Supplying markets in the off-season has been the biggest challenge as well as the greatest opportunity the market has presented to the growers. Mangoes are susceptible to a few problems, most of them affecting the fruit quality. These infections show up as brown spots in the flowers and panicle that grow in size and number, eventually causing the death of the flower. On the leaf, the disease starts as small, dark angular to irregular spots that merge together forming large necrotic areas that may crack or break away. And young fruit is readily infected.
Spots vary from small pinpoints to large in the wet weather.
This stage is responsible for the decay of mature fruits. When maturing, the infected fruit will have black spots, which may be swollen and cracked, penetrating deep inside the fruit. Scab is caused by the fungus Elsinoe mangifera, Bit and Jenkins. It mainly attacks young, expanding tissues on blossoms, leave, twigs and fruits. Infections are nearly circular spots 1mm to 2mm in diameter, dark brown to black in color.
