Spray the patch, not the field.
Weed Mapping turns a drone or aircraft pass over your field into a patch map, so the boom opens over the weeds and shuts off over clean ground. We're running it with pilot partners now.
Blanket rate, because nobody has seen the field
Monday morning the route sheet has fourteen fields on it. Some came from the agronomist's scouting notes, some from a grower who called on Friday, and a few are just fields you sprayed at this time last year. A scout has walked the edges of maybe three of them. For the rest you are going on a phone call and a photo of a fence line.
So the crew sprays blanket rate, boom open end to end. Post-emergence product works on weeds of a certain size, and the fast ones outgrow it in days, so you cannot wait for a better picture. You book the field, fill the tank, drive out. On the field with two weedy corners and a clean middle, the sprayer still covers every acre. The product and the hours go into ground that had nothing on it, and the grower who paid for a full-field pass never finds out.
Guessing the other way costs more. Someone trusts last year's map, the crew skips a patch that came up this season, and the callback lands in the middle of the week's next twelve fields.
A patch map does not change the crew, the rig or the route sheet. It changes what you know about a field before the truck leaves the yard: where the weeds are, so the controller can shut sections off everywhere else.
What comes back
Per pass, per field. On a pilot, that covers the fields you put on the pilot list.
Patch mapPolygons per field
The weed locations for one field, drawn from a single RGB pass and separated from the crop at leaf scale. Every map carries the date and pass that produced it, so you know how fresh it is when you load it.
Spray fileTreat map for your controller
A boom-section-ready version of the patch map for compatible rate controllers. Which controllers and which file format are confirmed for each rig before a pilot starts, not assumed.
Pass summaryChanges since the last pass
For any field flown before, what changed since the previous spray window: patches that grew, patches that are new, and ground that came up clean.
How it works
Fields in
Send the fields on this week's route, as boundaries or a shapefile, and tell us the rig and controller each will be sprayed with.
Imagery
An RGB pass by drone or crewed aircraft, timed to your spray window, flown at 2 cm or finer.
Analysis
Weed is separated from crop plant by plant, then the weedy ground is drawn as polygons.
Delivery
The patch map and the spray file for each field, matched to the pass that flew it. On a controller confirmed for the rig, your crew loads the file in the cab the way it loads any other treat map.
On the route sheet
Use the patch maps when you build the day's sheet. A field with two small patches is a different job from one that is weedy end to end, and you can tell the crew which is which before they leave. Fields with bad maps, or none, go the old way: blanket rate, as today.
The operator still decides whether to run the file. The map informs the rig; it does not drive it.
Limits
The notes beside the sections above, gathered in one place.
Resolution floor
At 2 cm a pixel is about the width of a thumbnail. Seedlings smaller than a few pixels across are not mapped, and weeds that look like the crop from above can be missed or merged with it.
Your rig sets how fine it gets
A boom shuts off by section. A patch narrower than one section is still sprayed at section width, so the file cannot be finer than your boom.
Controller support is per rig
The spray file works with compatible controllers, confirmed case by case. It is not universal yet.
Daylight and clear conditions
RGB needs daylight and reasonably clear skies. Heavy cloud, low sun or dusk passes get rescheduled, which can push a map past your window.
No savings figure
We publish no chemical-savings number. What a field saves depends on how weedy it is and how your controller handles sections.
A pilot, not a product
This runs with pilot partners while coverage and controller support grow. Expect a scoped pilot, not a subscription you sign up for online.
Who it's for
For
- Operations leads and dispatchers at custom applicators building a weekly route sheet
- Agronomy center managers who run their own application crews
- Outfits with section-control sprayers that already load treat maps
Not for
- Growers looking for a drone to fly their own fields
- Anyone wanting a guaranteed chemical saving before a pilot
- Sprayers with no section control or map-loading terminal
- A spray decision made without an operator looking at it
Questions before a pilot
Is this available everywhere yet?
No. We're running it with pilot partners while we scale coverage and controller support. Tell us where your fields are and we'll say whether we can fly them.
Which controllers does the spray file work with?
That is confirmed rig by rig, not assumed. Tell us the make and model of the controller and terminal in your cab and we'll say whether the file will load.
Does it guarantee chemical savings?
No. We publish no percentage. Savings depend on the field's weed pressure and how your rig's section control behaves.
Does it work in any light?
No. RGB needs daylight and reasonably clear conditions, so a cloudy or dusk pass gets rescheduled.
How do we check it against what we see in the field?
Pick a few fields your scout has already walked and compare the patch map with the scout's notes before you load any file. Decide whether it is good enough to plan with.
Who does the flying?
We arrange the drone or aircraft pass for the fields on your pilot list. Tell us about any airspace or customer restrictions up front.
How fresh is a map?
Each map belongs to the pass that flew it. A weed patch that came up after the flight is not on it, so time the pass close to the spray window.
Who owns the maps and the imagery?
Ownership and licence terms are written into the pilot agreement before any flight is ordered. If a grower's contract limits what you can share, raise it early.
How is a pilot bought and priced?
The quote depends on the fields and how you want the passes flown, and it is set for your pilot list. We do not publish a price.
Put the map on the route sheet.
Tell us which fields you'd fly, what rig sprays them and when your spray window opens. We'll tell you plainly whether we can meet it.
