This is reprinted from Delta Farm Press, written by Ford Baldwin. It’s a great case about why IPM should be used for weeds. Read the story at Delta Farm Press.
I just returned from the Global Herbicide Resistance Challenge conference in Fremantle, Australia. It was a great meeting with a lot of internationally renowned weed scientists making excellent presentations. It was essentially the “State of the Union” on where we are on herbicide resistance world-wide.
Kentucky farmers have battled weeds resistant to herbicides containing glyphosate for the past decade. A recent survey of agriculture and natural resource agents with the University of Kentucky Cooperative Extension Service indicates these weeds are becoming more widespread.
2,4-D is coming back. What many might consider a “dinosaur” may be the best solution for growers fighting weed resistance today, says Dean Riechers, University of Illinois associate professor of weed physiology. “Farmers can’t imagine going back to 2,4-D or other auxin herbicides,” Riechers says. “But herbicide resistance is bad enough that companies are willing to bring it back. That illustrates how severe this problem is.”
