초록

본 연구는 고추 역병 방제시 유기합성 살균제의 사용량을 감소하기 위하여 수행되었다. 고추 역병 방제를 위하여 두 개의 미생물농약과 두 개의 살균제의 혼용처리 효과를 실내, 온실, 포장에서 확인하였다. 미생물농약과 살균제를 혼용하여 토양 관주 시 추천사용농도의 절반농도로 희석하여 시험을 진행하였다. 온실 포트검정 결과 B. pumilus QST2808와 De (dimethomorph + ethaboxam) 혼용처리조합이 2개의 미생물농약(B. pumilus QST2808, P. polymyxa AC-1)과 2개의 살균제(De, Mo) 혼용조합으로 이루어진 총 4개의 혼용처리 조합 중 역병 억제효과가 가장 좋았다. 또한 B. pumilus QST2808와 De 혼용조합은 살균제 De나 Mo 단독처리와 비슷한 억제효과를 나타내었다. 포장시험에서는 역병 방제를 위하여 미생물농약(B. pumilus QST2808, P. polymyxa AC-1)과 유기합성 살균제 De (dimethomorph + ethaboxam)을 혼용하여 7-10일 간격 4회 처리시 78.8%-82.0%의 방제가를 나타내었으며, 살균제(De, Mo) 각각을 단독처리 하였을 경우에는 65.7%-85.8%의 방제가를 나타내었다. 결과적으로 화학농약의 사용량 절감을 위해 미생물농약과 화학농약의 혼용 처리는 가능한 방법으로 추천할 수 있을 것이다.

This study was conducted to reduce the using amount of chemical fungicides for the control of red-pepper Phytophthora blight. Effect of combination application of two microbial fungicides and two chemical fungicides for the control of red-pepper Phytophthora blight was examined in vitro, in greenhouse and under field conditions. Each microbial fungicides and chemical fungicides was two-fold diluted and mixed-soil drenched. In the greenhouse pot assay, the mixed application of B. pumilus QST2808 and a mixture of dimethomorph + ethaboxam (De) among four mixed applications of two microbial fungicides (B. pumilus QST2808, P. polymyxa AC-1) and two chemical fungicides showed the highest control effect against Phytophthora blight. Also, control effect of mixed application of B. pumilus QST2808 and De was similar to that of single application of De (dimethomorph + ethaboxam) or Mo (mancozeb + oxadixyl). In the field test, when the microbial fungicides (B. pumilus QST2808, P. polymyxa AC-1) and the chemical fungicide(De) for the control of Phytophthora blight of red pepper were mixed-soil drenched four times at 7~10 day-intervals, the control values were in the range of 78.8% to 82.0%. On the other hand when each of the two chemical fungicides (De, Mo) were soil drenched four times at 7~10 day-intervals, the control value were 65.7% to 85.8%. Consequently, the mixed application of the microbial fungicides and chemical fungicides could be recommended as a control method for reducing the using amount of chemical fungicides.
