    • ‘Defoliation by lepidoptera can induce cyanogenesis in some plants resulting in cyanide levels high enough to kill cattle.’
    • ‘The findings from this project may also ultimately be useful for controlling cyanogenesis in cassava.’
    • ‘However, early growth of S. litura larva was reduced 36% on Huia plants, and this was attributed to the greater cyanogenesis.’
    • ‘For many years I have been interested in the ecological genetics of cyanogenesis in plants.’
