구기자 탄저병 방제를 위한 살균제를 선발하기 위하여 13개의 탄저병 균주는 구기자의 청양재래 품종에 대해서 숙과와 미숙과 모두에서 상처 접종 시 병원성이 강하게 나타났다. 또한 15종 살균제의 균사생육 억제 효과를 실내 검정하여 탄저병균에 대한 균사 생장 억제 효과가 우수한 dithianon WG, tebuconazole SC, tebuconazole WG, trifloxystrobin+tebuconazole SC, azoxystrobin SC 및 polyoxin D zinc salt+carbendazim WP 등 6종의 살균제를 선발하였다. 선발한 살균제들의 포장에서 병 방제 효과를 조사한 결과 dithianon WG, tebuconazole WG, trifloxystrobin+tebuconazole SC, tebuconazole SC 및 azoxystrobin SC 등 5종의 살균제가 높은 방제효과를 나타냈다.
Anthracnose caused by Colletotrichum spp. has been known as a significant disease which commonly infects to the fruits of Chinese matrimony (Lycium chinese) in the field conditions. To select effective fungicides for the control of Chinese matrimony anthracnose, the antifungal activity of 15 fungicides were evaluated with 13 different strains of Colletotrichum spp. in the laboratory condition. Six fungicides (Dithianon WG, Tebuconazole SC, Tebuconazole WG, Trifloxystrobin + Tebuconazole SC, Azoxystrobin SC and Polyoxin D zinc salt + Carbendazim WP) out of them, showed effective suppression with the mycelium growth of pathogenic fungus, and were selected to test in vivo of the field condition. Five fungicides, Dithianon WG, Tebuconazole WG, Trifloxystrobin + Tebuconazole SC, Tebuconazole SC and Azoxystrobin SC, were significantly effective to protect anthracnose of Chinese matrimony, the variety "Chungyang Jerae".
