Abstract

ABSTRACT The green house research aimed to know the best isolate of T. harzianum in controlling Fusarium wilt , shallot production, and the effect of T. harzianum application time in suppressing the disease. Randomized block design was used with twelve treatments. Each treatment was replicated three times. The treatments were negative control, positive control as wel as extract of ginger isolate, banana isolate, shallot isolate, potato isolate, and ginseng isolates. The treatments were  applied a week before or after inoculation of the pathogen. The result showed that the antagonist extract of ginger isolate applied a week before inoculation decreased the disease intensity by 43.854%. The antagonist extract application applied before or after inoculation were not significant difference . The antagonist of potato isolate extract was the best in increasing number of plants per clump and tuber fresh weight resulting  9.7503 and 13.133 g, respectively. The best extract in increasing root growth was shallot extract. The ginger isolate extract increased root length by 17.672%.
