Reminder of the “Last Check Chart for Problem Weeds in Corn and Soybeans”

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

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. These charts 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.

Soybeans: LastCheckSoybean

Corn: LastCheckCorn

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