The Supreme Court handed Bayer a massive win last week in its attempts to beat back lawsuits alleging its Roundup weedkiller causes cancer. Now, the German company is separating Roundup into its own business.

Bayer plans to shift its U.S. glyphosate business-which produces Roundup-into a subsidiary, Ruveon. It will assume responsibility for pricing, production and logistics for supplying American farmers.

Glyphosate is the most popular herbicide on the planet, and Bayer makes more than 40% of the world's supply, generating around $3 billion in annual sales. The rest comes from China.

Bayer earlier this week filed a federal anti-dumping petition against generic Chinese glyphosate products, requesting tariffs. That would raise prices for imported glyphosate, and has angered U.S. corn farmers who had backed Bayer in its glyphosate litigation.
