More Multi-State Herbicide Efficacy Tables
As promised in the last issue of this Bulletin, this issue contains additional tables with information on multi-state herbicide efficacy, as compiled by Marshal McGlamery. The tables in this issue are efficacy ratings for corn herbicides on a variety of broadleaf species. Information for soybean herbicides will follow in subsequent issues of this Bulletin.
This week, observe that the note following Table 2 applies to the other weed tables as well.
Correction. There were several errors in some of the herbicide efficacy tables of the previous edition of this Bulletin. Table 3 (Efficacy of Corn Herbicides: Barnyardgrass) indicated that Iowa ranked Axiom for control of barnyardgrass; however, the rating of "9" belongs under the Illinois column. Additionally, Nebraska also rates Axiom on barnyardgrass ("9"), crabgrass ("9"), giant and yellow foxtail ("9"), fall panicum ("9"), and sandbur ("9").
