Pyraclostrobin is a broad-spectrum fungicide that inhibits mitochondrial respiration. However, it may also induce systemic resistance effective against bacterial and viral diseases. In this study, we evaluated whether pyraclostrobin enhanced resistance against the bacterial spot pathogen, Xanthomona...

고추의 심각한 병해 중 하나인 세균점무늬병의 발현 양상은? | X. euvesicatoria에 의해 불규칙한 원형의 암갈색과 황색 반점 을 형성된 후 잎이 탈락되는 세균점무늬병은 고추에서 심각한 병 해 중의 하나이다(Jones 등, 2004; Obradovic 등, 2004). 최근 X. | |
Pyraclostrobin이란 무엇인가? | Pyraclostrobin은 광범위한 스펙트럼의 항진균 활성이 있는 퀴논외부저해제(Quinone outside inhibitor, QoI)로 작용하는 살균제이다. 기존 보고에 의하면 pyraclostrobin이 일부 세균병과 바이러스병에 대해 병 저항성을 유도한다고 알려져 있다. | |
Strobilurin 계통의 살균제 방제효과가 가장 크게 나타나는 살포시기는? | 1 데 치료 및 예방적 살포시기에 따라 그 방제효과가 크게 달라진다. 특히, 곰팡이 포자 발아 및 균사 성장 억제를 위해서는 병원균 접 종 전·후 24시간에 살포할 경우 효과가 가장 크다(Karadimos 등, 2005; Turechek 등, 2006). 본 연구에서도 pyraclostrobin의 고추 세균점무늬병에 대한 살포시기에 따른 방제효과면에서도 24 시간전에 살포할 경우에 66%의 방제효과를 나타냈고, 살포시기 가 병원균 접종시기보다 늦어질수록 방제효과가 낮아졌다. |
