Roundup (glyphosate) is in wide use in Europe.

Not to the same extent apparently because of GMO.

One category of GMO is called “Roundup ready”

It means crops that can take Roundup and survive at high concentrations of glyphosate while natural crops have some limit of concentration. That means higher usage in the US.

"Glyphosate has been assessed 3 times in the EU. The first assessment resulted in initial approval of glyphosate in the EU in July 2002. The second assessment, which was carried out between 2012 and 2017, led to the first renewal of approval.

The most recent assessment was carried out between 2019 and 2023 by Member State Competent Authorities, the European Food Safety Authority (EFSA) and the European Chemicals Agency (ECHA), and showed that there is currently no scientific or legal justification for a ban. This led to the renewal of approval of glyphosate in 2023.

Under the conditions of approval and by following good agricultural practices, glyphosate is considered not to pose any harmful effects on human health or unacceptable effects on the environment."

If you keep digging you’ll find some countries have banned it.

And because Roundup ready GMO are not in use, the usage is lower in the EU vs US.
