Available from your county Extension office are weed management guides for assistance in weed control in corn, soybeans, or forages. There is a separate guide for each commodity. The first half of the corn and soybean guides deals with soil-applied herbicides and the second half is for postemergence herbicides. These guides include information on pre-mixes and what is in the pre-mix, expanded weed control tables, information on application timing, comments for each of the herbicides, and much more. The forage guides cover alfalfa as well as grass forages. Contact your county extension office for these free guides. Or find them at the UD-REC website: http://www.rec.udel.edu/weedscience/WS_ManagementGuides.html.
