The herbicide ratings used in this chart are averages for the performance of these herbicides in the state when the herbicide is applied at labeled rates for crop production. Results may vary with location, rate of application, growth stage, and climatic conditions. Individuals are encouraged to alter the ratings to reflect their individual experiences with these herbicides under local conditions

Ratings: "C" = weed is generally controlled, "P" = weed is injured or partially controlled, "N" = weed is not normally controlled, "-" = not sufficient information to rate the performance of this herbicide on the weed.
