Abstract

Bacterial wilt, caused by Ralstonia, solanacearum, is a very destructive disease to tomato plants (Solanum lycopersicum) in Korea. This study was undertaken to find out the growth inhibitory effect bactericides on bacterial wilt pathogen of streptomycin, oxytetracyclin streptomycin sulfate WP and significantly suppressed the growth of bacterial wilt pathogen. Copper hydroxide WP showed control value of 62.5%. Therefore, it is concluded that the bactericide used in this study showed strong inhibitory effect to tomato bacterial wilt and they can be recommend to control the disease. And also, Copper hydroxide WP may be effective for control of bacterial wilt of tomato in conventional culture, farming without agricultural and organic farming.

국내에서 Ralstonia solanacearum에 의한 풋마름병은 토마토 재배에 심각한 피해를 주고 있다. R. solanacearum에 의한 풋마름병을 방제하기 위한 약제를 선발하기 위하여 5종 항생제를 이용하여 균에 대한 생장 억제 효과와 포장에서의 토마토 풋마름병 방제효과를 조사하였다 R. solanacearum에 대한 생장억제효과를 조사한 결과, streptomycin 수화제, oxytetracyclin streptomycin sulfate 수화제, oxolinic acid 수화제는 병원균에 대한 생육억제 효과가 우수하였다. 포장에서 토마토 풋마름병에 대한 방제효과 시험을 실시한 결과, copper hydroxide 수화제가 62.5%의 가장 높은 방제효과를 나타내었다. Copper hydroxide 수화제는 친환경유기농자재에 등록된 약제로서 관행 재배뿐만 아니라 토마토 친환경 재배시에도 풋마름병 방제에 사용할 수 있을 것이다.
