Summary

​Zebra chip, a new and damaging disease of potato is causing millions of dollars in losses to the potato industry in the United States, Mexico, Central America, and New Zealand. The disease is associated with a new species of the bacterium Liberibacter, which is transmitted to potato by the potato psyllid. This presentation will help consultants, growers, and other practitioners in affected areas recognize zebra chip symptoms and understand the disease epidemiology, the biology and behavior of the potato psyllid, and ways to control this insect pest to effectively manage zebra chip.
