Psyllids test positive for Liberibacter in Idaho
Adult psyllids collected on June 19 from a commercial potato field in Twin Falls County have tested positive for Liberibacter, the bacterium that causes zebra chip.
Gene sequencing confirmed the Polymerase chain reaction (PCR) tests by Alex Karasev’s lab at the University of Idaho that identified the Liberibacter found in Twin Falls County.
Additional psyllids were collected last week from the same site and from the U of I Kimberly Research & Extension Center and are being tested for Liberibacter.
