Fungicidal and Fungistatic Effects of Carboxin on<i>Ustilago nuda</i>

Abstract

(...) Paradoxically, carboxin has a fungicidal effect on hyphae of U.n. at concentrations lower than those at which it exhibits only a fungistatic effect. In contrast, using the same methodologies, the respiratory inhibitors antimycin A and carbonyl cyanide m-chlorophenyl-hydrazone were increasingly fungicidal with increased concentration. Respiratory inhibitors probably have fungicidal effects only when a certain minimum of energy for autolysis is available
