Safety of canning tomatoes from plants with powdery mildew #879095
Asked July 28, 2024, 10:54 AM EDT
I couldn't find a food preservation group so this was the closest. My roma tomatoes plants have powdery mildew on the stems that has spread to some leaves. I had planned to can these tomatoes. Is that still safe to do? The fruit looks healthy.

I am sorry your plants have this substance on them. I am not a plant specialist and suggest you contact your local extension office horticulture specialist or garden specialist to take a sample of the plant for identification and treatment options.
As a general rule, only produce harvested at peak of ripening and from healthy plants should be processed for home canning. Any plant disease can affect the produce by changing the cell structure and/or taste and therefore safety. I also guide community members to ere on the side of caution, so I recommend not using these tomatoes for home canning.
