The Use of Aeromonas hydrophila to Control Fusarium Wilt Disease on Several Varieties of Sweet Sorghum (Sorghum bicolor (L.) Moench) Objective of this study was to test the effectiveness of A. hydrophila to control wilt disease caused by Fusarium sp. on several varieties of sweet sorghum. Results of this study showed that application of rhizobacteria affected the growth and the yield of sweet sorghum. Under in vitro condition, treatments with A. hydrophila isolate KtBlt2 could suppress the growth of the Fusarium sp. with inhibitory activity 76.06% when compared to control. Under field condition treatment P6 (treatment wilt A. hydrophila on variety FS-501) could suppress Fusarium wilt disease with the lowest disease incidence by 3.24%. It is necessary to test the stability of A. hydrophila as biocontrol agent against Fusarium sp. Keywords : A. hydrophila, Fusarium sp., sweet sorghum
