Not sure what this is , but out of 50+ fruit trees it’s only on my Santa Rosa plum. Trying to find out what I can do to combat the problem.
Thanks Tim

Looks like aphids. I don’t think it’s scale. The scale would likely be on the midrib and moving down the petiole.

If aphids you can ignore them this late in the yr.

Thanks Steve, I’ll ignore it for now but what should be used in the future to deal with them?

Make sure they are aphids. With a magnifying glass it’s pretty easy to tell. They come in many sizes and colors.

Most insecticides will work. Oil, insecticidal soap, or even a heavy stream of water can at least help some. At times when I’m summer pruning for height control I just cut off the new growth. I’ve been know to squish a few.
