Safety, storage, and the label

The EPA-registered label is a legal document. Websites, store clerks, and job-sheet estimates do not override it. If this calculator and the bottle disagree, the bottle wins.

PPE, storage, children

• Wear the gloves, eye protection, and clothing the label lists — not a generic assumption.
• Mix outdoors or in a ventilated area. Never mix in food jars or bottles.
• Store locked, in the original bag or bottle, away from children, pets, and food.
• Do not apply immediately before rain when the label says so; runoff is both a water-quality and an efficacy problem.
• State and local rules may ban certain consumer actives (for example, phosphorus fertilizer or specific herbicides). Check before you apply.

If someone is exposed, follow the label’s first-aid section and contact poison control. Do not wait on internet advice.
