\nSteckle said we\u2019ve now reached the point where we have to begin thinking in terms of controlling \u201cresistant weeds\u201d instead of \u201cresistant marestail\u201d or \u201cresistant Palmer pigweed\u201d because they are both beginning to show up in the same field.\n

\n\u201cWe have to manage them both,\u201d he said. \u201cThere\u2019s a new product from BASF called Sharpen that I\u2019ve been looking at for five years and I\u2019ve been very impressed with the marestail control. I still like dicamba, Roundup and Gramoxone.\n

\n\u201cBut if you have Palmer pigweed, too, then you\u2019re going to have to overlap with residuals \u2015 Cotoran, Caparol, Prowl \u2015 to have any chance to do a good job of controlling them.\u201d\n<\/blockquote>\nSo, what’s the solution:\n\n\n

\nResistance to one herbicide or others across the Cotton Belt ranges from a high of 18 in California to none in Arizona. The Mid-South states average the highest.\n

\nThe most troublesome weed by far is Palmer amaranth, followed by marestail.\n

\nGeorgia Extension weed scientist Dr. Stanley Culpepper said he\u2019s fought it long enough to realize that the best control of resistant Palmer amaranth is to keep it from ever germinating.\n

\n\u201cIf you have dryland production in the Southeast, Mid-South and the Mid-Atlantic states and think you can go in with 50-something-dollar herbicides and control resistant Palmer amaranth without rain, you will lose,\u201d he said. \u201cIf we integrate them with programs that deep-turn the land, we can reduce the amount of Palmer amaranth seed that emerges by 50%, and that greatly improves control. Conservation tillage growers can also do that by using a rye cover crop to reduce emergence.\n

\n\u201cThe goal is, if it doesn\u2019t come up, you don\u2019t have to kill it.\u201d\n

\nCulpepper said when cover crops and deep tillage have been used together, resistant Palmer amaranth control has been improved by 90% in Roundup Ready programs.\n<\/blockquote>\nNinety percent?\nSo pesticides only do 10%?\nWhy pay for them, then?\n

\nThis recommendation for plowing isn’t just a few researchers’ opinion.\nHere’s where they presented:\n

\nFor the last three years, the Beltwide has kicked off with the Consultants Conference, sponsored by Syngenta, Bayer CropScience and Dow AgroSciences.\n<\/blockquote>\nOne name is conspicuously missing there:\nMonsanto.\nLooks like the other pesticide companies are looking to horn in on Monsanto’s\nRoundup turf.\nBut they only way they’ve found that works is to plow that turf.\n
