Weeds that escape control not only impact crop yields but also produce seeds that contribute to future problems. While it is too late to protect crop yields from weed-related losses, in some situations the quantity of weed seed that is produced can be reduced. Historically, 2,4-D applications in corn have been been the most popular late-season treatments. The effectiveness of these applications is dependent upon the sensitivity of the weed to the herbicide and the maturity of the weed seed at the time of application.
