Organic tomato problems on leaves, Help!!

posted by: TOTEMs on 06.18.2013 at 10:05 am in Organic Gardening Forum

So I have a little over a hundred tomato plants that are not doing well. They are a mix of marziano, black cherry, brandywine, and black krim. Most are started from saved seeds.
I live in northern CT and we have had about 2 weeks straight of rain.

Also I got late blight last year in the same spot really late in the season. I pulled all plants and bagged them to the dump.

also I should add that it seems that the lower leaves are the most affected. The plants seem to have a very very slight droop to them.
When I had blight before it seem to show up more in the steams first then effect the leaves. Maybe a pest?

I use no spray of any kind.

It is still early in our season if I need to pull them and start over with local greenhouse starts. Thoughts?

Here is the response I got from my local extension:

Your tomatoes (and most tomatoes on farms) have septoria leaf spot, a fungal disease that is a little more aggressive than early blight. Most fungal and bacterial diseases start on the lower leaves and work their way up the plant.

If you have the option to pull a few plants with this disease and plant some from a local greenhouse, that may protect the rest of the planting. If the spots are on too many plants to pull them all, then you can at least slow it down by removing lower leaves. Without a commercial fungicide, it may still spread.

This goes with the picture I've also clipped.

Vinegar is very effective if temperatures are above 70 degrees F. and if you mix in, per gallon of regular or cider vinegar, 1 tablespoon per gallon of Ivory dish detergent and 2 tablespoons per gallon of canola oil. Repeat spray when leaves started to green up again, which depends on temperature and moisture. I studied and honed the vinegar method after writing my book 'Weedless Gardening' (Workman Publishing, 2001), and now buy vinegar in bulk.

Great idea!

RE: Converting lawn to veggies; bermuda grass question (Follow-Up #1)

Sheet mulching is my favourite way to suppress grass and weeds and start a new bed. My approach is: first, a layer of cardboard, overlapping such that there is nowhere for grass to penetrate; next a layer of well-rotted manure; then a layer of straw--NOT HAY, (you'd be amazed how many people mistakenly use hay, as opposed to straw!); finally a layer of good topsoil, or my favourite, SeaSoil. You can then plant directly into this top layer. Not only do you avoid all the work of tilling, but you promote a much healthier soil ecology, and subsequently better plants. Be careful of your topsoil sources--I have seen a lot of properties unwittingly import horsetail, morning glory, and other nasty beasts by purchasing cheap material. That will leave you longing for bermuda grass! There is a lot of info on the web about sheet mulching, or 'lasagne gardening', as it sometimes called.

A soil test is always a good idea. It will inform you of any deficient or toxic mineral levels, and if you need to adjust your soil pH. Personally, I think you will never make a better investment in your garden.

I would mention that using pressure treated lumber for a vegetable garden is not advisable. I would replace it with rough cedar, which is relatively cheap, and will last years.

NOTES:

An idea of how to cover over grass without tilling or removing.
