摘要：

Topramezone is a newly introduced herbicide for use in maize. Field experiments were carried out on several locations during a three year period. Untreated check (weedy check), two rates of topramezone (low a.i. 50.4 and high 67.5 g . ha(-1)) and standard treatment (nicosulfuron + bentazone + dicamba a.i. 40+640+180 g . ha(-1)) were applied at maize growth stage 4 - 6 leaves. Major weeds present were Amaranthus retroflexus, Ambrosia artemisiifolia, Chenopodium album, Chenopodium polyspermum, Echinochloa crusgalli and Setaria glauca. All herbicide treatments controlled broadleaved weeds more than 95 %. A low dose of topramezone reduced Echinochloa crus-galli from 3 8 to 100%, whereas a high dosage resulted in 100% control. Both doses of topramezone controlled Setaria glauca at the same level, 68.9 - 100%.
