2 Table of Contents Introduction List of Herbicides, sorted by common name List of Herbicides, sorted by trade name List of Crops List of Weeds Weed Control Ratings for each Herbicide Herbicide effectiveness against each weed Same weed control ratings as above. Labeled and tolerant crops for each herbicide L = The herbicide is labeled for use on this crop. T = The crop appears to be tolerant to the herbicide, but use may not be registered. Herbicides labeled or tolerant for each crop This list is grouped and sorted by herbicide common name. Weeds controlled, stage of application, and level of control are given for each weed. For best use of this list, search by herbicide name. The following codes are used in this list: Stage of application: The first number is for preemergence weed control rating. The second number is for postemergence weed control rating. pre = preemergence post = postemergence ppi = preplant incorporated Description of numbered ratings: 0 = No known activity. 1 = Excellent control of the weed at this stage. 2 = Fair control of the weed at this stage. This guide is for informational purposes only. It is not intended to provide herbicide information.
