Allen from Columbia, Sc writes

What is the shelf life of Southern Ag Atrazine Weed Killer for St Augustine Grass after it's been opened and stored in an insulated garage?

Would a surfactant be recommended to add to the tank mix if it's been stored for year?

Answer:

Southern Ag Atrazine Weed Killer for St Augustine Grass should have a shelf life of between 3 to 5 years, if it is stored in a temperature stable environment, away from direct sunlight.  A non ionic surfactant is not recommended to be used with this product.
