Bacterial black blight of mango
1996
Pinkas, Y.
Bacterial black blight of mango (Mangifera indica), is unrecognized in the classic growing areas of this fruit tree. The disease was first identified in Israel, which is located at the northern limit of the mango-growing zone, some 20 years ago. The causal agent was indentified as Pseudomonas syringae pv. syringae. Disease symptoms include black colored necrosis of branch bark, resulting in death of the recently developed canopy. In mild, warm winters the trees resist infection, but the disease is serious in years with cold, rainy winters. Under those extreme conditions the recommended control procedure, a spray program with 1 Bordeaux mix, becomes ineffective. To improve control sanitation is recommended. The previous year's infected branches, which serve as the inoculum source, must be removed. Toward the end of winter, under rainy conditions, those branches release enormous amounts of bacteria which are dispersed by the rain itself and the recently developed branches are infected.
