Hi @Will01,

They appear to be hard-scale insects, so you might like to check out this article: How to get rid of scale insects. The mainstay of scale insect control is the application of horticultural oils. Oil sprays suffocate small insects such as scale Insects. I'd recommend you apply Multicrop 1L EcoPest Oil Insect Spray. As this is a hard scale, the spray won't remove the scale that is already on the fruit, but with continued use, it should help prevent future fruit from having the same issue. By the way, as long as the plant is healthy, this hard scale is really an aesthetic issue, and the fruit will be perfectly edible.

Let me tag a couple of our resident gardening experts, @Noelle and @mich1972, to get their thoughts.

Please let me know if you have any questions.
