For our final episode of season 8, we have agronomists Kyle Okke, Jason Hanson and Jeff Nagel on to discuss the economics of weed control for growers. They cover their major weed challenges and how additional inputs like machinery cost, fertility, and pest management are all factored into planning for ’25. Let’s wrap up this season by reflecting on ’24, and looking into ’25!
