University of Idaho extension entomologist Erik Wenninger reported via PNWPestAlert.net that one potato psyllid collected last week from a yellow sticky card deployed at the Kimberly Research & Extension Center tested positive for Lso (liberibacter), the bacterium associated with zebra chip disease. No psyllids collected from commercial fields tested positive.
"We continue to urge growers and crop consultants to implement IPM programs for zebra chip," says Wenninger.
