Phytophthora cryptogea Pethybr. & Laff. 1919

Phytophthora cryptogea was first reported from New Zealand causing a basal rot of tomato seedlings from Auckland and Timaru (Brier, 1940c). It also occurred as a basal rot of seedlings of some bedding annuals. Robinson (1957b) recorded it as the cause of a basal crown rot of Gerbera sp. .Jacks (1951 b) suggested that it could be controlled with soil drenches of copper oxychloride; more recently captan has been used as a soil drench and has proved most satisfactory.

Type: Radicicolous Fungi; Description: Colonies on agar uniform, aerial mycelium fluffy; mycelium in water culture develops groups of angular swellings, 11–20 μm in diameter. Chlamydospores not known. Sporangia ovoid to obpyriform, 20–93 × 15–50 μm, non-papillate. Oogonia produced when cultured with a compatible strain or with P. cinnamomi, globose, 28–40 μm in diameter, smooth, becoming yellow with age. Antheridia amphigynous, globose. Oospores plerotic or nearly so, 20–32 μm in diameter.
Distribution: Northland, Auckland, Taranaki, Marlborough, Mid Canterbury.; 1st Record: Brien (1939).
Significance: Minor. Reported as the cause of seedling root rot in Agathis australis and Pinus radiata (Newhook 1959).; Host(s): Acmena smithii, Actinidia deliciosa, Agathis australis, Cyphomandra betacea, Leucadendron salignum, Pinus radiata, Prunus persica, Rubus idaeus, Solanum aviculare.
