Post-emergence herbicide spraying has been significantly delayed. Herbicides applied this season will probably not have as much time to breakdown prior to planting in 2020. Additionally corn and soybeans will be at many different growth stages when we get the opportunity to spray so correctly staging plants will be very important. Bill Verbeten and I discuss the cutoff stages for herbicide applications to corn and soybeans along with rotation intervals for post applied herbicides.
