A new potato alert was posted to PNWPestAlert.net.

"A recent submission of potato tuber samples grown in Power County were verified to be positive for Lso (Candidatus Liberibacter solanacearum), the bacterium causing zebra chip in potatoes. Symptoms of zebra chip include necrotic flecking in the flesh of the tuber, similar to net necrosis, but the symptoms extend throughout the length of the tuber. When diseased tuber tissues are fried, severe darkening in both chips and fries are seen. Because symptoms can be seen in uncooked tissues, the disease is a concern for both fresh and process potatoes. The No. 1 means to control zebra chip is to control infected potato psyllids. Non-infected psyllids will not cause zebra chip."
