Fungicide resistance is a relatively new concern for corn and soybean farmers. But like resistance to herbicides, the problem starts small in just a few counties or a state, and the resistant pathogens spread. Like herbicide resistance, the cause is overuse of fungicides with the same mode of action.
As resistance to glyphosate and other herbicides continues to develop across North America, raising grower awareness of the problem is of primary importance. With no new herbicides on the horizon with the one-size-fits-all mentality of glyphosate, it’s important to preserve the tools we have.
