초록

흰가루병 방제를 위하여 다양한 작물에서 발생한 흰가루병균을 채집하여, 흰가루병균에 기생되어 있는 Ampelomyces quisqualis를 분리하여 오이흰가루병방제에 우수균주로 선발된 A. quisqualis 94013(AQ 94013)에 대하여 오이에 등록되어 있는 살균제와 살충제가 AQ94013의균사생장 및 포자발아율에 미치는 영향을 조사하였다. 그리고 AQ94013이 기생력을 증진시킬 수 있는 전착제를 선발하기 위하여 전착제와 혼용 시험을 수행하였다. AQ94013의 포자발아 및 균사생장정도는 공시한 34종의 살균제를 첨가한 배지에서 검정한 결과, 흰가루병 약 triadimefon, pyrazophos, 노균병약 dimethomorph, kasugamycin+copper oxychloride, dichlofluanid + copper oxychloride, copper hydroxide, tribasic copper sulfate, 이외에 잿빛곰팡이병약 iprodione, vinclozolin, procymidon 과 공시한 11종의 살충제중에서 immidacloprid, teflubenzuron, bifenthrin, ethofenprox, deltamethrin, phenthoate이 AQ94013의 포자발아와 균사생장에 영향을 적게 미쳤다. 오이흰가루병균에 대한 A. quisqualis 94013 의 기생력을 증진하는 전착제는 mineral oil로서 방제효과를 7.9%향상시켰다.

A promising hyperparasite, Ampelomyces quisqualis 94013(AQ94013) was selected as a biological control agent to cucumber powdery mildew caused by Sphaerotheca fusca. Effect of agrochemicals on mycelium growth and spore germination of AQ94013 and effect of spread stickers on hyperparasitical activity of AQ94013 to powdery mildew pathogen were evaluated. Finally it was confirmed that mycelial growth and spore germination of AQ94013 on potato dextrose agar amended with two fungicides for controlling powdery mildew, triadimefon and pyrazophos; five fungicides for controlling downy mildew, dimethomorph, kasugamycin+copper oxychloride, dichlofluanid+copper oxychloride and tribasic copper sulfate; three fungicides for controlling gray mold, iprodione, vinclozolin and procymidone; and six insecticides immidacloprid, teflubenzuron, bifenthrin, ethofenprox, deltamethrin and phenthoate were slightly reduced. Addition of mineral oil in the spore suspension of AQ94013 enhanced 7.9% control value to cucumber powdery mildew.
