    Whether Or Not Roundup Is Safe The Gardener Has Better Options

    This story has been updated.

    Unless you have been living on Mars, you have probably seen the TV ads from law firms seeking cancer patients who have used the ubiquitous herbicide brand Roundup.

    Three recent high-profile cases in California have brought verdicts against Roundups maker, Monsanto, one with a jury award of $2 billion, later reduced to $86.7 million. Bayer in 2020 agreed to pay almost $11 billion to settle some 100,000 lawsuits, without admitting liability.

    Monsanto insists Roundup is not carcinogenic, says it has no plans to pull it from the market and is appealing the verdicts. Its clear these products are safe when used as directed, said Rakesh Kilaru, a Washington attorney for Monsanto.

    Much of Monsantos legal morass stems from a 2015 report from the World Health Organizations International Agency for Research on Cancer that said Roundups active ingredient, glyphosate, was probably carcinogenic. More recently, researchers at the University of Washington looked at available data and concluded that Roundup could increase the risk of developing non-Hodgkins lymphoma by 41 percent.

    In addition, the long-term Agricultural Health Study of more than 52,000 pesticide applicators, conducted by the National Cancer Institute and others, reported a link between cancers and some pesticides, but not glyphosate.
