Plywood may contain/be treated with copper azole. You can learn more about this here: https://www.extension.iastate.edu/smallfarms/toxicity-concerns-about-raised-bed-construction-materials Particle board is not mentioned on that page but we would avoid it. As for the bug spray you need to read the can/container; usually there are advisories on such products. Without knowing what chemicals it contains, we would only be guessing. That said, we would propose that you might be able to transplant the kale and berries. Hard to know how far along they are but if you get a new, safe, clean plot ready and get it done and then provide lots of TLC, you might have a harvest after all. We hope this helps.
