What is the mix rate for Tenacity in a 2 gallon sprayer to control poa annua? Treating 7,000 sq ft. One application of Tenacity was done on 8/29 and then overseeded on 9/23.
I applied a broadcast application of tenacity on 8/29 in TN. I have approximately 7000 square feet. I put out the spot treatment formula instead of broadcast formula so I don't think I put out enough. I overseeded on 9/23. I have a 2 gallon sprayer. How much tenacity do I put into the sprayer with 2 gallons of water? Math is hard:). My goal is to control poa annua. I plan on putting out dimension as well in a few weeks.
Answer:
Tenacity Herbicide can be applied at the same time as seeding (unless grass is more than 20% stand of fine fescue). If application cannot be done within 7 days of seeding you would need to wait a minimum of 30 days, or until the seed has emerged and been mowed at least twice before applying to the lawn. Â
According to the Tenacity product label, you will need to mix 1 tsp of product + 3 tsp surfactant with 2 gallons of water for spot treatments applied at a rate of 1 gallon per 1,000 sq ft. It is advised to use a dye like Turf Mark Blue with it so you can make sure to not overlap if you plan to do a broadcast application on the property. Repeat applications can be done after two to three weeks for continued post emergent weed control.
