Bayer and Weed Control

I have done a number of stories recently about weeds and glyphosate resistance. It appears that it is just a matter of time before glyphosate based herbicides become virtually ineffective. I was attending a Bayer Crop Science symposium and ran into the Product manager for corn herbicides Christov Breitenstroter. "Controlling weeds through canopy, what does that mean? It just points out the importance of making sure that you stay weed free until canopy. The effects that we see from having weeds can be quite detrimental. You are looking at yield loss that can be quite substantial. Iowa State University did a study that found that 3 to 4 inch weeds can actually take away 3 bushels per acre for every day that those weeds go uncontrolled. You want to control weeds early so don't let them grow and the other thing is that you make sure you stay weed free, especially when you have issues with some of the late emerging weeds like Palmer amaranth and water hemp. I have heard that weeds are increasingly resistant to glyphosate. What is Bayer doing to combat that? What we recommend and what we have in our portfolio is products that contain multiple and effective modes of action. The problem humanely have is with glyphosate resistance and we are recommending using alternative modes of action.
