- Phytophthora citrophthora, also known as brown rot of citrus, is a soil borne oomycete that infects several economically important citrus crops. A diagnostic symptom of P. citrophthora is gummosis, wherein lesions around the base of the tree exude sap. Other common symptoms include dark longitudinal lesions forming at the soil line, a sour smell, and eventual cracking of the bark. Advanced symptoms include yellowing and necrosis of the tree canopy. Girdling action caused by the pathogen around the trunk can often cause the collapse of the tree. Resistant lemon varieties have been developed and their implementation has been effective at controlling the spread of the disease. Fruits that have been infected with P. citrophthora exhibit symptoms of brown rot characterized by a distinct odor. This disease is most active in the moderate temperatures of spring, fall, and winter months, opposite of most other Phytophthora species. (en)
- Phytophthora citrophthora est une espèce d'oomycètes de la famille des Peronosporaceae à répartition cosmopolite. C'est un agent phytopathogène qui attaque de nombreuses espèces de plantes, notamment les agrumes chez lesquels il provoque diverses maladies : gommose, mildiou, pourriture brune des agrumes. (fr)
- La Phytophthora citrophthora (R.E. Sm. & E.H. Sm.) Leonian, 1906 è un patogeno delle piante appartenente agli Oomycota e attacca gli agrumi causando marciumi al colletto e alle radici delle piante e marciumi ai frutti. Sugli agrumi i marciumi al colletto possono essere causati anche da altre specie del genere Phytophthora, come o , ma la Phytophthora citrophthora è quella che provoca i maggiori danni. La scoperta di questo patogeno ha determinato l'iniziale interesse verso l'utilizzo del portinnesto in agrumicoltura. Si è progressivamente abbandonato l'utilizzo di piante ottenute da seme per passare alla propagazione mediante utilizzo di portinnesti resistenti a questa patologia come l'arancio amaro (Citrus × aurantium).
