Visual estimates of percent weed control following different herbicide treatments in 2017 at Ji’ning (JN) and Shi’zui’shan (SZS). aVisual estimates of percent weed control were recorded 20 and 40 d after treatment (DAT) using a scale of 0 to 100% where 0 = no weed control and 100 = complete weed control. bDifferent letters are significantly different at the P < 0.05 level according to Fisher’s protected LSD test.
