Abstract
This study was conducted to evaluate the efficacy of herbicide mixtures of benzobicyclon and carfentrazone-ethyl in direct-seeding flooded rice. The efficacy of benzobicyclon mixtures and carfentrazone-ethyl mixtures was greater than that of pyrazosolfuron-ethyl + pyriminobac-methyl GR. Herbicide mixtures with benzobicyclon controlled average 97% and herbicide mixtures with carfentrazone-ethyl controlled average 95% 60 days after application. When compared with untreated control, no visual injuries were detected at single and double dosage of herbicide mixtures. The yield of rice increased in both benzobicyclon and carfentrazone-ethyl treatments when compared with pyrazosolfuron-ethyl + pyriminobac-methyl GR. Based on these data, combinations of these herbicides can be applied to provide effective weed management in rice field.
