Table 4 Studies published since February 1, 2015 and the completion of the EPA [3] and IARC [4]  reviews of glyphosate and formulated GBH genotoxicity

From: How did the US EPA and IARC reach diametrically opposed conclusions on the genotoxicity of glyphosate-based herbicides?

  1. aIncludes studies published after 02/01/2015, the publication date of Marques et al. [43], the most recent study cited in IARC [4] or EPA [3]
  2. bNote that since some studies conducted assays on BOTH glyphosate technical and formulated GBHs, the number of studies on glyphosate technical plus formulated GBHs exceeds the total number of new studies
