Woodhead and Chamberlain (1940), in a report of a survey of berry fruit carried out in 1940, noted that leaf spot of strawberries due to Mycosphaerella fragariae occurred throughout the country, especially in the Auckland district. They suggested regular applications of Bordeaux sprays for its control. Anon. (1951 b) reported that, of the 22 strawberry varieties tested for resistance to this fungus leaf spot, only four varieties were found to be resistant, 12 susceptible, and six highly susceptible; there appeared to be no strain difference in the different isolates of the fungus used in these tests. Nichols (1960) showed that this fungus attacked fruits as well as leaves to give a black discolouration of the seeds and small hard lesions in the fruit; he recommended for its control the removal of foliage from plants in the winter months, to be followed by regular sprays of captan.
