Stabilised Formulation - Improved efficacy and lower tox


The novel patented Fyfanan EW formulation preserves the malathion active ingredient with only very limited formation of toxic iso-malathion and other degradation products such as mercaptanes and disulphids.


The information below shows that the acute toxicity (e.g Rat) of malathion is more than 40x less toxic than the degraded isomalathion


  • Acute LD50 oral (rat) Malathion  >5000 mg/kg bw

  • Acute LD50 oral (rat) Iso-malathion rat >113 mg/kg bw


Fyfanon EW is positioned under the WHO classification system as 'U' i.e Unlikely to present acute hazard in normal use. Additionally reduced use of organic solvents further reduces the impact on the environment
