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 Idaho

Citation
Crosslin et al. (2012). Plant Disease 96 (3)
Names
“Liberibacter solanacearum”
Abstract
In September 2011, potato (Solanum tuberosum L.) tubers graded in a packing facility in south-central Idaho were observed with internal discolorations suggestive of zebra chip disease (ZC). Symptoms were observed in 1 to 2% of tubers of cv. Russet Norkotah and included brown spots and streaks especially in and near the vascular tissue. Some tubers also showed a dark and sunken stolon attachment typical of ZC (1). Initially, tissue samples were taken from seven symptomatic tubers and tested by P

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

Citation
Crosslin et al. (2012). Plant Disease 96 (3)
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
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% 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
