MANA extends its Roundup Ready PLUS® residual herbicide agreement with Monsanto

MANA recently announced that it will extend its collaboration agreement with Monsanto for the inclusion of Cotoran 4L, Direx 4L and Pyrimax 3.2L cotton herbicides under the Roundup Ready PLUS Weed Management Solutions platform through 2016.
   
 In 2014, cotton growers will receive a $2 per acre incentive when using Cotoran 4L, Direx 4L and Pyrimax 3.2L following Roundup Ready PLUS recommendations for glyphosate-resistant and tough-to-control weeds. New to the 2014 MANA/Monsanto partnership will be an expanded geography that includes Texas and Arizona. The Roundup Ready PLUS platform will continue to provide options for Southeast and Delta cotton farmers。

Proactive residual herbicide strategies

Specific to resistance management in cotton, experts advise growers to approach every field proactively and use a residual herbicide at the ideal time for peak product performance.
   
Dave Downing, MANA brand leader, said combating resistance requires a systematic approach in overlapping residual herbicide applications with multiple modes of action, starting at pre-plant/pre-emergence, followed by post-emergence through layby.
 
“Today, if a field is infested with glyphosate-resistant pigweed, a cotton crop can’t be successfully grown or harvested without season-long use of residual inputs,” said Downing. “Fortunately, some of the best solutions for weed resistance are readily available in proven, time-tested chemistries, including Cotoran, Direx and Pyrimax.”
  
Cotoran 4L, applied pre-emergence, provides economical control of annual grasses and broadleaf weeds, especially glyphosate-resistant Palmer pigweed. It offers up to two and a half weeks of residual activity and can be tank mixed with other herbicides to broaden control.
  
Direx 4L is the preferred diuron product for Roundup Ready PLUS and one of the best known herbicide performer against glyphosate-resistant Palmer pigweed and marestail (horseweed). Direx 4L can be applied as a pre-plant, pre-emergence or post-directed application from 6-inch cotton to layby. It can deliver up to three and a half weeks of residual activity.
   
Pyrimax 3.2L is a popular glyphosate-resistance management tool with broad flexibility in application methods and timing, which can be used pre-emergence or post-emergence. Pyrimax 3.2L is proven to control a wide spectrum of weeds including Palmer pigweed, and is the preferred tank mix partner with Cotoran 4L to broaden control on fields showing signs of resistance.
   
Common threads of success

Monsanto Roundup Ready PLUS Weed Management Solutions provides effective economical and sustainable weed management options for farmers. Roundup Ready PLUS is built on three key pillars: weed management recommendations, incentives to use herbicides with multiple modes of action and education and training.
 
Monsanto developed roundup Ready PLUS Weed Management Solutions in conjunction with leading academics and industry partners to help farmers improve their weed control, especially on tough-to-manage and glyphosate-resistant weeds. The Roundup Ready PLUS website includes weed management recommendations by crop and by geography, including the use of residual herbicides that provide multiple modes of action for controlling tough weeds, as well as other weed control resources.
