 The antifungal effects of citralis colosynthes extract, hexane, chloroform, methanol, and water were tested in vitro on fusarium oxysporum F, SP lycopersici, SACC, WC Snyder, and H.N. Hans, FL, the causal agent of fusarium wilt. Of these, methanol and water extracts at 10% showed the highest inhibition of mycelial growth of FL by 12.32 and 23.61 millimeters respectively. The antifungal compounds were identified through Fourier transform infrared spectroscopy and gas chromatography mass spectroscopy. The methanol extract was compatible with the biocontrol agent trichoderma viride. The antagonistic fungi were cultured under laboratory conditions using sorghum seeds. Both trichoderma viride and citralis colosynthes methanol extract were tested alone and together against FL under both in vitro and in vivo conditions. The combination of TR.
