I am renovating 1 acre of lawn, and overseeding a second acre. I know from the other postings that people are using 4 oz per acre rate of Tenacity at the time of seeding. What is the best way to do this? Backpack sprayer or hose end sprayer are my 2 options. For either method, what type of dilution works best? Also, someone had mentioned adding a tracer to their spray. What do you use and how do you use it? It would be a big help knowing exactly which areas have been sprayed and what has not been sprayed. Thanks
