The Disease Cycle of Mango Malformation Induced by Fusarium moniliforme var. subglutinans and the Curative Effects of Mangiferin-Metal Chelates

Evidence is presented to suggest that the bunchy top, die-back, abnormal inflorescence and blossom blight disease of Mangifera indica are interlinked and can be expressed as a disease cycle in mango malformation. The morphological and biochemical connections among these symptoms, induced by Fusarium moniliforme var. subglutinans Wollenw. and Reink., are appraised. Partial control of the mango malformation has been accomplished by spraying the diseased parts with mangiferin-Zn²⁺ and mangiferin-Cu2+ chelates. The salutory effect of niangiferin-metal chelates is evidenced by the revival of normal balance of mangiferin and the micronutrients in the diseased parts, dechne in the fungal population and emergence of healthy shoots.
