Abstract
This study was attempted to select an antagonist against Phytophthora blight of red-pepper caused by Phytophthora capsici. The three strains, A-35, A-67 and A-183 were isolated from the rhizosphere in soil where red-pepper had been cultivated continuously for a long time, and the strain A-83 was estimated to be the strongest antagonist against P. capsici. The A-183 strain was identified as a strain of Pseudomonas sp., showing the maximum antifungal activity, when cultured at
고추 역병균(疫病菌)인 Phytophthora capsici의 방제(防除)를 위한 생물농약(生物農藥)을 개발(開發)하기 위하여 고추재배지토양(栽培地土壤)에서 균원시료(菌源試料)를 채취(採取)하여 우수(優秀)한 항균활성(抗菌活性)을 가지는 물질(物質)을 생산(生産)하는 균주(菌株)를 순수분리(純粹分離)하고 동정(同定)하였다. 대치배양(對峙培養)에서 A-183균주(菌株)가 A-35와 A-67보다 P. capsici의 생육을 크게 저해(沮害)하였으며 배양액(培養液)을 membrane여과 및 열처리(熱處理)(
