Bayer books second-quarter loss after settlement

Frankfurt | Reuters — German drugs and pesticides group Bayer reported a 9.5 billion-euro (C$14.86 billion) net loss for its second quarter, following a US$10.9 billion settlement of U.S. lawsuits claiming that its Roundup herbicide caused cancer.

Weather conditions that can volatilize dicamba herbicide

Avoid applying all herbicides during temperature inversions too

In addition to drift caused by wind the herbicide dicamba can end up off target due to volatilization, also referred to as vapour drift, and temperature inversions. Last week’s stories on dicamba (see ‘Related Articles’ below) prompted a reader to ask about the weather conditions for both. The University Minnesota explains it on its website

Canadian, U.S. farmers diverge on dicamba spray issues

While U.S. farmers have been devastated by dicamba drift, it’s been a non-issue in Canada

Canadian farmers haven’t experienced the same dicamba drift debacle their U.S. neighbours have — but that doesn’t mean they won’t also pay a price for this high-profile failure.

Dicamba spray drift declining in Canada

The climate and how the herbicide is used here both are factors

Bayer to pay up to US$12 billion to resolve ag chem, PCB claims; company is "not contemplating" a Canadian glyphosate settlement

Bayer scraps plans for U.S. dicamba production

Move unrelated to court ruling, company says

Chicago | Reuters — Bayer said on Tuesday it will scrap a nearly US$1 billion project to produce dicamba in the United States, but said the move is unrelated to a federal court decision that blocked sales of dicamba-based herbicides.
