Penggunaan jamur endofit dari terong belanda (solanum betacea) untuk mengendalikan Fusarium oxysporum f.sp. capsici dan Alternari solani secara in vitro

Abstract

Amalia Tri Kurnia. Using of endophytic fungi from Solanum betacea to control Fusarium oxysporum f.sp. capsici and Alternaria solani in vitro, supervised by Mukhtar Iskandar Pinem dan Syahrial Oemry. This research aimed to know efectivity of endophytic fungi from Solanum betacea to control Fusarium oxysporum f.sp. capsici and Alternaria solani in vitro. This research was conducted on Plant Disease Laboratory of Fakultas Pertanian USU on May 2013 until January 2014, used Randomized Complete Design with two factor in 2 replicate. First factor was kind of pathogen (Fusarium oxysporum f.sp. capsici and Alternaria solani). Second factor was kind of endophytic (E1, E2, E3, E4, E5, E6, E7, E8, E9, E10, E11, E12, E13, E14, E15). The result of this research showed that kind of phatogen, kind of endophytic and interaction between them so significantly effect on inhibiting zone, growth width of colony and diameter of colony. The best result was showed on E6 to control F. oxysporum and A. solani with 56.89% and 54.10 % inhibiting zone.
