Spots on tomatoes

Asked September 26, 2020, 8:55 PM EDT

We have had a very successful tomato harvest this year. Today I noticed some green spots on our ripening tomatoes, that turn tan once ripened, I attached 3 pictures. Our soil was poor, and we supplemented with liquid fertilizer all season, Tiger Bloom. The closest disease I could find was bacterial canker, but it doesn't match completely. Any ideas? Are they safe to eat? Thank you.

Thank you for your question. Your plants appear to have bacterial leaf spot, rather than bacterial canker. Here is the OSU Diagnostic guide describing it, as well as cultural mechanisms to control it: https://pnwhandbooks.org/plantdisease/host-disease/tomato-solanum-lycopersicum-bacterial-spot Although some of the chemical treatments are organic (O), none are available for homeowners (H). Cultural control is your best bet. Good luck!

Thank you for your help. Are the tomatoes without spots from the plant safe to eat? I have probably 30 lbs of tomatoes I would be so sad to have to trash.

I am not trained in food safety. However, here is an Extension article that recommends that fruit with spots not be eaten: https://hort.extension.wisc.edu/articles/bacterial-spot-of-tomato/ I am sorry.
