Zusammenfassung:	A method and composition for the treatment of iron chlorosis in plants using hydroxamic acid-type siderophores. Siderophores of this type are ferric-specific chelators, which are produced by certain microorganisms grown in iron-free environments. The current invention contemplates the use of the siderophore rhodotorulic acid to treat and prevent iron chlorosis. Rhodotorulic acid is produced by the yeast Rhodotorula pilimanae. The siderophore may be applied to the plant by a variety of methods including by soil application, foliar spray or direct injection into the plant.
