemical analysis confirm a shelf life of 4 years from the date of manufacture.
