Roundup causes high levels of mortality following contact exposure in bumble bees

Journal of Applied Ecology, Volume 58, Issue 6, Page 1167-1176, June 2021., 2021
Surfactants, or other co‐formulants, in herbicides and other pesticides may contribute to global bee declines. We recommend that, as a precautionary measure until co‐formulant identities are made public, label guidelines for all pesticides be altered to explicitly prohibit application to plants when bees are likely to be foraging on them.
