Fall Pre-Emergent Herbicide Timing Results and Takeaways
Mike Basedow, Tree Fruit Specialist
Eastern New York Commercial Horticulture
In the August TFN, David Bittner and I discussed his strategy of post-harvest applications of 2,4-D and clopyralid (Stinger) to clean up the herbicide strip and row middles of perennial broadleaves. In addition to making that application in the fall to manage your problem perennials, post-harvest can also be a good time to get your pre-emergent materials on to get a leg up on your annual weeds heading into the next growing season. In the next few paragraphs, we'll discuss some results from our ARDP funded project comparing fall and spring pre-emergent herbicide applications, and some strategies you can use to get the most out of your fall pre-emergent herbicide applications.
