Abstract
Experiments were conducted on Sharkey clay and Gigger silt loam soils in northeast Louisiana from 1990 through 1993 to compare season-long barnyardgrass control, rice yield, and estimated economic returns with single and multiple applications of propanil alone or with molinate or thiobencarb. Multiple herbicide applications were more effective than single applications in controlling barnyardgrass and provided the greatest rice yields and economic returns. Applying residual herbicides with propanil improved barnyardgrass control in five of six experiments and increased rice yield and economic returns in three of six experiments.
