Herbicide Resistance and Integrated Weed Management

How to Manage Herbicide Resistance with IWM

Integrated weed management (IWM) describes the practice of using multiple control tactics to manage weeds. This GROW educational page will dive deeper into how integrated approaches using both chemical and non-chemical tactics can help prevent and manage herbicide-resistant weeds on your farm.  It presents a comprehensive overview of herbicide resistance management through a series of boxes, which open up to give the reader detailed answers to 10 fundamental questions. Let GROW be part of your solution to better weed management.

1. What is Integrated Weed Management (IWM)?
2. What strategies are important for implementing IWM?
3. How do herbicide-resistant weeds spread?
4. How do I select good herbicide options?
5. How do I manage target-site vs. non-target site resistance?
6. How important are herbicide rotation and tank-mixing?
7. What non-chemical strategies are available and helpful?
8. What innovative technologies are on the horizon?
9. How can I develop an IWM strategy?
10. How are other farmers using IWM?
