Rob’s Report by Robbie Smith
Seed head structures
Recently I have taken a lot of calls and visits on a very nasty weed that has come into our county. We are accustomed to Red Root Pigweed and Smooth Pigweed but a couple of new monsters are grabbing acreage and taking away options for control due to their resistance to traditional chemical options. Palmer Amaranth and Common Waterhemp are both in the pig weed family and have been causing problems in the Midwest and South for a number of years but only recently has taken hold in our area.

There are several characteristics that differentiate the three amaranth species:
The presence of hair
Leaf shape
Petiole length
Apical meristem growth pattern
Understanding these characteristics will help you correctly identify amaranth species, and then determine the proper management strategies. This is a weed that should not be taken lightly. It’s impact on yield and profit will be felt. I can see these weeds poking their heads up in fields right now and efforts should be made to get rid of them now. Be a good neighbor and scout now to rid this plant. Some really good information can be found at the following links. https://www.youtube.com/watch? v=I44_-g7nans&feature=youtu.be https:// www.extension.purdue.edu/ extmedia/ws/ws-51-w.pdf
