On Wednesday, February 15, Muthu Bagavathiannan, specialist in weed ecology and agronomy, presented a new tool for consultants, extension specialists and agents, and growers to assist with management decisions regarding Palmer amaranth, named PAM. Based in Microsoft Excel, the tool allows the user to input their rotation schedule, chosen varieties and other management practices. From those entries, the tool calculates the amount of weed seed present over a 10-year period, as well as the economic gains or losses during that period. In addition, it calculates the risk of the combination of practices and allows the user to compare up to 6 different management scenarios. The tool calculates risk based on the amount of weed seed present, which has been concluded to be the main reason for pigweed-related crop failures.
You can get to the tool from 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
