Is this bacterial speck or spot?
I have some tumbling toms hanging from the side of the house and they had an enourmous amount of water pour into them from the roof from a big rainstorm two weeks ago. It clearly stressed them. I have attached some pics, do you think this may just be symtoms of a stressed plant or do they have a disease like bacterial spec or spot?
Thanks, Qweniden |

Q,
I am seeing EXACTLY the same thing on several of my plants as well, here in Campbell. So is a friend in Livermore. I chalk it up to more than double the amount of rain in March and April here this year. Good news is that all of the new growth over the past 2 weeks is blemish-free. Raybo |

For me, all my plants are fine (like 40 of them) except these tumbling toms that had the roof water pour on them. I hope I dont have to toss them!

Q,
I have a row of 'Tainers adjacent to the house, and our hard rains overflowed the gutters for a while and drenched them for quite some time. Sounds just like what happened to your one plant. The good news is that the new leaves and branches look fine, where some of the older stems are brown, like in your pictures. I am hopeful that now with temps in the 80s and no rain for the rest of the Season (as typically happens here), we will be in good shape. Raybo |

The large black spots on the leaves, some surrounded by yellow areas are quite typical of Bacterial Spot, which is spread by air and in rain droplets.
And since a couple of you have said that new foliage looks OK if it were me i'd take off and dispose of all foliage with those symptoms and dispose of them ASAP so there's no possibility of spread by bacteria falling to the soil and reinfecting by splashback either by rain or irrigation. The black edges on some of the leaves do look like the result of water logging, so possibly two things going on at the same time.
