Economic Impacts of Zebra Chip in Idaho, Oregon, and Washington
American Journal of Potato Research, 2018Zebra Chip disease vectored by the potato psyllid Bactericera cockerelli (Sulc) was first reported in Idaho and the Columbia Basin of Oregon and Washington in 2011. Since then growers have incurred significant costs for managing the disease. Thus, we conducted an expert opinion survey to estimate expenditure on insecticides dedicated to controlling ...

Evaluation of Zebra Chip Using Image Analysis
American Journal of Potato Research, 2020Candidatus Liberibacter solanacearum induced the disease known as zebra chip, manifested as an internal brown discoloration of potato tuber. This bacterium causes the vascular tissue of the tuber to turn brown, which shows up on potato chips after they have been fried, and which causes economic losses.

Susceptibility of Selected Potato Varieties to Zebra Chip Potato Disease
American Journal of Potato Research, 2011 Zebra chip (ZC), an emerging and serious disease of potato has caused millions of dollars in losses to the potato industry in the United States, Mexico, Central America, and New Zealand. The disease has recently been associated with a previously undescribed species of liberibacter tentatively named “Candidatus Liberibacter solanacearum” transmitted to ...

Hyperspectral imaging for identification of Zebra Chip disease in potatoes
Biosystems Engineering, 2020A Zebra Chip (ZC) disease detection system was developed based on hyperspectral imaging (HSI) to minimise economic losses in the New Zealand potato chip industry. Current detection methods for other than heavily diseased tubers require peeling or cutting of potato tubers.

Investigations on Putative Zebra Chip Tolerant Potato Selections
American Journal of Potato Research, 2015‘Candidatus Liberibacter solanacearum’ (Lso) has emerged as a devastating pathogen of solanaceous and other vegetable crops. In potato, Lso is the causative agent of zebra chip (ZC) disease, which threatens production in North and Central America and New Zealand.

Nondestructive detection of zebra chip disease in potatoes using near-infrared spectroscopy
Biosystems Engineering, 2018Near-Infrared (NIR) spectroscopy (900–2600 nm) was evaluated as a rapid, non-destructive method for detection of zebra chip disease (ZC) in potatoes. Two models were tested; one that directly correlated spectra with ZC and one that measured sugar concentrations which in turn are known to be correlated with ZC.

Candidatus Liberibacter solanacearum (zebra chip).
2021Abstract Candidatus Liberibacter solanacearum (Lso) is a phloem-limited, Gram-negative, unculturable bacterium that is primarily spread by psyllid insect vectors. It is considered very invasive due to its ability to be transported primarily in infective psyllids (Munyaneza et al., 2007a; 2010a,b; 2012a,b; Munyaneza, 2012; Alfaro ...

Phenotypic and Etiological Differences Between Psyllid Yellows and Zebra Chip Diseases of Potato
American Journal of Potato Research, 2009Both potato psyllid yellows and zebra chip (ZC) potato diseases are associated with the potato psyllid, Bactericera cockerelli (Sulc). Aboveground plant symptoms of both diseases are similar but there is a difference in symptoms in potato tubers. ZC has recently been associated with a new species of the bacterium liberibacter, ‘Candidatus Liberibacter ...

Zebra chip disease enhances respiration and oxidative stress of potato tubers (Solanum tuberosum L.)
Planta, 2017The physiological phenotype of potato tubers afflicted by zebra chip disease is characterized by increased oxidative stress metabolism and upregulation of systems for its mitigation. Starch catabolism and extensive buildup of reducing sugars render potatoes infected with zebra chip (ZC) pathogen (Candidatus Liberibacter solanacearum) unsuitable for ...

Use and Cost of Insecticides to Control Potato Psyllids and Zebra Chip on Potatoes
Southwestern Entomologist, 2012Abstract. Zebra chip disease has become a serious problem in North America. Data from growers in Kansas, Nebraska, and Texas enabled us to document insecticide use and costs to control zebra chip in 53 commercial fields of potato, Solanum tuberosum L. The number of different insecticides used in Texas decreased from 16 in 2009 to 10 in 2011.
