Evaluation of Zebra Chip Using Image Analysis

American Journal of Potato Research, 2020
Candidatus 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.

Hyperspectral imaging for identification of Zebra Chip disease in potatoes

Biosystems Engineering, 2020
A 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, 2018
Near-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).

2021
Abstract 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 ...

Use and Cost of Insecticides to Control Potato Psyllids and Zebra Chip on Potatoes

Southwestern Entomologist, 2012
Abstract. 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.

Phenotypic and Etiological Differences Between Psyllid Yellows and Zebra Chip Diseases of Potato

American Journal of Potato Research, 2009
Both 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 ...

Differences in Zebra Chip Severity between ‘Candidatus Liberibacter Solanacearum’ Haplotypes in Texas

American Journal of Potato Research, 2018
‘Candidatus Liberibacter solanacearum’ (Lso) is a phloem-restricted plant pathogen that is vectored between host plants by the potato psyllid, Bactericera cockerelli. Lso infects solanaceous crops whithin North America and New Zealand and is responsible for causing zebra chip (ZC) in potato.

LC-MS Analysis of Phenolic Compounds in Tubers Showing Zebra Chip Symptoms

American Journal of Potato Research, 2009
A new potato disorder called Zebra Chip (ZC) has been identified in the United States and has been especially problematic in Texas, where substantial economic losses have been incurred. Upon frying, ZC tubers develop a dark “zebra” pattern of discoloration.

Zebra chip disease enhances respiration and oxidative stress of potato tubers (Solanum tuberosum L.)

Planta, 2017
The 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 ...
