Last Check Chart for Problem Weeds in Corn and Soybeans

Mark VanGessel, Extension Weed Specialist;

The regional weed scientists have put together a quick reference chart for herbicide options to control the “BIG 3” herbicide-resistant weeds in the region, horseweed or marestail, Palmer amaranth and common ragweed. Use these charts in combination with other resources, such as the Mid-Atlantic Weed Management Guide, yet it will provide a final, “Last Check” to be sure you have the right herbicides in the tank. There is one for corn and one for soybeans.

Print them out and post one near your workspace on one in the mixing shed.
