Crop Protection, 2020 Abstract Asiatic citrus canker (ACC, caused by Xanthomonas citri subsp. citri, [Xcc]) is a serious disease of citrus, reducing yield and impacting marketability of fresh fruit. ACC has phytosanitary implications for fresh fruit trade. Lesions on fruit, leaves, and shoots in an orchard of ACC-susceptible grapefruit were monitored for production of Xcc

Abstract Citriculture in Sao Paulo State, Brazil, is threatened by Asiatic citrus canker (Xanthomonas axonopodis pv. citri). The introduction of the Asian citrus leaf miner (Phyllocnistis citrella [CLM]) has resulted in an increase in the number of disease foci and has changed the spatial pattern of citrus canker symptomatic trees from strong ...

Australasian Plant Pathology, 1995
In May 1993, symptoms of asiatic citrus canker were found on West Indian lime, lemon and grapefruit trees in a mixed citrus orchard at Lambell’s Lagoon, near Darwin, Northern Territory, close to the site of a previous (1991) canker outbreak. Symptoms occurred on the spring growth flush at the start of the wet season (October 1992). The time lag between

The combined effect of temperature (15°C, 20°C, 25°C, 30°C, 35°C, 40°C and 42°C) and leaf wetness duration (0, 4, 8 12, 16, 20 and 24 h) on infection and development of Asiatic citrus canker (Xanthomonas citri subsp. citri) on Tahiti lime plant was examined in growth chambers. No disease developed at 42°C and zero hours of leaf wetness. Periods of leaf

Analysis of Foci of Asiatic Citrus Canker in a Florida Citrus Orchard
Plant Disease, 1992In October 1990, the occurrence of Asiatic citrus canker in an orchard in south Florida was apparently related to spread of Xanthomonas campestris pv. citri from dooryard trees 230 m away on an adjacent property. The establishment of apparent initial foci of disease in the orchard coincided temporally with a major rainstorm with high winds during mid ...

Bacterial Exudation from Lesions of Asiatic Citrus Canker and Citrus Bacterial Spot
Plant Disease, 1991When water was added to wells surrounding young lesions of Asiatic citrus canker (caused by Xanthomonas campestris pv. citri) on detached, field-collected leaves of grapefruit, about 10 4 -10 5 bacteria per milliliter were exuded immediately. Bacterial exudation into the water continued at high levels for 24 hr, and cumulative release ranged from 10 5

First Report of Xanthomonas citri pv. citri Pathotype A Causing Asiatic Citrus Canker in Madagascar [PDF]
Plant DiseaseAsiatic citrus canker (ACC), caused by Xanthomonas citri pv. citri, is a threat to citrus industries worldwide. X. citri pv. citri is delineated into three pathotypes differing in pathogenicity towards Citrus species and hybrids. The pathogen negatively impacts production in tropical and subtropical areas, resulting in direct losses (yield decrease due

Asiatic Citrus Canker Detected in a Pummelo Orchard in Northern Australia
Plant Disease, 1992Raised, roughly circular, corky scabs 4-5 mm in diameter and typical of citrus canker were observed on spring flush leaves, twigs, and fruits of pummelos (Citrus grandis) in a young orchard near Darwin, Australia, during a survey conducted in 1991 as part of the Northern Australia Quarantine Strategy.
