摘　　要：细辛叶枯病是我国首次发现的一种新病害。初步认定,病原菌为菌刺孢属(Mycocentrospora S P.)。该病发生普遍,为害严重,明显降低细辛产量和质量,严重影响细辛生产的发展。经1990～1992年在本溪县细辛主产区进行药剂防治试验,结果表明:在供试的8种农药里,以150倍多抗霉素防治效果最佳,防效为88.6％,同时细辛增产112％,种子增产69％;其次为代森锰锌,多菌灵和百菌清等药剂,也有一定防效。The leaf-wither disease of Asarum Siebldii Miq. has been found a new disease for the first time in China. We firmly believe from identification that pathogenetic fungus is Mycocentrospora sp. The disease breaks out widespead places, the harm is serious, the yield and quality of Asarwm Siebldii Miq. have been evidently decreased. We carried out controling-test with medicament at the main producing area in Benxi county between 1990-1992. The results show that the most effective medicament is Polyoxin with 150 times, the effective rate is 88.6%, the increased yield is112%, 69% with seed. The second is in order with Mancozed, Carbenazrim, and Chlorthalonil with some actions from 8 medicaments.
