I suspect that you have two different insect pests actively feeding on your artichoke plants. Without photos I will take an educated guess of whitefly and armyworm moth larvae.
Here is an example of a "ready to use" insecticidal soap product that will knock down both pests on contact and have a few days of residual effectiveness:

Insecticidal soap is organic program compatible because it can be washed off the edible vegetable and it biodegrades in a week or two. But it can burn skin and eyes, so read and follow directions for personal protection during application.
