What is the tank life for Southern Ag Atrazine Weed Killer for St Augustine Grass?

Atrazine 4L


Once an herbicide like Southern AG Atrazine Weed Killer for St. Augustine Grass has been diluted in your spray tank, the solution should be used within 24 hours.  The diluted solution will start to break down and become unstable, lose it's effectiveness, and could potentially cause corrosive effects on your sprayers' components.
