Notes

In New Zealand Alternaria citri is recorded as causing scabbing and discolouration of fruit of new zealand grapefruit; it may be a primary pathogen on leaves of citronelle and may occur associated with an internal rot of sweet oranges. Copper sprays applied to control Phytophthora fruit rot will also control this fungus. It is of only minor economic importance in citrus in New Zealand.
