Many practices in cotton, including the use of spray hoods, fell by the wayside with the advent of Roundup Ready technology.  Enter glyphosate-resistant Palmer pigweed, the arch nemesis of cotton production, and producers are realizing practices from the past may help sustain agriculture for the future.The recently introduced 915 Gramoxone ...

  For several years now, weed scientists and industry experts have been warning producers about glyphosate resistance.  For many years those warnings were not always acted upon.  But now, approximately six years later, the tide seems to be turning and more and more producers are fighting resistance with everything they can ...

As growers across the Delta fight glyphosate-resistant Palmer pigweed, it's encouraging to hear the stories of guys who've managed it successfully.  A grower in Blytheville, Ark., noticed suspicious Palmer pigweed in his fields last season.  Rather than stick with his typical weed control program, he heeded the advice of one of ...

At a recent field tour, University of Arkansas weed scientists Ken Smith and Bob Scott walked attendees through trials on a Widener, Ark., farm that had become a Palmer jungle last season.  To the surprise of some, both researchers said it is possible to successfully manage the problem, both in Roundup Ready® and LibertyLink® ...

Glyphosate-resistant Palmer pigweed has become the most damaging weed we've seen to date on crops in the South. Researchers at the Southern Weed Science Society (SWSS) Meeting last week in Little Rock, Ark. reported 1.6 million acres of cotton and soybeans are currently affected by glyphosate-resistant Palmer pigweed. As a result, hand-weeding ...

Recently, experts in the glyphosate arena discovered a new mechanism of resistance by which plants thwart herbicide applications. Southeast Farm Press reported on these findings and its impact on the rapid spread of glyphosate-resistant Palmer pigweed. Pollen from pigweed plants can easily travel 300 to 400 feet in a cropping season. ...

I've been encouraged as I've talked to producers this fall.  Many are making plans to incorporate residual herbicides into their weed management programs for 2010.  Yet, as the adage goes, old habits die hard for some growers who continue to rely on glyphosate alone.  For those who have recognized the need for a residual, ...

In the ABC news segment, “Super Weed Can’t Be Killed,” that aired earlier this week (October 6, 2009), you may have seen news correspondent Steve Osunsami’s reporting that Palmer pigweed can no longer be controlled.  It is true that this weed has become a formidable foe for producers across the South, but to ...
