Tiny spots on leaves

Tomatovator · August 15, 2006

Any ideas as to what is going on with my tomato leaves? There are tiny spots or specks that look silvery or metalic in the sun forming on a lot of the leaves. The leaves that are affected look like they have been peppered. I don't see any insects on the plants. I see no aphids. It just started about 2 weeks ago and seems to be scattered on all of my 8 plants. They are Beefsteak, Rutgers and Big Beef. It is not only appearing on some lower leaves but in the middle and at the top as well. I do spray with Daconil and during the Spring sprayed with Bonide Eight as I had a lot of aphids. I looked at several of the diagnostic websites but didn't see anything that looked similiar. I did take pictures but I have no idea how to post them. Any help would be appreciated.

Without a picture, it sure is hard to try and make a diagnosis. Frankly, even with a picture, it can be difficult.

In order to post pictures, they have to be hosted first.

Free hosting sites would include--

Then, this topic explains how to post the hosted photos--

If done correctly, "You should see the actual image show up in your post when you preview it."

From what you've described, you might want to have a look at images of septoria leaf spot or bacterial spot as possibilities. A Google Images search can be helpful in that it will show you several different pictures and not just one or two like the TAMU problem solver and other links might.

Thanks Suze, Looks like it could be septoria leaf spot. I've been spraying Daconil with no effect on it. I guess I'll have to try copper? What do you think?
