Abstract
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. In May 2016, USDA Animal and Plant Health Inspection Service-Plant Protection and Quarantine (PPQ) confirmed the presence of the Asiatic A strain, which is by far the most widespread and severe form infecting most citrus varieties, on two sour orange trees in a park in Houston. Subsequently, infected trees were detected in a nursery in Richmond (Fort Bend Co.) in August 2016 and in dooryard trees in Pearland (Brazoria Co.) in 2018. PPQ and Texas Department of Agriculture collected a combined 1,949 positive A strain samples from Harris, Fort Bend, and Brazoria Counties during May 2016 to January 2021. These findings resulted in seven active citrus canker quarantine zones being established in the Upper Gulf Coast area. The Texas Department of Agriculture is removing positive trees, and surveys are continuing.
