Abstract

Three diffeerent types of symptoms were observed according to the pathogen associated with the rhizomes. The maximum rotting was observed in case when Pythium aphanidermatum was inoculated first followed by Fusarium solani. There was no interaction in case of root knot nematode Meloidogyne incognita and Pythium aphanidermatum. Average per cent germination of the rhizomes were increased significantly in each treatment and maximum in case of Alliette(.25%). The per cent pre & post drenching rotting was minimum in case of Alliette, Burgandy mixture, Dithane-M 45 and Difolatan. These fungicides also increase the yield of rhizome significantly.

뿌리썩음증상은 병징에 따라 3가지로 대별되었다. 뿌리썩음증상은 Pythium aphanidermatum을 선접종 후 Fusarium solani를 후접종 하였을 때 가장 심하였다. 뿌리혹선충과 Phthium aphanidermatum과의 상호작용은 없었다. 근경 발아는 각 처리에서 현저히 증가하였고 Alliette 0.25% 처리에서 가장 높았다. 토양관주에 의한 치료 및 예방효과는 Alliette, Burgandy mixture, 다이센 M-45, 디포라탄이 우수하였으며, 수량도 증가하였다.
