Means followed by the same letter are not statistically different according to Fisher’s protected LSD ().
Timings that did not meet the assumptions of ANOVA are reported as means followed by the standard error of the mean (SE).
Glyphosate applied as Roundup PowerMax.
Imazethapyr applied as Newpath.
Glyphosate rates are in “g ae/ha.”
