Keeping an Eye OutThree years of monitoring potato psyl I ids, zebra chip in Idaho

摘要

Zebra chip disease, first discovered in the Pacific Northwest in 2011, causes discoloration of tubers that becomes more pronounced when tubers are cooked, especially as chips or fries. The disease is caused by the bacterium Candidatus Liberibacter solanacearum (Lso) and is transmitted by an insect called the potato psyllid. In 2012, we began monitoring commercial potato fields across Idaho for potato psyllids, Lso, and zebra chip. Over the following two years, our monitoring program expanded, each year covering roughly 90 to 100 fields across the potato-growing region of the state.
