As a result, farmers were unable to spray dicamba on crops this year. The EPA has received applications from Bayer (OTC: BAYRY ) AG, BASF (DE: BASFn ) and Syngenta for new approvals, the agency said in regulatory documents. Bayer, which sold the dicamba herbicide XtendiMax, said it was pleased the EPA opened a public comment period on its proposal to approve dicamba usage. "We are confident that low-volatility dicamba herbicides, when used according to the label, can be used safely and successfully on-target," Bayer said. BASF said it would work with regulators to ensure farmers can use dicamba. Syngenta did not immediately respond to a request for comment. An EPA review found no risk to human health from the products, but some risk to certain plants, it said in a release. To mitigate that risk, the agency is proposing restrictions on how much of the chemical can be applied and when, the release said.
