Green peach aphids were observed in Rupert/Burley this week. Aphids on potato are of concern only in regard to their transmission of plant viruses. Systemic insecticides are generally the most effective against aphids; however, use of insecticides may reduce, but will not eliminate spread of viruses. There are no well-established treatment thresholds for aphids in potato.
