Varieties and foliage diseases - Page 2

I am in the worst battle with septoria I've had. A lot of years my garden is free of non-organic -cides. 2015 is not one of them. Tonight I pulled out the Chlorothalonil and treated my tomatoes as my previous treatments were not proving sufficient.

An update to the topic of this thread.

Sungold and Black Krim, like other years are showing good tolerance and much slower spread. Carbon Copy and Margaret Curtain (both new to me this year) are in the same camp as those two.

Mikado Black is my worst one, it's got a few nice sized tomatoes on it, but disease is spreading rapidly, I've trimmed so many leaves off, the plant may end up need pulling. Pink Berkley Tie Dye and Eva Purple Ball x Big Beef F? are showing lower resistance, but quite as bad as the Mikado Black.

Cherokee Purple is kind of in between, not spreading fast, but not as slow as the group of 4 above.

I'll update later as the season progresses.

I've been spraying with Serenade from the beginning and so far so good. We've had tons of rain, and then cool temps, followed by heat, then rain, etc. a real roller coaster ride. We supposedly are heading into a very hot, high humidity week, so I'll be interested to see how my luck runs. I've used copper once but haven't used it since. I also got lucky because I was checking my leaves and found patches of stink bug eggs under a few leaves, so I used horticultural oil and insecticidal soap as well as End all.
I'm growing Margaret Curtain for the first time and she's pretty robust. KBX is also very healthy. I also remove as much of the bottom leaves even in my containers. I put some promix around the base of my in ground plants to help keep the leaves from coming in contact with soil. I'm hoping I can avoid last year's problems. I had to take down several plants from disease.
I have a question about copper spray. Can it slow growth if the solution is too strong? This wwas my first time using it and I read somewhere that it could. So I'm sticking with serenade for now.

Sharon copper can definitely cause some stunting of leaves but it is usually temporary and usually only if you use a high dose of copper. I always use the minimum recommended dose and have had no problems when it is applied at that rate. Serenade just isn't effective down here. I used several gallons of it one year and it might as well have been just water for all the good it did. Maybe it will work up there where the disease pressure is less severe. Daconil is a good preventative as long as you aren't getting too much rain or too frequent rain.

Serenade is not cutting here either unfortunately.
Bill I have another viewpoint- it is second year in a row disease starts at certain location in my community gardens- mind you, soil is tilled twice, village compost was added AND I rebuild raised beds every year- so changes of the soil being the same are not that great... yet exact same place problems started last year it started this year? Magnetic fields? Am starting to think of biodynamic gardening.
