Editors have highlighted the following attributes while ensuring the content's credibility: Two-thirds of Americans favor banning the use of the herbicide glyphosate, the active ingredient in the popular weedkiller Roundup, on crops grown in the United States, according to a nationally representative survey conducted by the Annenberg Public Policy Center (APPC) of the University of Pennsylvania. Yet the spring survey also finds that most Americans have read, seen or heard little about glyphosate in the few months preceding the survey, and many are uncertain about its health effects.
Support for banning glyphosate cuts across political and ideological groups, the survey finds. Seventy-two percent of people who identify as supporters of the MAHA movement, or Make America Healthy Again, favor banning glyphosate, as do 70% of those who do not support MAHA. Support for banning the herbicide is also strong among both major parties: 70% of self-identified Republicans and 69% of self-identified Democrats favor a ban.
Fewer self-identified independents favor a ban. "Americans express strong support for banning glyphosate even though most acknowledge hearing relatively little about the herbicide in recent months," said Ken Winneg, APPC's managing director of survey research. The findings come from Wave 29 of the Annenberg Science and Public Health (ASAPH) survey, which was conducted April 14–28, 2026, among 1,639 empaneled U.S. adults.
MAHA support was assessed by asking whether survey respondents consider themselves supporters of the Make America Healthy Again (MAHA) movement. Those who report being MAHA supporters comprise 26% of survey respondents. Those who do not support MAHA make up 40% of survey respondents, while those who are not sure comprise 33% of respondents.
See the end of this release or the topline for further details. The weedkiller Roundup, which contains glyphosate, has been used in the United States since the 1970s. MAHA activists and influencers have called for banning or permanently phasing out the use of glyphosate on crops in the United States.
Zen Honeycutt, the founder and executive director of Moms Across America, which supports MAHA, said at a People vs. Poison rally in April 2026, "For 14 years, I have dedicated my life to getting glyphosate banned and transforming our food supply." MAHA health activist Kelly Ryerson, who goes by the online moniker Glyphosate Girl, argued in comments to the for "a permanent phase-out of glyphosate and glyphosate-based herbicides, including on our agricultural land." Health and Human Services Secretary Robert F. Kennedy Jr. has long said that glyphosate causes cancer but has not advocated for an outright ban.
