Abstract : Studies in which young mango trees were inoculated with Botryodiplodia theobromae confirmed that the fungus is a weak parasite which invades mango tissue only when the plants are affected by external factors. Mango dieback in the Sonsonate district of El Salvador appears to be associated with the occurrence of long periods of drought, the effects of which are exacerbated by shallow rooting caused by a soil hardpan.
