Abstract : Mango malformation is an economically important disease, which causes gross deformations of vegetative and floral tissues in Mangifera indica. Fungi, mites, viruses, physiological factors, malformins and mangiferins are its reported causes. Recently, a role for stress ethylene has been implicated in mango malformation. Ethrel was found to stimulate the germination of spores of isolates of Fusarium sp. from mango cultivars at concentration from 5 ppm to 100 ppm. However, its higher concentration was toxic for spore germination. These findings are discussed in relation to higher population of Fusarium sp. in diseased tissues due to stress ethylene.
