It is neither early blight nor late blight. Right now I would say that they have a bit of septoria. If I look closely at one or two of those photos, there are some signs of it. Also, there could be an issue with either over-watering or soggy soil that's not draining well. Of course, we can't do a lot about all this rain, *sigh*. For the septoria, which doesn't look horrible right now, I would use a fungicide for vegetables - one that contains Chlorothalonil (Daconil, Ortho Garden). Use according to package directions. All fungicides must be used as preventatives; none are curative. They will not kill existing disease but will keep it from starting and spreading. And, they must be applied regularly. If you are gardening organically, I would go with one of the copper-based fungicides. Follow package directions for dilutions and frequency of application. Now I'll let you in on a little secret here in the Northeast: :-) Septoria is usually transient. Once the weather dries out and the temps increase, it will stop progressing. It is the cool, wet weather that creates the environment for it to thrive. So, you don't normally get a fungicide just for septoria. However, a fungicide will help prevent early blight, which is very common and far more difficult to arrest. And, if there happens to be any late blight around, it will help to prevent that as well. So it's worth using to prevent other fungal diseases. You can remove the affected leaves, but don't feel that you have to remove every leaf that has a small spot or two. As the septoria stops, it will just leave a few spots on an otherwise perfectly good leaf. However, if you're looking at cool temps and rain for another week, you may want to be more aggressive about removing affected leaves. Some folks say that you should bag the affected foliage and throw it in the garbage to prevent the spread of disease. Do that, but don't think it will forever eliminate septoria and early blight. Those fungi are all over -- in the air, in rain droplets -- so you can be extremely fastidious and still get those fungus diseases. Just an FYI. Happy gardening!

What's the soil situation like -- soil type, any amendments? Have you fed them at all? I'm thinking that's an odd pattern of yellowing you've got there... it almost never starts from the base of the leaf like that. Whitefly can cause some yellowing on older leaves and saps vigor, but you didn't mention how well the control is working. If you haven't fed them, the first thing I'd try is a balanced fertilizer. That uniform yellow color isn't early blight (EB has dark spots); Verticillium tends to make the entire plant sag during the day as if it had gone dry, and can affect some branches more than others. I wouldn't rule out V. wilt yet, but try the fertilizer first, and check the levels of whitefly on the plants. --Alison who has had some of the same problems in the past, with weak soil... until the mites would come in and demolish the stunted little plants. Too much nitrogen is bad, but it is possible to have too little as well.

I have 3 tomato plant one beside each other in raised beds and the first one got early blight (many lower leaves infected and some tomatoes have light brown spot on them) but the others seem fine so far so I was wondering if it was logical to pull it out to prevent other tomatoes of catching it too? I have another 10 plants too but in different raised bed next to them. What i read to do to is to remove the lower leaves of my plants, to remove infected leaves and to spray an anti fungal spray (I heard water and baking soda works) does that seem right? If i don't pull out the whole plant should i remove affected tomato fruits as well?

I've been feeding them with compost tea when I water twice each day. Like most tap water, mine has a a fairly high pH, so minerals may not be as available to the plants as they should be. I try to avoid all toxic stuff, but I do use non-organic fertilizers when my compost for tea is either used up or washed out. I mainly compost maple tree leaves and grass clippings that I bag with the mower each fall. I gave the plants dose of Epson salts and bought a small package of Miracid fertilizer with trace elements. I'm going to try adding a small bit of this each day with their water to lower the pH and supplement their feed now that I am running out of compost that is not already washed out. The rate of leaves dying has slowed down a bit, so it looks like the plant might survive to give me a fall crop after the weather cools down a bit. I am not sure if the improvement is because our temp for the past week has finally dropped from over 100 to the high 80s. It may also be that the sick leaves are the left over ones from before I got rid of the last few aphids and mites. I cannot find a single aphid or mite anymore. It cannot tell for sure which growth on the plant as emerged since the final bugs were beaten. I did take some of the leaves and hold them up to a flash light last night to see if there were any pin-holes. The leaves that have any yellow all seem to have some tiny holes that light would shine through, but the newer mature leaves do not have any holes or yellow. Thank you for the suggestion regarding the magnesium. Between the Epson Salts, more balanced pH, lower temp, and beneficial bugs, I hope somethings works. If I can get this problem with leave drop fixed, I think I can get a good fall crop. The plant's basic stems and roots seem to still be very healthy and there is enough new growth with leaves to still produce a good crop once our night temps drop back below 70 so my blooms will set fruit. Knoxville is near the mountains, but down in river valley, so our cool fall temps are moderated. Last year, I was able to cover my plants with a sheet at night for the first 3 or 4 frosts, and then we got a warm spell without more frost until mid November. After I gave up and picked the green fruit before our first really cold night, I had ripe tomatoes until nearly Christmas. Between tress and my 4 dogs which love to dig, I had a hard time finding a good place to grow a couple of tomato plants, so I've grown 2 or 3 in pots for the past few years. I read about the Topsy-Turvey tomato planters that a local man had invented, so I decided to try the idea 2 years ago. For anyone that wants to grow tomatoes next year in a container, I recommend the idea highly. I don't have to stake them and the plants are clean and dry up off the ground. I'm disabled and living on social security, so I try to make do with things I can scavenge whenever possible. For my planters, I use a 5 or 10 gallon bucket. I tied a strong nylon rope around the top of the buckets, because I did not trust the handles to be strong enough to support both the bucket's contents and the plant's growth. I drilled a 2 inch hole in the center of the bottom of the buckets. When I transplant my seedlings, I sit the bucket right-side-up on the edge of a table with part hanging over the edge so I can get to the hole in the bottom. I slide the plant's roots up from the bottom through the hole in the bucket and then wedged soft sponge-like foam around the plant's stem to keep it from falling out and keep the dirt from running out when I add it next. After the tomato plant is in the hole with its foam collar, I reach in the top of the bucket and pull the plant's roots and stem up into the bucket until only the top stems and leaves of the plant are hanging out of the bottom of the bucket. I then add enough dirt to hold the plant in position. Pause before adding so much dirt that the bucket gets too heavy to lift up to hang. Warning, this thing will get heavy, so a simple cup hook screwed into the overhang will not be enough to hold it once you get it full of dirt, watered, with several feet of foliage. While it is somewhat clumsy to put together, if you have a place to hang it that gets lots of sun, it works great. I was lucky in that someone in the past had already put up a mounting for a swing on the porch. The porch is so sunny, it lends itself better for container gardening than it does for a porch swing, so I use the heavy hooks intended for a porch swing with two adults, to instead support large hanging tomato plants. After I have the pots hanging, I then finish filling the buckets with a mixture of compost and potting mix. I use fresh potting mix each year and wash the buckets with bleach each spring to avoid soil borne diseases and pests from the prior year. In full sun and heat, I water the plants each morning and afternoon. As the stems grow, they will tend to curve back upward in graceful "swooping" arcs that almost hide the bucket they are growing in. Once the plants are heavy with full-sized fruit they will hang more straight, so try to put the pot as high as you can, and still be able to reach up to water it from the top. Cherry tomatoes plants make a very beautiful hanging plant when grown this way. The graceful arcs of lush green leaves are accented so well by the clusters of ripe fruit, you would be tempted to leave then on the plant for decoration, if they weren't so tasty. They are so good, that many of them never even make it inside the house, because I cannot resist picking a few to eat fresh from the vine, every time I go outside and walk past them. While they don't produce bragging sized fruit, I always plant a cherry tomato plant because they are so predictably productive. For me, they always seem to be the most disease and pest resistant and best at continuing to set fruit during the hot summer. Greg
