Rice Tolerance to Saflufenacil in Clomazone Weed Control Program

Table 5

Rice (Orza sativa L.) visible injury at 6 and 12 days after application (DAA) in response to postemergence application (4- to 6-leaf stage, V4-V6) of saflufenacil following preemergence application of clomazone. Saflufenacil results were averaged across clomazone rates, and clomazone results were averaged across saflufenacil rates.

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