Tenacity/Mesotrione variations

Those products are not labeled for grass of any kind, commercial or residential. Remember, the label is the law.

They are not the same product either. They have the same technical ingredient (mesotrione) but are formulated differently to be most effective for their specific application (ag vs. turf). A quick look of the label shows Tenacity has a label limit of 16 fl oz/A per year whereas Explorer has a label limit of 7.7 fl oz/A per year. Much of this has to do with the crop and fate in the soil.

One easy way to tell they are not the same product: look at the EPA registration number on the title page of any pesticide. If the numbers are the same, it's the exact same product. Syngenta, for example, makes a PGR called Primo MAXX with an EPA Reg. No. of 100-937. Syngenta also makes a private label PGR called Podium with an EPA Reg No. of 100-937. Same exact product. Easy way to tell if there is a difference when comparing products.
 
but I’ll tell you this from extensive first hand knowledge the performance is the same between the two products. Don’t use the +\- 1 fl oz per gallon of methylated seed oil for rather more like a 1/3 fl oz but that right there will get you more bang for your buck and broadleafs especially clover are bad do yourself a favor and tank mix in some millennium at half rates or about .75 fl of per gallon(or some formulation of 2-4d or dicamba. Do you have mature crabgrass? Then grab yourself some drive (aka quinclorac) use it at reduced rates. I’m not as familiar on that tank mix partner yet. One last tip on how to get ya further with less tenacity but it starts getting riskier in terms of getting it to hot but grab yourself some straight urea and rates for that is 8 lbs of urea into 100 gallons of water
Millenium isn't labeled for residential. So that's two strikes. Choke up and protect the plate, Champ.
