I am planning for the fall with a cereal rye cover crop. This would be in corn fields where corn is off in late Sept. But in the spring, I like to apply canopy EX in march along with 2,4,D and roundup, to get ready for beans. How late into the spring can I kill off the cover crop and not hurt the beans. The canopy and 2,4,D literature says I need 2 weeks minimum before planting

question- will 2 week be enough time so the canopy or 2,4,D don't hurt the beans
