What is your preferred mix ratio for your preferred herbicide. EXAMPLE: Two weeks ago, I was using 56oz of Speedzone per tankfull (12gal). It worked very well. What I'm wondering is would 50oz have worked? Would 60 have caused damage? For those who've sprayed thousands of gallons through their PG's, what is your cocktail? I bought some Triplet LO for round 2....Anyone have experience with this product? I'm looking to get by with the least amount of herbicide, but still want good results.
