Abstract

Field experiments were conducted to compare barnyardgrass control and rice grain yield following a single postemergence (POST) application of propanil plus clomazone with single or repeat POST applications of propanil alone or single POST applications of propanil plus pendimethalin, molinate, quinclorac, or thiobencarb. In four of 10 experiments, propanil plus clomazone controlled barnyardgrass better than single or repeat applications of propanil alone or single applications of propanil plus pendimethalin, molinate, quinclorac, or thiobencarb. The most consistent increase in rice yield over a single application of propanil occurred where clomazone was applied in mixture with propanil.
