E.Central MN | Some guys have been doing that year after year. I have done that for 2 years, but only one field has been r/u corn two years in a row. Many put a non-glyphosate product down pre-plant and some mix other products with the glyphosate post-emerge on corn. I am seriously looking at going back to conventional corn next year although a few neighbors have used Liberty corn for several years in a corn/bean rotation. Last year they had a lot of weed problems. It rained hard after they sprayed and then turned very dry. Weeds germinated and really hurt the yield when moisture got short. | |

How many useful years does Roundup have left?
