Hops Pests/leaf discoloration #659257

Asked July 02, 2020, 11:39 PM EDT

I'm having a problem with the hops I transplanted this season. They appear to be infested with a pest and deteriorating as a result. The first image shows the discoloration. The second image shows the pest which I assume is the culprit, tiny, elongated almost transparent with multiple barely perceptible legs. Can you help identify and offer a treatment? Thanks, Phillip

I have included an article from OSU Extension that discusses hop production and references pests that can affect their growth and development.  Your crop may be infested with aphids and the article mentions ways to treat that issue.  Best of Luck, hope this helps.
