Erwinia herbicola(EH) 채소 연부병 방제를 위하여 충북 청원군, 진천군 및 충남 연기군 일원의 채소 경작지 토양으로부터 형광성을 나타내는 Pseudomonas속 1, 196균주를 선발하고, 연부병균 Erwinia herbicola에 대한 생육억제력과 생물학적 검정으로 발병억제력이 강한 2균주를 선발하여 Pseudomonas fluorescens S4(PS4)와 Pseudomonas fluorescens S65 (PS65)로 동정하였다. 배춧잎을 이용하여 분리길항균의 연부병균에 대한 생물학적 억제력을 확인한 결과 상당한 발병억제력을 확인하였다. 이들 두 균주가 가장 높은 길항력을 나타내는 조건은 배양 초기배지의 pH를 7.0으로하여 25℃에서 3일간 배양했을 때였다. 화학농약 및 항생물질에 대해 2균주 모두 benomyl, propamocab hydrochloride, fosethyl-Al-folpet, vancomycin, penicillin 및 lincomycin에 내성을 나타냈고, PS4균주는 erythromycin에 대해서도 내성을 나타냈다.
