Rice Tolerance to Saflufenacil in Clomazone Weed Control Program

Table 3

Rice (Oryza sativa L.) visible injury at 22 DAE in response to saflufenacil and clomazone applied preemergence. Data represent an interaction between rates of saflufenacil and clomazone in 2010.

Saflufenacil rates (g ha^−1)	Visual injury^a
	Clomazone rates (g ha^−1)
	0^b	392	505
	%
0	0 c^c	15 bc	25 ab

200	6 a	23 a	40 a

^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).
