When is the best time to spray Queen Annes Lace (wild carrot) using Crossbow Herbicide on our 4 acre non-grazing pasture?


If you are planning to use a product like Crossbow Herbicide you would typically want a late summer/early fall application for some of the best results with a post-emergent heribicide. Wild carrot can be difficult to completely get rid of due to their seed cycle, so dilligence and product rotation will be needed, if possible. I have linked for you below a really helpful guide on Wild Carrot and it goes over its life cycle, timing and ingredient recommendations from Michigan State University through their tests and what they found successfull.
