Managing herbicide resistance costs

Farmers considering herbicide resistance strategies are looking at the economics first

By
There are several reasons many farmers haven’t yet adopted herbicide resistance management (HRM) plans. These include a lack of information, the complexity of different management strategies and limited time. But a major reason is still economics. Many farmers worry about the costs of implementing a resistance management plan, especially if they’re uncertain about the potential […] Read more
