The present invention relates to a saffum barkatum extract and a composition for preventing wilt diseases containing the same as an active ingredient, and more particularly, to an extract of Sapium baccatum Roxb. Or gallic acid (1) Chelating acids such as methyl gallate 2, corilagin 3, tercatain 4, chebulagic acid 5, chebulinic acid 6, quercetin-3, A composition for controlling plant bacterium diseases containing quercetin-3-O-beta-D-arabinopyranoside, 7 as an active ingredient, and a method for controlling plant bacterium diseases using the same The composition for controlling plant bacterium of the present invention is derived from a plant and is harmless to the human body and does not cause environmental pollution. (Agrobacterium tumefaciens), Burkholderia glumae (bacterial rice blight bacterium), Claviabacter microspora Ganensis subsp. For example, Clavibacter michiganensis subsp. Michiganensis, Dickeya chrysanthemi, Pectobacterium carotovorum subsp. Pectobacterium carotovorum subsp. Carotovorum, Pseudomonas cingulin pv. Actinidia (Pseudomonas syringae pv. Actinidiae), Pseudomonas cingulin pv. Pseudomonas syringae pv. Lachrymans, Ralstonia solanacearum, Zanthomonas arboricola pv. It exhibits antifungal activity against various phytopathogenic bacterium such as Xanthomonas arboricola pv. Pruni (peach bacterium) and exhibits excellent antifungal activity against tomato rose blight caused by Ralstonia solanaceae And thus can be usefully used for producing environmentally friendly high value added organic agricultural products.본 발명은 사피움 박카툼 추출물 및 이를 유효성분으로 함유하는 풋마름병 방제용 조성물에 관한 것으로, 사피움 박카툼(Sapium baccatum Roxb.) 추출물 또는 이로부터 분리된 갈릭산(gallic acid, 1), 메틸갈레이트(methyl gallate, 2), 코리라긴(corilagin, 3), 터카테인(tercatain, 4), 체부라직산(chebulagic acid, 5), 체부리닉산(chebulinic acid, 6), 쿼세틴-3-O-베타-D-아라비노피라노사이드(quercetin-3-O-β-D-arabinopyranoside, 7)을 유효성분으로 함유하는 식물세균병 방제용 조성물 및 이를 이용한 식물세균병 방제방법을 제공하기 위한 것으로, 본 발명의 식물세균병 방제용 조성물은 식물로부터 유래하여 인체에 무해하고 환경오염을 유발하지 않으면서 엑시도보락스 아베네 subsp. 캇
