Notes

Boucher (1912) recorded brown rot on citrus trees in New Zealand. Cunningham (1925a) described both a fruit rot and a stem canker caused by the fungus. Fletcher (1954) reported that in wet seasons infection can be severe in the Auckland area resulting in loss of all fruit on the trees; he recommended the application during winter months of copper sprays such as Bordeaux mixture. Fletcher (1957b) showed that when Poncirus trifoliata was used as a rootstock it was more resistant to the formation of stem cankers than sweet orange stock.

Phytophthora citrophthora (R.E. Sm. & E.H. Sm.) Leonian 1925

Description

Type: Radicicolous Fungi; Description: Colonies on agar with a characteristic finely radiate growth, aerial mycelium fluffy. Chlamydospores produced by some, but not all isolates, 25–35 μm in diameter. Sporangia mostly intercalary, very variable in shape and size, ranging from globose to ovoid to ellipsoidal to extremely distorted, often with two papillae, 25–90 × 18–60 μm. Oogonia, antheridia, and oospores not known.

Distribution

Distribution: Nelson, Marlborough Sounds.; 1st Record: Boucher (1912: as Pythiacytis citrophthora).

Notes

Pathogenicity

Significance: Of no significance in forestry. ‘Brown rot of citrus’ can cause serious losses. Use of resistant root-stock gives very good control (Atkinson 1971).; Host(s): Citrus grandis × reticulata, C. ichangensis × reticulata, C. limon, C. sinensis, Nothofagus fusca, Poncirus trifoliata.
