ANTHRACNOSE

Cause: The fungus Colletotrichum gloeosporioides.

Symptoms: dark spots that enlarge to irregular, black areas at ripe.

Control: After harvesting, orchard hygiene (weed removal, diseased dead branches, and pruning canopy for sunlight direction). Pesticide spraying (Carbenzim 500FL, Saipora 350SC) at 2 weeks before flowering, at fruit setting and at 4 weeks before harvest. For harvested fruit, use 0.1% Carbenzim 500FL or 0.55 mL/L Sportak®or 1.8ml/L Tecto (Thiabendazole) for 30 s.

Control: Do not use the diseased plants for propagation. Disinfect, clean grafting tools. Orchard hygiene (removal of dead flower parts, leaves, and twigs) is done. Harvesting fruit in dry days, avoid bruising fruit. After harvesting can dip fruit in 0.1% Benlate (benomyl)or 0.55 mL/L Sportak (prochloraz).

SEED CAVITY BROWNING

Cause: Poor handling after harvest (picking, packing, marketing) or cool storage of fruit harvested from boron-deficient trees.

Symptoms: Damage appears as discrete brown areas in the seed cavity. Symptoms develop only at ripe.

Prevention: Apply borax to the ground under the tree or mixing it to water and spraying it on the ground. Handle fruit carefully. Avoiding drop fruit > 20cm for hard green fruit;> 5cm for sprung to ripe fruit.
