Citrus Canker

Impact. Citrus canker normally causes leaf-spotting and fruit rind-blemishing, although when conditions are highly favorable for infection, citrus canker can cause defoliation, shoot dieback, and fruit drop. Marketability of symptomatic fresh fruit is negatively impacted. Citrus canker is harmless to humans and other animals.
Biology of citrus canker. Citrus canker bacteria are spread by wind, splashing water, movement of infected plant material, or mechanical contamination. The pathogen flourishes under moist and warm conditions. Citrus canker bacteria require a susceptible hostplant to grow in nature, although it can persist in cracks in bark for years. The bacteria can enter the tissues of susceptible citrus varieties through leaf pores (stomata) and through wounds such as those caused by leaf miners. Distribution of the disease in an infected plant is restricted to the localized sites of infection, since the bacteria can not spread systemically through the tree. Seven to 10 days following entry of the bacteria into a host leaf, a pinpoint lesion becomes visible. Young lesions on leaves are raised or ‘pustular’ on both leaf surfaces, but particularly on the lower surface. Leaf pustules characteristically develop a yellow halo with water-soaked margins, becoming corky and crateriform, with a raised margin and sunken center. Leaf lesions eventually can attain 2-10 mm diameter. Leaves and young green stems are vulnerable to infection. Lesions persist but new lesions are not initiated on brown hardened stems.

Quarantined Area Descriptions

Greater Houston Quarantined Areas

Friendswood Quarantined Area.
On July 28, 2021, a residential citrus tree in Friendswood, Texas was found to be infected with citrus canker. Laboratory analysis determined the pathotype as Xac A (i.e. Asiatic or A strain). TDA has quarantined the area and is working in collaboration with the USDA, the citrus industry, and residents to destroy all infected plants and combat this destructive citrus disease. All varieties of citrus and other quarantined articles inside the quarantined area are subject to the quarantine restrictions and requirements.

Richmond Quarantined Area.
Citrus nursery trees at a retail nursery in Richmond, Fort Bend County, Texas, were routinely inspected by TDA on July 28, 2016. Some of the trees were found to be symptomatic for citrus canker; whereupon, TDA collected samples, placed the trees under seizure, and rushed the samples to USDA for identification. USDA immediately screened then sent the samples off for laboratory confirmation, which confirmed the trees were infected with citrus canker. TDA inspection determined that most of the approximately 300 citrus nursery trees at the retail nursery were infected with citrus canker. With the nursery’s consent, TDA destroyed all the symptomatic and the suspect citrus nursery trees and disposed of them according to sanitation procedures, to prevent accidental spread of the disease. USDA began survey work to identify all infected plants in the area and to determine how far the infestation extended in all directions. On August 10, 2016 TDA established the Richmond Citrus Canker Quarantined Area, in collaboration with USDA-APHIS-PPQ. Inspection of plants, their labels and nursery purchase records, disclosed that the nursery’s multiple varieties of infected citrus trees were from four propagative nurseries in Texas. All nurseries that had sold citrus plants to the retail nursery were thoroughly inspected and found to be free of citrus canker. The citrus nursery plants must have become infected after they had arrived at the retail nursery in Richmond. Currently there are no commercial producers of citrus fruit and no producers or retailers of citrus nursery trees inside the quarantined area. Only dooryard (ornamental/personal use) citrus trees are found inside the quarantined area. To combat the infestation, as soon as USDA locates a citrus canker infected tree, TDA inspectors seek homeowner cooperation, then destroy and sanitarily dispose of the tree. All varieties of citrus and other quarantined articles inside the quarantined area are subject to the quarantine restrictions and requirements.

Pearland Quarantined Area.
On May 18, 2018, a residential citrus tree in Pearland, Texas was found to be infected with citrus canker. A delimiting survey around the positive tree revealed the extent of the infestation, resulting in 22 additional citrus trees found to be infected with citrus canker. TDA has quarantined the infested area and is working in collaboration with the USDA, the citrus industry, and residents to destroy all infected plants and combat this destructive citrus disease.  All varieties of citrus and other quarantined articles inside the quarantined area are subject to the quarantine restrictions and requirements.

Silver Lake Quarantined Area.
On July 20, 2020, a residential citrus tree west of Pearland, Texas was found to be infected with citrus canker. Laboratory analysis determined the pathotype as Xac A (i.e. Asiatic or A strain).

TDA has quarantined the infested area and is working in collaboration with the USDA, the citrus industry, and residents to destroy all infected plants and combat this destructive citrus disease.  All varieties of citrus and other quarantined articles inside the quarantined area are subject to the quarantine restrictions and requirements.

All varieties of citrus and other quarantined articles inside the quarantined area are subject to the quarantine restrictions and requirements.

West Houston Quarantined Area.
On January 21st, 2021, a residential citrus tree west of Houston, Texas was determined to be infected with citrus canker.

In November 2021, TDA found 17 infected potted citruses at a citrus foliage nursery in Rosharon, Brazoria County. This find was 11 miles south of the existing South Fork quarantine. Samples were collected and sent for Laboratory Analysis. The sample results confirmed positive results for citrus canker. Laboratory analysis determined the pathotype as Xac A (i.e. Asiatic or A strain). A delimiting survey was conducted and revealed additional infected citrus in the area. TDA has quarantined the infested area and is working in collaboration with the USDA, the citrus industry, and residents to destroy all infected plants and combat this destructive citrus disease.

Only kaffir lime, key lime and one Ponderosa lemon tree (with heavy leaf miner damage to the infected leaves) in the Rancho Viejo area have been confirmed by USDA for citrus canker. The field observations and research indicate that the strain of citrus canker found in the Rancho Viejo Citrus Canker Quarantined Area only infects lime and lemon trees. The pathogen is likely the Wellington or W strain.All varieties of citrus and other quarantined articles inside the quarantined area are subject to the quarantine restrictions and requirements.
