Chuck are you familiar with tobacco mosaic virus?
Any chance you or anyone around your plants smoke cigarettes?
Cages can carry disease year to year.
Is this Early blight (Alternaria solani)? Or Septoria leaf spot (Septoria lycopersici)? Septoria is relatively easy to control, Blight not so much.
There are blight-resistant tomatoes, of which Legend (developed by Oregon State for the purpose) is the most widely available. Mind that no plant is 100% immune however.
Best treatment for blight is a two pronged attack.
First, use plastic mulch sheets. Alternaria spores winter in the ground, but do not attack roots, only leaves and stalks. Insulating the plants from the soil can help a lot.
Second is to treat with copper fungicides on a schedule. I cannot stress the importance of scheduled treatments enough. I usually treat my tomato plants just before transplanting them, then every two weeks. If the weather's rainy, make that every week.
Once plants are at least 3ft high, it may also be a good idea to eliminate the lowest leaves to reduce the chances of contagion even further.
I know I've got Septoria, and probably have early blight as well. I've tried using straw as mulch, thinking that would prevent spores from splashing up on the tomato leaves, but that didn't seem to have much effect. I'll try black plastic mulch this year instead. I'm always behind schedule with tending my tomatoes because I've got too many other chores competing for my attention. Also, because of the blight problem I plant twice as many as I should need in order to get any decent crop at all. But twice as many plants means twice as much maintenance and I start losing interest. This year I'm spacing my plants at around four or five feet apart and planting half as many. Can I be bringing in fungal spores via organic mulches like straw or leaves? Plastic mulch is easy to install, but won't constant walking on it while doing maintenance and harvesting cause it to rip and tear up?
If I'm constantly spraying copper fungicide on the plants won't the copper eventually build up in the soil to toxic concentrations? I've also got Daconil to use up, but I'm not real happy about spraying that stuff on the food I'm ultimately planning to eat. Serenade sounds like a good alternative fungicide, first I've heard about it here.
red plastic is supposed to be good for tomatoes. 3 0r 4 feet wide then leave a walk row between the tomato rows. this is a pic of mulch laid with a plastic layer. it also puts the drip tape down.
View attachment 487673 stakes are then driven in every 3 plants and string ran around the stakes. it's called a florida weave.
Well my guess is (a) The ones on plate (b) look like they were pulled of the store mater vine. and they look more shiny to.
The nursery is coming along nicely: all Kosmonaut Volkov's and Stars of Moscow have sprouted and are growing very nicely. If the weather stays on schedule, like it seems, I'll start hardening them next week and transplant them after the 15th of April. Highly impressed so far by both varieties.
I had to replant part of the Chernyy Slorn, but that was to be expected: "black" tomatoes seem to have low germination and seedlings often die within a few days of sprouting.
As an aside: has anyone ever heard of putting fish offal underneath tomatoes and eggplants as a fertilizer boost?
those certainly are some unique names for tomatoes... quite different from ours... better boy, early girl, solar fire... big boy, etc...
we don't as a rule use fish or parts to fertilize our gardens over here. in the past, yrs ago... the early pioneers did put fish whole out in their gardens and crops to up the soil's nutrients...
a popular fertilizer here is 13-13-13... nitrogen, phosphorus and potassium... %'s....a side dressing of 13-13-13 will 'bump' almost any crop... 07-20-0 better for root crops like spuds...
any pix from Russia? you got any Russian gardening pix? am sure many here would enjoy seeing... I, for one, would like to see some Stars of Moscow...
The tomato plants are still small, and will be put in thefield no sooner than 15 days: it's still too cold outside for them or anything else but early salad, which I've sown last week.
When I moved here a few years ago I found the soil here was very poor. The vegetable patch I built has got about 2" of compost each year, plus two or three NPK fertilizer applications per growing season according to crop. This year I got my hand on a trailer full of manure so I shifted to that.
I am still not fully satisfied with yields, so I am looking for ways to improve them: a common practice here, when planting fruit trees, is to bury 3"-4" of manure underneath the root ball to give the plant a boost during early growth. As tomatoes and other Solenaceae are not big fans of manure, I was thinking of using fish offal for the same purpose.
