The Sonar concentrate is $700 quart. That's what was recommended and what I bought and used. The Sonar RTU (Ready to Use) is much cheaper and diluted. You basically pay for "x" amount of the concentrate either way you go. But, it did work and I'll be using it again in the future if needed.
Tim, as you know, simply referencing "SONAR" can be misleading nowadays since there are multiple formulations.
SONAR A.S. is a 4#a.i./gal formulation of fluridone (active-ingredient ~ a.i.), while SONAR GENESIS is a 1/2# a.i. per gal formulation. Therefore, on a straight a.i. to a.i. comparison, SONAR A.S. is 8X the a.i. concentration of SONAR GENESIS. That being the case, one quart of SONAR A.S. is equal to 2 gal of SONAR GENESIS (on an a.i. basis) but SONAR GENESIS also has some other unique characteristics that go beyond the a.i. concentration - which are very obvious to anyone who has applied/used both formulations.
Do not confuse SONAR GENESIS with SONAR RTU, which is (as you stated) highly diluted and ONLY cost-effective on VERY small ponds - i.e. those that can't justify at least one gal of SONAR GENESIS (which is equal to 1 pt of SONAR AS).
Are we thoroughly confused yet???
