Abstract
This experiment was carried out to clarify the effect of herbicide chlormethoxynil 7G, CNP 9G and butachlor 3.5/pyrazolate 6G on weed control and seedling growth in rice seedbed. Different quantities of the herbicides were applied as soil incorporation or surface broadcasting. At earlier sowing annual grasses such as Echinochlva spp. and Alopecurus spp. were dominated, but Cyperus spp. were dominated at later sowing. Weed suppression by herbicides was greater in soil incorporation than in broadcasting and chlormethoxynil 7G and CNP 9G application (30kg/ha) showed about 70% weed control, while butachlor 3.5/pyrazolate 6G (10-20kg/ha) showed 90 to 100% weed control. At lower rate of butachlor 3.5/pyrazolate 6G (10kg/ha) emergence ratio, healthy seedling ratio and relative growth rate of rice were higher, and phytotoxicity was lower than in the others.
