Ségolène Royal, France’s minister of ecology, sustainable development and energy, has called for a ban on glyphosate mixed with certain adjuvants (additives) due to its perceived risks to human health.

On Feb. 12, Royal called for ANSES—France’s food, environment and health agency—to withdraw authorizations on herbicides containing glyphosate mixed with the adjuvant tallow amine, according to French newspaper Le Monde (via Google translate).

Although it wasn’t explicitly said, one can only conclude that this measure was directly targeted at Monsanto and other herbicide makers.

Tallow amine, or polyethoxylated tallow amine, aids the effectiveness of herbicides such as glyphosate. The chemical is contained in Monsanto’s widely popular weedkiller Roundup, according to the Northwest Coalition for Alternatives to Pesticides, which published a letter from Monsanto listing the ingredients. Roundup’s ingredients are as follows:

- Isopropylamine salt of glyphosate (active ingredient)

- Water

- The ethoxylated tallow amine surfactant

- Related organic acids of glyphosate

- Excess isopropylamine
