Take action against herbicide-resistant weeds. The Take Action Herbicide Lookup Tool helps you diversify your herbicide site of action (SOA) to prevent herbicide-resistant weeds from spreading.

Using multiple herbicide sites of action (SOAs) is key to effectively manage your fields to combat or prevent a herbicide resistant weed problem on your farm. With this handy tool, you can:
• Quickly identify the SOA of the herbicide brand or active ingredient you have used before
