Abstract
참깨 시들음병과 역병에 대한 괄항균(括抗菌) Streptomyces spp.의 길항현상과 생물학적 방제 효과를 구명코져 참깨 시들음병(F. oxysporum f. sp. vasinfectum)과 역병(P. nicotianae var. parasitica)이 발생한 포장에 이병주로 부터 병원균을 순수분리(純粹分離)하였고 괄항균(括抗菌)은 충북일원의 고추, 참깨포장의 72점의 흙으로 부터 공시 병원균에 효과있는 괄항균(括抗菌)을 대치배양법(對峙培養法)으로 선발하였다. 선발된 괄항균(括抗菌) St-11 과 St-20 을 공시하여 병원균에 대한 균사저지원, 괄항균(括抗菌) 배양 여액에서의 병원균의 생육저지, 발아억제 빛 lysis 를 관찰 조사하였고 괄항균(括抗菌) 현독액(縣獨液 )(St-11) 을 종자에 처리할 경우 참깨생육에 아무런 영향이 없었다. 온실에서 괄항균(括抗菌)의 토양접종에 의한 참깨시들음병과 역병에 대한 방제효과는 병원균 단독 접종구에 비하여 40-78% 의 방제효과를 보였다. 【This study was conducted in order to find out biological control of sesame wilt and blight caused by Fusarium of oxysporum f. sp. vasinfectum and Phytophthora nicotianae var. parasitica by using Streptomyces spp. Two sesame pathogens, Fusarium oxysporum f. sp. vasinfectum and Phytophthora nicotianae var. parasitica were purely isolated from diseased sesame plants of the field. Streptomyces species were isolated from 72 soil samples collected from red pepper and sesame uplands in Chungbuk and selected as antagonists according to the results of dual culture. The selected Streptomyces isolates such as St-11 and St-20 were confirmed their antagonistic effect through mycelial inhibition zone and inhibitory effects on the mycelial growth of the pathogens by culture filterate of the antagonists. Inhibitory effects on the conidial germination of Fusarium oxysporum vasinfectum and Phytophthora nicotianae parasitica by the antagonists were also tested in addition to mycelial Iysis. The antagonists St-11 and St-20 showed inhibitory effect on growth of sesame seedlings after seeds soaked in the suspension. Effect of soil inoculation with antagonist St-11 showed 40 to 78 percent of control effect for two diseases in comparison with control under greenhouse.】
