Expert Response
Aphid infestation.
Aphid populations tend to be higher in crops that are fertilized liberally with nitrogen. Home gardeners can often get effective control by washing aphids with a strong stream of water.
I would also refer you to the aphid management in vegetable crops and particularly the insecticidal soaps or oils in-home use section https://pnwhandbooks.org/insect/vegetable/vegetable-pests/hosts-pests/chard-swiss-aphid
