View all images of my poor, sad potatoes
We got a couple successive spells of hot, dry weather in early July (interspersed with some rain and low-80s temps) and my potatoes kind of keeled over. At first, I just thought it was just the end of the cycle for the taters…they’d bloomed, blossoms faded, and plants started to die back.
Then I noticed kind of slimy “lesions” on some stems yesterday, and started to panic about blight. The plants aren’t significantly worse than yesterday; in fact, the sliminess of the lesions has dried to dry, dead spots on the stems – mostly tan, but some black. Below the dead sections, the plants are sprouting new healthy growth. Black dot, verticilium wilt, and fusarium wilt are my prime suspects.
The spots on the leaves are brown and crispy, and they’ve been that way for a couple weeks. I’m wondering if that might be leafhopper damage; you can see even the “healthy” leaves have a lot of holes chewed in them.
So, all you Nightshade Ninjas…what’s going on here? Can I at least rule out blight?
