In peanuts cultivated in plots that were either artificially infested with Verticillium dahlias or non-infested, soil application of FeEDDHA or foliar application of Ryplex (Fe, Zn, Cu and Mn) significantly increased yield only in plots where the fungus was present. Addition of FeEDDHA to eggplants infected with V. dahliae significantly reduced disease severity in calcareous soil. Coprogen B was the predominant siderophore produced by seven different strains of V. dahliae during a growth period of up to 18 days. Low amounts of dimerum acid and an additional unidentified siderophore were also detected. However, a decrease in coprogen B with a concomitant increase in dimerum acid and pH were measured in culture filtrates during a longer incubation period. A correlation was established between the pH value of the medium and the relative concentrations of the two siderophores. The magnitude of siderophore repression by iron varied among different isolates. © 1988, Taylor & Francis Group, LLC. All rights reserved.
