Does a long storage time reduce the efficiency of Tenacity?

Tenacity worked wonderfully on my lawn when I first got it but I have stored it for approx. 3 years and the stored product does not seem to be working at all to kill weeds. I stirred it thoroughly before adding to water in sprayer. I used the recommended 1/2 tsp. per gal. of water.


Tenacity Herbicide if stored in a cool dry area will last up to 3 years. It sounds like you need to purchase fresh product. The mix rate you are using is correct.
