Question of the Week: Pigweed

Last week the question was:  What are the weeds surrounding these young cotton plants?

This was an easy one.  These is pigweed, Palmer amaranth to be more specific.  There is not a single farmer in SC that hasn’t fought pigweed.  This is one of the most serious and frustrating weeds we deal with because resistance to several different herbicide modes of action have been found.  Take a look at the 2017 SC Pest Management Handbook for control recommendations in various crops.

 

Here is this week’s question:  What made this nearly perfect circle in this leaf?
