Homeowners apply up to 10 times more pesticide per acre than commercial farmers. Not because their lawns need it — because there's no system telling them how much is enough.

Farmers have agronomists, calibrated equipment, permit requirements, and liability. Homeowners have a bottle and a guess. The result is tens of millions of pounds of excess lawn chemicals applied across the US every year.

Only a fraction of what you spray stays in the root zone. The rest — carried by rain, irrigation, or gravity — runs off into storm drains that empty directly into your local streams, rivers, and lakes.

Phosphorus and nitrogen from lawn products trigger algae blooms that starve waterways of oxygen. Synthetic pesticides disrupt aquatic insects — the base of the food chain for fish, birds, and everything above them. Chemical runoff from lawns and gardens is one of the leading sources of non-point water pollution in the United States.

The label says "2 oz per 1,000 sq ft." You don't know how big your yard is. You don't know how fast your sprayer puts it down. You don't know how many tank loads that means. So you estimate — and estimating almost always means over-applying.

YardMe measures your exact lawn area on a satellite map. It calibrates your equipment — nozzle output, walk speed, sprayer type. Then it gives you a precise number for every tank load.

Not a range. Not an estimate. The right amount for your yard, your sprayer, your walk speed. When you put down exactly what's needed and nothing more, the rest doesn't end up in the river down the road.
