Abstract

Fusarium wilt desease caused by Fusarium oxysporum f.sp. cubence (Foc) one the important desease on banana around the world. The purpose of this research was to recognize surface and endophytic colonization capability of Trichoderma viride (T1sk) on several banana cultivar roots and its effect against Fusarium wilt disease and increasing banana seedling growth. The experiment was divided into 2 parts that were colonization effect against Fusarium wilt disease development and colonization capability of T. viride (T1sk) on roots of several banana cultivars. The parameters observed were: 1) surface and endophytic colonization capability of T. viride (T1sk) on various banana seedling roots, 2) incubation period, 3) percentage of symptomatic leaves, 4) increase of leaves amount, 5) increase of plant height, 6) Stem circle and 7) dry weight of banana seedling biomass. The result showed that highest surface colonization capability of T. viride (T1sk) found in Barangan and Kepok cultivars and endophyte colonization found in Kepok cultivar. The surface colonization capability of T viride (T1sk) on the roots of Barangan and kepok reached 93, 33% and the ability of being endophyte 43, 33% and 38, 33% could reduce Fusarium wilt disease on banana seedling and increase seedling growth.
