New Preharvest Treatments and Strategies in Managing Phytophthora Brown Rot of Citrus in California
Plant Disease, 2023Brown rot caused by Phytophthora citrophthora, P. nicotianae, P. syringae, and P. hibernalis is an important fruit disease of citrus in California, and the latter two species are quarantine pathogens in some important export markets. The newly registered fungicides oxathiapiprolin (OXA) and mandipropamid (MAN), as well as a premixture of the two (MAN +

Postharvest Strategies for Managing Phytophthora Brown Rot of Citrus using Potassium Phosphite in Combination with Heat Treatments [PDF]
Phytophthora brown rot, caused by several species of Phytophthora, is an economically important disease of citrus in areas with rainfall during the late stages of fruit development. Recent export restrictions of California orange fruit to China due to the presence of brown rot caused by the quarantine pathogen Phytophthora syringae have mandated more ...

Control of phytophthora brown rot of citrus fruits1
EPPO Bulletin, 1990Control of brown rot of citrus fruits, using the new anti‐oomycete systemic fungicides, has been studied in the field and in packing houses under the climate conditions of Spain. In the field, in rainy weather and at the stage of colour‐break of the fruits, both with artificial inoculation and with natural infection by Phytophthora citrophthora, a ...

Phytophthora Brown Rot of Citrus: Temperature and Moisture Effects on Infection, Sporangium Production, and Dispersal [PDF]
Sporadic epidemics of Phytophthora brown rot occur in citrus orchards in Florida and are caused primarily by Phytophthora palmivora and secondarily by P. nicotianae. With P. palmivora, fruit wetness durations of 3 h or more resulted in maximum infection at favorable temperatures.

FIRST REPORT OF CURVULARIA SPICIFERA CAUSING BROWN ROT OF CITRUS IN SOUTHERN IT
Journal of Plant Pathology, 2015In 2014, rot symptoms were observed on mandarin fruits (Citrus reticulata) in a grove of Metaponto (southern Italy). Five to 7 mm lesions, colonized by a brown mycelium characterized diseased tissues. Fruit was collected, and surface-sterilized in 2% sodium hypochlorite.

First report of Phytophthora palmivora as a causal pathogen of citrus brown rot in Japan
Journal of General Plant Pathology, 2012A fruit rot, similar to brown rot, occurred on extremely early ripening Satsumas in Saga Prefecture in the early autumn of 1999. A single species of Phytophthora was isolated from the affected fruit. After nonwounding inoculation of healthy fruits of Citrus spp.

Supplementary Antimold Activity of Phosethyl AL, A New Brown Rot Fungicide for Citrus Fruits
Journal of Phytopathology, 1983AbstractPhosethyl Al (= Aliette) is a new and promising postharvest fungicide against brown rot of citrus fruits. Its effectiveness in controlling green mold (Penicillium digitaum), the major citrus fruit pathogen, was studied on artificially inoculated fruit and compared with that of sodium o‐phenylphenate (SOPP) and thiabendazole (TBZ).

Phytophthora citrophthora, P. syringae, P. nicotianae, and less commonly P. hibernalis are causal agents of brown rot of citrus fruit in California. The chronic disease occurs during the winter season, requires annual management, and has limited California citrus exports because of quarantines in some markets.

Control of brown rot of citrus fruit by application of fungicides via sprinkler irrigation systems
Phytoparasitica, 1978Copper fungicides applied via low head sprinklers, reduced brown rot (caused byPhytophthora spp.) on oranges and grapefruit. The most effective fungicide was Bordeaux mixture, which reduced the disease rate to the same level as that obtained by standard spraying with this fungicide. Copper oxychloride was moderately effective and captan was ineffective.
