The primary bioassay shows that the title compound exhibits an excellent inhibiting activity towards Echinochloa crusgalli (L.) Beauv., Digitaria adscendens, Brassica napus, Amaranthus retroflexus
. Under the postmergence, its inhibition rates to Echinochloa crusgalli (L.) Beauv., Digitaria adscendens, Brassica napus, Amaranthus retroflexus
reach 93.7%, 100%, 28.8% and 100% respectively at a concentration of 1500 g/ha.

[C.sub.3] broadleaves were composed almost entirely (>95%) of three species; lambsquarters (Chenopodium album L.), velvetleaf (Abutilon theophrasti Medik.) and Virginia copperleaf (Acalypha virginica L.); [C.sub.4] broadleaves were exclusively redroot pigweed (Amaranthus retroflexus
