  • In order to select the effective herbicides on polyethylene film mulching culture of galic (Allium sativum L) for weed control in early and low temperature condition, several experiments were conducted at the Chungbuk Provincial Office of Rural Development from 1978 to 1982. The dominated weed in the open field was Chenopodium album (98.1%), and there were many Rvrippa globosas (39.7%), and Dtgitaria sanguinalis (34.3%) in the polyethylene film mulching culture. Effective herbicides in polyethylene film culture were alachlor EC, pendimethalin EC, oxyfluorfen EC, and acifluorfen EC. After the 15th May, metabenzthiazuron WP and prometryne WP for the gramineous weeds were effective. There was a little chemical injury on acifluorfen EC application, but not another influence on the yield. With the effective herbicides application in the polyethylene film mulching culture, yield (22-23%) and profits (26.84) to the nonmuiching culture were increased. Increase of yield (20%) and profits (56%) in black opaque polyethylene film mulching culture compared with the conventional culture was possible.
