How Concerned Should We Be About Fungicide Resistance?


By now, farmers are all too familiar with weed populations developing resistance to herbicides (sometimes more than one). Given what we know and understand about how resistance develops, how concerned should farmers be about diseases becoming resistant to fungicide applications?

Scott Henry, with Bayer, sat down with Shaun Haney to break down this not-so-straight-forward topic. The good news is that fungicide use is actually relatively low in Canada, and usage is one factor in the speed of which resistance develops. That said, there are risks of it happening, and Henry recaps some of the best management practices — like genetic resistance and cultural control practices — farmers should be using to extend the useful life of the fungicide products we have available.
