Abstract : Mango trees in Egypt usually suffer from malformed vegetative and floral overgrowth that affects yield and quality of the crop. The disorder is manifested by the excessive production of abnormal small vegetative or floral buds on terminal twigs or inflorescences resulting in the occurrence of massive aggregations of various size and shape. From preliminary investigations with sequestrene 330 Fe(NaFeDTPA) with 10% metallic iron, or sequestrene 138 (HFeEDDHA) with 6% metallic iron, it can be safely concluded that severe iron deficiency is the main cause of the malformations.
