摘　　要：The phosphonate fertilizers, Calphos （calcium phosphonate）, Magphos （magnesium phosphouate） and Phosphoros （potassium phosphonate） were used in Jordan and showed a nematicidal effect. This study aimed to investigate the fungicidal effect of these fertilizers against the growth of the fungi, Fusarium proliferatum, Altrenaria solani, Pythium debaryanum and Penicillium digitatum. Results showed that the phosphonate fertilizer Calphos at the concentration of 1% mixed with potato dextrose agar （PDA） totally inhibited the growth of all studied fungi. Magphos （1%） delayed the growth of the fungus F. proliferatum and inhibited the growth of other tested fungi. While Phosphoros （1%） mixed with PDA inhibited the growth ofA. solani and P. digitatum even after 12 d of incubation and delayed the growth ofF. proliferatum and P. debaryanum compared with the growth of the fungi on the PDA only.
