Abstract. Recent findings have demonstrated that the disease may be of fungal origin. However, several infectious diseases caused by many phytopathogens are deteriorating mango quality and quantity. Fortunately, malforma-tion is more damaging in regions of the world, such as India and Pakistan, than in areas with appreciable rainfall, such as southern Florida. The disease is caused by Fusarium subglutinans and it produces two types of symptoms, i.e., vegetative and floral. Darvas (1987) found that blossom malformation could be moderately controlled by stem injections of Fosetyl-Al and phosphorous acid (H3PO3). Mango malformation is a serious disease of Mangifera indica in tropical and subtropical regions of the world. Darvas (1987) found that blossom malformation could be moderately controlled by stem injections of Fosetyl-Al and phosphorous acid (H 3 PO 3).His work was taken a step further in the extensive testing of a … serious diseases of mango affecting almost all the varieties.29 Malformation disease, caused by the fungus Fusarium subglutinans, is a serious constraint reducing production.30 The disease is sometimes termed "blossom malformation," and this term is accurate when the flowering panicle is involved, but the symptoms can also 2. "Malformation disease of mango (Mangifera indica) initially noted in patches in India has now turned into a global menace wherever mango is grown.

Mango malformation is the fatal disorder of mango trees, which not only negatively affect plant health, but also reduces yield in many cultivars all over the world. Recently, malformin-A like substance(s) and other compounds possessing similar bioactivity has been detected in malformed panicles of mango at all stages of development. Phoma blight Phoma glomerata. Since malformed inflorescences do not bear fruit, MMD is a major constraint to crop production in affected areas. Mucor rot Mucor circinelloides. The disease spreads on a tree very slowly, but if left unchecked, can reduce yields in orchards. Physical alteration followed by chemical treatment like Prochloraz and benomyl spray results in the reduction of disease incidence and increment of yield. Mango malformation Fusarium subglutinans (Note: some debate remains as to complete etiology of this disease.) Malformation affects vegetative and flo-ral tissues of mango. However, the combination treatment between the growth regulator Cultar and the biocide Bio-Zeid was the most efficient treatment in this regard.

The affected plants develop swollen abnormal vegetative growth with short internodes. Treating a sick mango means correctly identifying mango disease symptoms. A four year study of malformation in mango (Mangifera indica L.) revealed that a single foliar spray application of 1000 ppm cobalt sulphate prior to flower bud differentiation in the first week of October successfully reduced floral malformation by 93,94,87 and 84% in each year respectively, as compared with the earlier recommended treatment of naphthalene acetic acid (100 ppm) and … where more than 50 … The aim of the present study was to assess the current disease position and devise an integrated strategy to control this malady in commercial orchards. Mango blossom malformation is a fungal disease caused by Fusarium spp. Mango malformation is the production of thick vegetative shoots at the growing tip and transformation of floral parts Into a compact mass of sterile flowers.

Darvas (1987) found that blossom malformation could be moderately controlled by stem injections of Fosetyl-Al and phosphorous acid (H 3 PO 3). The treatment proved useful to reduce the intensity of malformation of inflorescence during the subsequent years. The comprehensive treatment counteracted malformation successfully as symptoms of the malady were not detected in all trees including the control. Mango malformation disease (MMD) caused by Fusarium mangiferae severely affects the crop and is widely distributed in almost all mango-growing regions worldwide.
