When it was first introduced as Roundup it was $100. I remember. The $10 glyphos I bought yesterday is the same brand $30 glyphos I was using last year and I didn't have any trouble with it then. It's called glyfos x-tra or something like that. The x-tra is surfactant. Chinese glyphos. Made in Mexico for a company in Denmark. It's the new world order, man. Do you mean your generic separated after you mixed it? What brand name was that?
