I remember one time this person said what they bought was useless and come to find out he had bought something with only 12.5% Daconil and that would be useless.

Okay, that explains a few things. After reading this, I immediately got up and went and checked my bottle. Sure enough, it's only 12.5%.

No, it's not real Daconil. As a matter of fact, I don't even remember the brand name, but the active ingredient is 12.5 % chlorothalinol. I followed the instructions exactly, which call for it to be mixed at a rate of 1 tablespoon per gallon. I apply it with a 2 gallon hand sprayer.

So are you guys mixing 29% chlorothalinol at 1 Tablespoon per gallon? If that's the case, no wonder I had so many problems with Early Blight. It sounds like I've been using a watered down Daconil wannabe.

How long does chlorothalinol keep in the concentrated form? If I mixed the 12.5% at 2.5 tablespoons per gallon instead of 1, would that be the right concentration?
