Rising insecticide potency outweighs falling application rate to make US farmland increasingly hazardous to insects

M. R. Douglas, D. B. Sponsler, E. V. Lonsdorf, C. M. Grozinger

The paper estimates insect toxic load from US agricultural insecticides between 1997-2012, finding a 9-fold increase in oral toxicity despite reduced application volumes, driven by higher potency and expanded use areas.
