【 摘 要 】

Chemical weed control of Commelina species (wandering-jew) is sometimes unsatisfactory. This work was carried out to observe the effect of herbicides on Commelina species at post-emergence. C. benghalensis, C. villosa, C. diffusa and C. erecta were treated with carfentrazone-ethyl (30 g ha-1 and 50 g ha-1), glyphosate (960 g ha-1), carfentrazone-ethyl plus glyphosate (30 + 960 g ha-1), sulfentrazone plus glyphosate (150 + 960 g ha-1), and a control, when the plants displayed 15 to 25 cm long stems. The experimental design was completely randomized with four replications. Commelina chemical control was different among species. Best control was achieved with C. benghalensis and C. erecta had the worst level of control. The treatment with carfentrazone-ethyl plus glyphosate showed the best results on the control of these four Commelina species, compared to other applications.
