In late October, the U.S. Environmental Protection Agency announced a favorable re-registration for atrazine, which paves the way for its continued use by no-tillers. “This decision confirms what extensive scientific studies have shown — that atrazine meets the most stringent regulatory safety standards,’ says Mike Mack, president of Syngenta Crop Protection, an atrazine producer.

With fewer new herbicides coming on the market each year, no-tillers are paying much closer attention to developing more effective weed-management plans. As a result, no-tillers are intently studying how various herbicide and tankmix combinations perform in their fields.
