Definition of parasiticide in US English:



  • A substance used in medicine and veterinary medicine to kill parasites (especially those other than bacteria or fungi).

    • ‘Wormers accounted for 26% of the market, biologicals for 20% and external parasiticides for 10%.’
    • ‘We don't use any commercial fertilizers, herbicides, insecticides, parasiticides, antibiotics, or growth hormones.’
    • ‘One of the most effective treatments is a parasiticide that is applied to a small area at the back of the neck.’
    • ‘‘This means,’ says Gasbarre, ‘that growers can reduce their use of parasiticides by removing or treating the few high-parasite animals once they're identified.’’
    • ‘Arsenic compounds, commonly used in non-organic poultry feed as growth promoters and parasiticides, are linked to high incidence of cancer and other illnesses in areas where poultry litter containing arsenic is used as fertilizer.’
