What is this blight - see picture
 

Folks I have 16 Big Beef tomato plants that are producing some nice tomatoes however today when I went out I discovered that all of the lower branches on most of the plants had yellowing leaves with brown spots. See this picture (Enlarge the picuture to 100% afrter you open it)

Can someone tell me what this is and how should I treat it to stop it before it destroys my plants.

Thanks,

Paul

Hi, Paul. Welcome to Tomatoville, and so sorry to hear about your tomatoes if indeed it is blight affecting them. Hopefully someone in the know will examine your photo soon and can advise.


Sincerely,

(Could be Early Blight, even if it does not look exactly like the
pictures.)

The small spots and yellowing leaves look alot like the septoria leaf spot. It did quite a number on alot of my plants earlier this year when it rained almost every day, but since we've had a dry spell I seem to have been able to stop its spread with generous use of daconil.
