Summary

Story summary

Supreme Court heard Bayer’s appeal of a Missouri verdict awarding $1.25 million and will decide by 2026.
Conservative justices pushed for a federal pesticide label while liberal justices urged deference to state actions.
Bayer argues the Insecticide, Fungicide, and Rodenticide Act preempts claims because EPA has not required a cancer warning.
Agricultural groups warned that forcing Bayer to add cancer warnings could threaten production, leading to protests outside the Court.

History

Historical Context

EPA’s 1972 ban on DDT—first major pesticide restriction after Rachel Carson’s 1962 Silent Spring—forced Monsanto’s DDT line off U.S. markets, cutting roughly 2.5 million pounds of annual use. The decision anchored federal authority over pesticide labeling, a precedent now tested as Bayer, Monsanto’s successor, faces a Missouri Supreme Court appeal over a $1.25 million verdict that could cement nationwide preemption.
