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
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.
