The Take Action program is a collaborative effort between the United Soybean Board, 15 land-grant universities, and several agricultural-technology companies.  The purpose of the program is to produce new educational materials an effort to help farmers prevent and manage herbicide-resistant weeds. The following newly released bulletins have been cross-posted to MSUweeds.com.

 

 

 

 

 

Palmer amaranth management in soybean, corn and alfalfa–New bulletin

Monday, November 18th, 2013

Just last week Dr. Christy Sprague published a new extension bulletin titled “Multiple herbicide-resistant Palmer amaranth in Michigan: Keys to management in soybean, corn and alfalfa.” This bulletin reflects our research findings after studying Palmer amaranth the past 3 summers in Michigan. In addition to being available on MSUweeds.com, this bulletin will also be included at the end of the 2014 Weed Control Guide for Field Crops (E-434). Click on the image below to view the bulletin.

Dr. Christy Sprague recently completed a 2 year study on the control of windgrass in winter wheat. As a result of this study she has produced a new extension bulletin with common windgrass information on properly identifying the weed and keys to successful management. You can find the new bulletin at MSUweeds.com in the Extension Publications section or by clicking on the image below.

Taking my work home with me?!

After a day of working in our research plots in the fall I often find weed seeds in my pockets, shoes, and even in my hair. Today we were pulling our final Palmer amaranth plants from two of our studies in Middleville, MI, where we have been studying the growth and development and potential control options for this weed. At this time of year many weeds are already bearing mature seeds, and Palmer is no exception. Because Palmer amaranth is still relatively new to Michigan and because it is both glyphosate and ALS resistant, we are always careful to ensure that we do not transport seeds from these previously infested sites to other locations by cleaning of our trucks and equipment and cleaning of our shoes. Out of curiosity today I decided to count just how many seeds I found inside of my shoes after working in the plots for around 2 hours. I ended up with 25 seeds, plus I probably had a few more I had already dumped out of my pockets before counting. I think this is a good reminder to everyone that we are just as likely to be transporting seeds as are animals and equipment.

Just this week we finished production on our Palmer amaranth identification video. We hope that this will be the first of a series of videos helping to identify and manage this herbicide-resistant weed in Michigan.
