What is the best spray to use on a weekly basis to prevent late blight?

I'd like to stay organic, but results I've seen don't look too promising in that category.

organic won't help you here, blight can be very strong,
in the begin it could work but later on the plant will eventually have some dammage.
the only thing you can do is prevent it from getting it.
air circulation for example or give you plant an aditional shot of calcium. it's mostly based on strong celles in the
tomato vine , strong celles won't get infected fast so in my opinion this is the only bio way to get or to prevent late blight. ( just my thoughts about this subject)

Chlorithinol (daconil) is the only preventative spray listed for late blight by the information on the web for it.

It's worth a try. I use it, and my plants are healthy and productive.

Thanks everyone for your input, especially Wilbur, my bro from VGVGA here in VT.

Copper compounds, it appears, are very toxic to everything, and should be used as the nuclear option.

So chlorothalonil it is, following all precautions before consumption.

Mancozeb works very well also and is lesss toxic than clorothalinol products. I used it last year and had no problems while my next door neighbors plants all died.
