NEW Extension Bulletin: Keys to distinguishing Palmer amaranth from other species

Wednesday, March 27th, 2013

-E. Taylor

Today we just posted an extension bulletin to MSUweeds.com to help distinguish among the pigweed species currently found in Michigan. Species we currently have include:

  • Powell amaranth
  • Redroot pigweed
  • Smooth pigweed
  • Palmer amaranth
  • Waterhemp

Some of these species in Michigan have been confirmed to be resistant to different herbicides (e.g. glyphosate and ALS inhibitors), so confirming the identity of your weed may be critical to the strategies needed for control.

Check out “Keys to distinguishing Palmer amaranth from other species” at MSUweeds.com.

MSU 2013 WSSA posters available

Thursday, February 7th, 2013

-E. Taylor-Hill

We just returned from Baltimore, MD (home of the 2013 Superbowl Champions) where we attended the 2013 Weed Science Society of America annual meeting. It was a great opportunity to look at weed related research from around the nation and beyond and to take a look at how the rise in herbicide resistant weeds seems to be impacting agriculture across the U.S. (look for a future blog on that).

Now that we are back I posted the 3 posters that we presented. Our topics included…

  • Influence of soil amendments on seed mortality of herbicide resistant Palmer amaranth
  • Volunteer glyphosate resistant (RR) corn control in RR sugarbeets
  • Cover crop influence on weed pressure in organic dry beans

Visit the Presented Research section to view the posters.

Windgrass control in wheat

PRE treatment application for windgrass control in wheat

PRE treatment application for windgrass control in wheat

Yesterday Christy Sprague and I traveled up into the thumb to Minden City, MI. Here we have a plot with a grower cooperator looking at windgrass (Apera spica-venti) control in winter wheat. Windgrass is a winter annual grass, so its growing season corresponds well to the wheat season. Today we applied four preemergence treatments and we will return to the sight when the windgrass is ~1″ tall to apply several post-emergence treatments. This will be the second year of this study. The results from the 2011-2012 season can be found on here on MSUweeds.com
