One thing to remember when reading a label. Whether its prop blend or clearly labeled, first ingredient always contains the most. Its labeled most to least. So by the time you get down to the final few ingredients, they're usually just a sprinkled amount that wont do anything for you. Alot of people really enjoy the activate and triazole. See it all over in pcts around the world, so its probably safe to say they're a legitimate bet in the case of prop blends, because it works.
