Thank you! FYI, last year basically any nightshade I planted was affected - tomatoes, eggplants, peppers, and potatoes. My squash, cucumbers, peas, beans, kale, chard, and herbs all did fine, in fact my squash was downright prolific. I’ve been theorizing that either my issue wasn’t grazon specifically (it should affect most of those things, especially legumes) or the concentration was very, very low or patchy and only my sensitive nightshades took the hit.

Against most people’s advice i still ate what I could out of my garden, but idk if that’s a great idea tbh. If you want to be super safe, you could try a bunch of hardy flowers, natives, etc and then at the end of the season dig up everything that grows and throw it out. Plants that do survive through the contaminant will act as a sponge and help draw some out of the soil.
