Descriptions
Phytophthora nicotianae Breda de Haan 1896
Black shank or black root rot of tobacco has up till the present been listed as due to Phytophthora parasitica. Waterhouse (1956) showed that P. nicotianae was the older name for this species. It is common in seedling beds as a black root rot (Anon., 1952a) and as a stem canker in mature tobacco plants in Nelson (Anon., 1953b). Tests for varietal susceptibility showed that 'Harrison's Special 215' and `Virginia Gold' were especially susceptible to the disease (Anon., 1956b).
It is recorded occasionally as a fruit rot of tomatoes. It has also been isolated from stem lesions on a 20-year-old tree of Agathis australis.
