Modelling the progress of Asiatic citrus canker on Tahiti lime in relation to temperature and leaf wetness

open access: yesEuropean Journal of Plant Pathology, 2008
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

The Return of Asiatic Citrus Canker to Texas: Surveys and Eradication Efforts

Plant Health Progress, 2021
Citrus canker caused by Xanthomonas citri subsp. citri (syn. X. axonopodis pv. citri) was first reported in South Texas during the early 1900s, prompting quarantine and eradication programs by the federal government. Its last reported incidence in Texas was from two trees from Corpus Christi in 1943.

The Effect of Irrigation Practices on the Spatio-temporal Increase of Asiatic Citrus Canker in Simulated Nursery Plots in Reunion Island

open access: yesEuropean Journal of Plant Pathology, 1999
Asiatic citrus canker is a potentially severe disease of several citrus species and cultivars in many tropical and subtropical areas. In such areas, infected nursery plants constitute an important source of primary inoculum for newly established citrus groves.

First Report of Xanthomonas citri pv. citri Pathotype A Causing Asiatic Citrus Canker in Madagascar [PDF]

open access: yesPlant Disease
Asiatic 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

Effect of citrus leaf-miner damage, mechanical damage and inoculum concentration on severity of symptoms of Asiatic citrus canker in Tahiti lime

Crop Protection, 2007
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 ...

Re-occurrence of Asiatic citrus canker in the Makkah Province of Saudi Arabia and characterization of the causal agent Xanthomonas citri pv. citri isolated from Mexican lime

open access: yesJournal of Plant Pathology, 2023
Asiatic citrus canker (ACC) caused by Xanthomonas citri pv. citri (Xcc) is a destructive disease of citrus crops, worldwide. Typical ACC symptoms were observed on Mexican lime trees in the Makkah Province, Saudi Arabia, where the disease had been thought to be eradicated after its first occurrence in the late 1980ies.

Rapid Identification of a Second Outbreak of Asiatic Citrus Canker in the Northern Territory Using the Polymerase Chain Reaction and Genomic Fingerprinting.

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
