Although derived from a fungicide, the bioassays indicated that several new compounds had good herbicidal activities. At 37.5 g a.i./ha, compound 5c showed 100% inhibition against Abutilon theophrasti, Amaranthus retroflexus, and Eclipta prostrata, which was better than mesotrione. Compound 5e had a broad herbicidal spectrum against broadleaf weeds. The present work indicates that 5c and 5e may serve as
