Citation
Munyaneza et al. (2012). Plant Disease 96 (3)
Names
“Liberibacter solanacearum”
Abstract
Carrot (Daucus carota) plants with symptoms resembling those associated with the carrot psyllid Trioza apicalis and the bacterium “Candidatus Liberibacter solanacearum” (1–4) were observed in 70 to 80% of commercial fields and experimental plots in southeastern Norway from late July to mid-September of 2011; all cultivars grown were affected with approximately 10 to 100% symptomatic plants per field. T. apicalis, a pest of carrot in northern and central Europe, including Norway, can cause as mu

First Report of Zebra Chip Disease and “Candidatus Liberibacter solanacearum” on Potatoes in Oregon and Washington State

Citation

Names
“Liberibacter solanacearum”
Abstract
In August of 2011, potato (Solanum tuberosum) tubers grown in the lower Columbia Basin of southern Washington State and northern Oregon were observed with internal discolorations suggestive of zebra chip disease (ZC). Symptoms included brown spots, streaks, and stripes in and near the vascular tissue, typical of ZC (1). Symptoms were observed in cvs. Alturas, Russet Norkotah, Pike, Ranger Russet, Umatilla Russet, and Russet Burbank. Foliar symptoms on plants that produced symptomatic tubers inc

First Report of “Candidatus Liberibacter solanacearum” Associated with Psyllid-Affected Carrots in Sweden

Citation

Names
“Liberibacter solanacearum”
Abstract
Carrot (Daucus carota) plants with symptoms resembling those associated with the carrot psyllid Trioza apicalis and the bacterium “Candidatus Liberibacter solanacearum” (1–4) were observed in 70% of commercial fields in southern Sweden in August 2011, with approximately 1 to 45% symptomatic plants per field. T. apicalis, a pest of carrot in northern and central Europe, including Sweden, can cause as much as 100% crop loss and is associated with “Ca. L. solanacearum” (1–4). Symptoms on affected

First Report of “Candidatus Liberibacter solanacearum” Associated with Psyllid-Affected Carrots in Europe

Citation

Names
“Liberibacter solanacearum”
Abstract
Carrot (Daucus carota) plants with symptoms resembling those of carrot psyllid (Trioza apicalis) damage (3,4) were observed in 14 commercial fields in southern Finland in August 2008; all cultivars grown were affected at approximately 5 to 35% symptomatic plants per field. T. apicalis, a pest of carrots in northern and central Europe, can cause up to 100% crop loss (3,4). Symptoms on affected plants included leaf curling, yellow and purple discoloration of leaves, stunted growth of shoots and r

First Report of “Candidatus Liberibacter solanacearum” in Tomato Plants in México

Citation

Names
“Liberibacter solanacearum”
Abstract
Tomato (Solanum lycopersicum) plants exhibiting symptoms resembling those of permanent yellowing disease (known in Mexico as “permanente del tomate”) that is commonly associated with phytoplasmas (1) were observed in tomato fields in Sinaloa, México in March 2009. Plant symptoms also resembled those caused by “Candidatus Liberibacter solanacearum” infection (2). Affected plants showed an overall chlorosis, severe stunting, leaf cupping, purple discoloration of veins, excessive branching of axil

First Report of “Candidatus Liberibacter solanacearum” in Pepper Plants in México

Citation
Munyaneza et al. (2009). Plant Disease 93 (10)
Names
“Liberibacter solanacearum”
Abstract
Bell pepper (Capsicum annuum) plants exhibiting symptoms that resembled those of potato psyllid (Bactericera cockerelli Sulc) damage and “Candidatus Liberibacter solanacearum” infection (2) were observed in a pepper field in La Cruz de Elota, Sinaloa, México in March 2009, with an infection rate of 1.5%. Plants exhibited chlorotic or pale green apical growth and leaf cupping, sharp tapering of the leaf apex, shortened internodes, and an overall stunting (2). Total DNA was extracted from the top

First Report of ‘Candidatus Liberibacter psyllaurous’ in Potato Tubers with Zebra Chip Disease in Mexico

Citation

Names
Ca. Liberibacter psyllaurous
Abstract
Zebra Chip (ZC), an emerging disease of potato (Solanum tuberosum L.) first documented in potato fields around Saltillo in México in 1994, has been identified in the southwestern United States, México, and Central America and is causing losses of millions of dollars to the potato industry (4). Recently, this damaging potato disease was also documented in New Zealand (3). This disease is characterized by a striped pattern of necrosis in tubers produced on infected plants, and fried chips process
