Site of Action Lookup Tool

It important to use multiple herbicide SOAs to effectively manage your fields to combat or prevent a herbicide-resistant weed problem on your farm. The diversification tool helps you to quickly identify the SOA of popular herbicide brands you may be using or considering. Because it’s important to use diverse SOAs, the tool will also provide a list of products with the same SOA that won’t provide the diversification recommended. Save the mobile version of this tool as a bookmark on your mobile device’s home screen for easy access.

Enter the trade name or active ingredient of the herbicide you used last year to identify other herbicides that fall within that same site of action.
