Integrated Crop Management News

Document Type


Publication Date



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.
