계면활성제를 이용한 역병과 오이 노균병 방제 = In Vivo Antifungal Activities of Surfactants against Tomato Late Blight, Red Pepper Blight, and Cucumber Downuy Mildew

다국어 초록 (Multilingual Abstract)

Anionic surfactants such as sodium dioctyl sulfosuccinate (SDSS) and sodium dodecylbenzene sulfonate
(NaDBS) and a nonionic surfactant, polyoxyethylene oleyl ether (OE-7) were tested for their protective, curative, and
persistent activities on tomato late blight (TLB, Phytophthora infestans), red pepper blight (RPB, P. capsici), and
cucumber downy mildew (CDM, Pseudoperonospora cubensis). They exhibited a strong protective activity on TLB,
RPB, and CDM. Among them, NaDBS (500 μg/ml) showed the most in vivo antifungal activities(1-day protective
activity) with control values of 99%, 100%, and 85% against TLB, RPB, and CDM, respectively. However, the three
surfactants represented a weak disease controlling efficacy on TLB, RPD, and CDM in a 1-day curative application.
SDSS and NaDBS exhibited a good persistent activities on TLB and RPB. Especially, NaDBS, at 500 μg/ml, showed
control values of more than 88% on TLB and RPB in a 7-day protective application. The results indicate SDSS and
NaDBS have a potential for the control of TLB, RPB, and CDM in the fields.
