膦酸钾（0.3毫摩尔）在体外抑制香蕉枯萎病菌（Fusarium oxysporum f.sp. cubense，Foe）小分生孢子的产生。另一个香蕉枯萎病菌分离株以及两个香石竹尖孢镰刀菌（Fusarium oxysporum f.sp. dianthi）分离株的产孢对膦酸盐不太敏感。该杀菌剂不会降低在其存在下产生的香蕉枯萎病菌孢子的活力，并且仅在高浓度（半数有效浓度ED(50)为30毫摩尔）时才抑制香蕉枯萎病菌小分生孢子的萌发。
Potassium phosphonate (0.3 mM) inhibited the production of microconidia by Fusarium oxysporum f.sp. cubense (Foe) in vitro. Sporulation of another isolate of Foc, and two isolates of F. oxysporum f.sp. dianthi was less sensitive to phosphonate. The fungicide did not reduce the viability of spores of Foc produced in its presence and inhibited the germination of microconidia of Foc only at high concentrations (ED(50) 30 mM).
