German Agriculture Minister Julia Kloeckner on Tuesday said she was finalizing a draft regulation to end use of the weed-killer glyphosate in household gardens, parks and sports facilities, and to set “massive” limits for its use in agriculture.

The chemical, made by Monsanto, is at the center of a heated debate in Europe over whether it causes cancer.

Chancellor Angela Merkel’s conservatives and the centre-left Social Democrats (SPD) agreed in February to systematically and significantly limit its use, with the goal of entirely ending use of products that contain it, but set no timeframe.

“I am planning a regulatory draft as a first building block in the strategy to minimize use of glyphosate,” said Kloeckner, a member of Merkel’s Christian Democrats (CDU). She said the proposal would be vetted by other ministries, but set no deadline for when Germany would end use of the weed-killer.
