Pests and diseases (18)
Problems recorded for this plant, most serious first.
Fusarium Wilt
Disease
Lower leaves wilt during the day and recover morning and evening, and this cycle repeats as the plant dies back. Cutting the stem reveals characteristic browning of the vascular tissue.
Powdery Mildew
Disease
White patches appear scattered on the upper leaf surface at first, then the whole leaf is coated in a white powder. Leaves later yellow, brown and die back, and reduced photosynthesis cuts growth and yield.
Anthracnose
Disease
Light brown to dark brown round lesions with sharp margins form on leaves and fruit, slightly sunken in the center. In wet weather salmon-pink slimy spore masses ooze out on the lesions.
Root Rot
Disease
Fine roots rot brown to blackish brown, growth stops and the lower leaves yellow. The plant wilts easily in the daytime and eventually dies outright.
Bacterial Spot
Disease
Small water-soaked spots appear on the leaves, later turning brown with yellowing around them. Fruit develops water-soaked or scabby spots from which rot spreads.
Violet Root Rot
Disease
The tree gradually loses vigor and the leaves shrink, sometimes wilting abruptly in summer. A purple-brown or white mycelial mat covers the root surface and the bark peels away easily.
