Pokeweed is Poking Up in a Lot of Corn Fields

by Mark VanGessel, Extension Weed Specialist; mjv@udel.edu

I have seen a number of corn fields with pokeweed emerging along field edges or in patches. These areas should be sprayed before the plants are 10 to 12 inches tall and as result may require some spot applications before the whole fields need to be treated for summer annual weeds. In addition to glyphosate, other effective postemergence treatments include Callisto, NorthStar, Yukon, dicamba (1 pint/A), or Status (5 oz/A). Also note that NorthStar, Yukon and Status all contain dicamba (Banvel) and take precautions so that sensitive plants will not be affected.
