Black ring

Planted a very late garden. Only a couple of tomato plants "took". The first tomato fruits are about half grown. These two have developed a black ring on the fruit about one inch from the stem. What is this, and is it a concern?

Okay, no matches. Closest written description I've found was due to excessive sun. Leaves are hiding the fruit well enough though. Leaves showing signs of verticillium wilt.

Biology Tomato anthracnose is a fungal disease primarily seen on ripe fruit. It may sometimes affect leaves. Leaf symptoms are most common on older leaves, which show small, dark spots surrounded by a yellow halo. Fruits may be infected while green, but symptoms are seen on ripe fruit. Infected fruits initially show circular, sunken, water-soaked spots. The spots enlarge to about 1/2" in diameter and become darker. They often show concentric ring markings around a tan center. Dark specks may be present on the tan area. During damp weather, masses of salmon-colored spores may develop on the surface of the lesion. The fungus frequently overwinters on diseased plant debris and can also infect other crop and weed species. Wet soils favor disease development.
Management Options Select Non-chemical Management Options as Your First Choice!!
* Avoid overhead irrigation. * Control weeds in and around the garden. * Plant in well-drained soils. * Remove plant debris from the garden. Destroy or discard (do not compost) diseased plant materials. * Rotate crops on a three- to four-year cycle to avoid fungus surviving in the soil. Do not plant tomatoes in the same location each year.
