Tomorrow at 3 PM ET: Learn about a pigweed decision management tool

Herbicide resistance in Palmer amaranth (known as Palmer pigweed) is a serious issue in the Southern US and is spreading to several other states. Repeated use of a few herbicide mechanisms of action (MOA) without sufficient management diversity is the common cause of this resistance. A proactive resistance management strategy that integrates diverse chemical and non-chemical tools will help prevent/manage resistance and preserve the utility of available herbicide options.

This webinar provides a general overview and demonstration of a new Microsoft-Excel based decision support tool that guides informed decision making for effective management of this weed, with particular focus on soil seedbank management and profitability. Users can build their own management programs and see for themselves how effective their pigweed management program is, as well as overall economic outcomes associated with their options. This tool also predicts the likely risk of resistance for the management program built by the user.

New software to control pigweeds

NOTE: One of the PDs on this project, Muthu Bagavathiannan, will be conducting a webinar on use of this software next Wednesday, February 15, at 3 PM Eastern time. To find out more information, or to register, click this link.

As Mid-South pigweeds continue to be stubborn and hard to control, methods to combat them are expanding. In mid-January, the University of Arkansas released a software package (http://bit.ly/2kBMIwn) to assist growers in making informed decisions managing Palmer amaranth.

“It’s a unique software tool in that you can select whether you have glyphosate resistance, ALS resistance, or PPO resistance,” says Jason Norsworthy, weed scientist.  “From there, you devise potential herbicide management strategies over a 10-year period. We’re very proud of the program.” Continue reading
