This study was conducted to investigate the weeding effect of several soil application herbicides and covering materials on Japanese hop (Humulus japonicus Sieb. and Zucc.). When treated with the herbicides simazin WP and dichlobenilㆍimazaquin GR in non-cultivated land, weeding efficacy was 90% and 100%, respectively. Especially, H. japonicus of about 150cm height was effectively controlled by soil application with dichlobenilㆍimazaquin GR. H. japonicus was also controlled fully by covering materials, two fold of blackout curtains, black cover sheets and black polyvinyl.
