<![CDATA[:Fusarium wilt disease is one ofthe important disease of tomato plant that need to be controlled. It can decrease the productivity of the plant. The disease can be usually controlled by using chemicalfungicide which very expensive and can damage the environment. So it needs an alternative control method such as using biological fungicide. Curcuma domestica is one of plants that can be used as a biological fungicide. The aims of this research were to known the effectiveness of the C. domestica rhizome extract to the fusarium wilt diseases intensity and the concentration of the extract that effective to control fusarium wilt diseases in tomato plant. This research was done according to the experimental method employing a Completely RandomizedDesign (CRD). The treatment used C. domesticaextract with concentration 0% (K0), 5%(K1), 10%(K2), 15%(K3), 20%(K4), 25%(K5) and 30%(K6) applied on rhizosphere of tomato plant that has been previously invested by Fusariumoxysporuminoculum.The data wereanalysed with analysis of varian (F test) with the confidence level 95% and 99%. The result shown that the extract of C. domesticarhizomes did not effectively control fusarium wilt disease in the plant.]]>
