Abstract

This study was conducted to test effect of fungicides on the spore germination and mycelial growth of BotaniGard$^{(R)}$(Beauveria bassiana GHA). Eight fungicides, which are using for plant disease control in cucumber cultivation, with different concentration were mixed with conidia of GHA isolate for 0.5, 2, and 4 hours. The fungicides trifluminazol, fenarimol, ethaboxam, copper hydroxide and tetraconazol did significantly not inhibit on spore germination and mycelial growth. The trifluminazol, propineb and tetraconazol on high concentrations inhibited the mycelial growth of GHA. However, mixing time of fungicide with conidia of GHA did not affect in spore germination and mycelial growth. These results suggest that fungicide effect needed be checked before mycopesticide is applied in the field.

작물 재배 중 발생하는 다양한 병해충 방제를 위해 화학농약이 단독 또는 혼합제로 사용되고 있어, 살균제가 곰팡이 살충제 보타니가드(Beauveria bassiana GHA)의 포자 발아 및 균사 성장에 미치는 영향을 조사하였다. 오이 병 방제에 많이 사용되는 8개의 살균제를 4개 농도의 용액으로 만들어 곰팡이 살충제(보타니가드) 포자와 0.5, 2, 4시간 동안 혼합한 후 포자 발아와 균사 성장에 미치는 영향을 조사하였다. 살균제 트리플루미나졸, 페나리몰, 에타복삼, 코퍼하이드록사이드, 테트라코나졸은 포자발아와 균사 성장에도 영향이 없었으나 트리플루미나졸, 프로피넵, 테트라코나졸은 높은 농도에서 균사 성장 억제력이 증가하는 경향을 보였다. 살균제와 포자의 혼합시간은 포자발아와 균사성장에 영향을 미치지 않았다. 이러한 결과는 곰팡이 살충제와 살균제 혼합 또는 동일 포장 처리시 상호영향을 조사한 후 처리하여야 함을 의미한다.
