Two-thirds of Americans favor banning glyphosate, the active ingredient in the weedkiller Roundup, on crops grown in the United States, according to a nationally representative survey by the Annenberg Public Policy Center (APPC) of the University of Pennsylvania.
Support for a ban cuts across political lines, the survey found. Seventy percent of self-identified Republicans and 69% of self-identified Democrats favor banning the herbicide. Seventy-two percent of those who identify as supporters of the Make America Healthy Again (MAHA) movement favor a ban, as do 70% of those who do not support MAHA.
Despite strong backing for a ban, most Americans have read, seen or heard little about glyphosate in recent months, the survey noted. More than eight in ten respondents reported exposure to either "nothing at all" or "a little" information about the herbicide. Ken Winneg, APPC's managing director of survey research, said that "Americans express strong support for banning glyphosate even though most acknowledge hearing relatively little about the herbicide in recent months."
The findings come from the Annenberg Science and Public Health (ASAPH) survey, conducted April 14–28, 2026, among 1,639 U.S. adults. Half of American adults believe exposure to glyphosate causes cancer, while 46% are not sure and only 4% say it has no effect on cancer risk.
Health and Human Services Secretary Robert F. Kennedy Jr. has previously said that glyphosate causes cancer but has not called for an outright ban. In February 2026, President Donald Trump signed an executive order protecting domestic glyphosate-based herbicide production, citing military readiness and agricultural strength. The order prompted criticism from MAHA activists. Kennedy later defended the order but reiterated concerns about glyphosate in food, saying a sudden ban "would destroy the American food system."
