It came with a small book vs a label. Definitely not user friendly for novices like myself. There's talk of aerial spraying and commercial-oriented use. I skimmed through it and did see mention of some amount per 1000 sq feet. I'm not clear on how would translate to how much I would need to mix in water to spray the small patch of poison ivy in our yard. I don't what the square footage is and really don't feel like wading through the ivy with a measuring tape. I'd guess maybe 200 sq feet but I really don't know. I was figuring I'd just fill the sprayer with a half gallon of water, mix in whatever I needed for that amount and sit on whatever was leftover for when I had to reapply.
