Whats wrong with these tomatoes? Pic included

zobot2000July 22, 2010

Hey garden community!

This is my first season growing tomatoes, and I'm so devastated. As you can see from the pics, something is eating away at the tomatoes. Most of the time they are big plump and green, and then when they start ripening, something starts "eating" (not an animal) them at the bottom, sides top, wherever.

We thought it was a fungus..and brokenheartedly bought some fungicide to spray on the previously organic tomatoes. So far, the fungicide hasn't done anything.

At this point, we'll try anything...just don't want to have wasted all that time and money and not actually be able to eat ANY of our tomatoes.

Any help is appreciated.

Slugs usually are messier than that. 2nd from right looks like bird damage.

Definitely not a fungus. Something is chewing.

The one on the far right looks like some wound was made, then opportunistic molds or yeasts came in to start rotting the fruit from the wound. The second from the right does look like birds, and the second from the left looks like some other creature (mouse? caterpillar?) ate away at it. I can barely see anything wrong with the one in the middle, but it shares a bunch of dark spots on the skin with almost all the others.

Those spots, along with the tomato on the left, make me think about anthracnose. It's a fungus which overwinters on debris and in soil, which is spread by splashing water and encouraged by wetness. It has a wide range of temperatures it can infect in, and it'll affect red or green fruit.

Anthracnose can be managed by some of the same methods we recommend for taking care of early blight: clean up all tomato debris in the fall, mulch heavily in the spring, pick off diseased leaves, don't overhead irrigate (I know, you can't stop the rain :) ) and spray regularly with a fungicide such as Daconil. Rotation doesn't do much in a small yard, as the spores are airborne.

I hope that helps somewhat -- though you still need to figure out a solution for the animal pests. :)
