Notes

Downy mildew on brassica crops was reported from New Zealand by Kirk (1906) In some seasons it can be an important disease, especially in seedling beds. In cabbage and in cauliflower it may cause considerable discoloration of tissues of mature heads. Jafar (1963) reported an outbreak of downy mildew on stock plants; in the Auckland area it attacked seedlings and adult plants and stocks could no longer be grown as an early spring bedding plant; Jafar suggested that streptomycin sprays may be used for its control.
