Table 4: Visible rice (Oryza sativa L.) injury at 3, 8, 18, and 24 days after application (DAA) in response to postemergence application (4- to 6-leaf stage, V4-V6) of saflufenacil following preemergence application of clomazone. Data represents an interaction between rates of saflufenacil and clomazone for experiment conducted in 2009.

aInjury was estimated visually using a scale of 0 to 100% where 0 = no rice injury and 100 = rice death. bPlots that did not receive clomazone were treated with propanil plus quinclorac. cMeans followed by a different letter within a column are significantly different according to the Tukey’s test (P ≤ 0.05). dMeans were not different according to F-test at P ≤ 0.05.
