Synergized PYthon Dust is the most significant
livestock dust innovation in 20 years. It is the only
dust to contain two novel active ingredients for
maximum efficacy against all major livestock
ectoparasites. Zetacypermethrin is a 4th generation
pyrethroid, single-isomer insecticide with enhanced
potency against resistant horn fly strains. The
photostable form of piperonyl butoxide is a mixedfunction
oxidase inhibitor that reduces metabolic
resistance in insects, thus synergizing the pyrethroid
for maximum efficacy and residual activity.
