Black spot or grape anthracnose was first recorded by Kirk (1895) from Hawke's Bay. Only the conidial form has been found in New Zealand. Lindeman (1940) and Berry-Smith (1952; 1965) recorded it as a common disease on outdoor crops in all grape-growing districts. Early application of thiram or ziram has been noted as giving good control of the disease (Anon. 1956a). Berry-Smith (1965) stated that black spot may be controlled by the use of lime sulphur as a winter dormancy spray, followed by alternate sprays of thiram and copper oxychloride during the growing season.
