Every spray, on every block, written down right the first time.

Built by an apple grower in Vermont for commercial fruit growers. Muddy boots, spotty cell service and all.

One season

It already knows what you do in May

Most farm software is a database with a login. This was written by somebody who sprays his own blocks, so it's shaped like the season rather than like a spreadsheet.

Dormant · March

Build the program once

You already know most of the season before it starts. Writing it out twice is the waste.

Tank-mix programs, entered once, scheduled by block for the whole year.

Green tip · April

Copper goes on, the clock starts

The first application of the year is also the first REI you have to keep track of.

Live REI and PHI countdowns on every block, on the map, from the moment you log it.

Tight cluster · April

Scab starts running

Ascospore maturity and infection periods decide your fungicide timing, not the calendar.

NEWA's apple scab model, run against the weather station you choose, flags infection events on your dashboard.

Pink · late April

Traps go up

Catch counts, lure ages, threshold calls — usually on a clipboard that lives in the truck.

Trap network and scouting logged by block, with catches trending season over season.

Bloom · May

Nothing goes on that shouldn't

The window where what you don't spray matters as much as what you do.

Growth stage recorded with every application, so the record shows what bloom actually looked like.

Petal fall · May

The mix that has to be right

Four products in the tank, a rate per acre, and a seasonal cap you're trying to remember.

Label-aware mix calculator with FRAC and IRAC groups and seasonal limit warnings before you spray.

Covers · June–August

The crew logs it, not you

Somebody sprayed the north end on Tuesday. Probably. You'll write it up Sunday night.

Jobs assigned to applicators, logged from their own phones, straight into the record — with a mix sheet built for the sprayer that is actually going out.

Harvest · September

PHI on every block

Pickers are going in tomorrow and you need to know which blocks are clear.

PHI countdowns per block, and a WPS-ready PDF an inspector can read.

The actual app

Not mockups

Screenshots from a working orchard's account. Tap the demo above and you can click around the same thing.

Satellite view of an orchard with active REI countdowns on restricted blocks

Which blocks are closed, right now

Whole orchard on satellite, REI and PHI counting down on every restricted block.

Per-row drilldown showing variety and spray history

Down to the row

Tap a row for its variety, acres, and every application it has ever had.

Product applications with FRAC groups and seasonal limit progress bars

Under the cap, before you spray

FRAC groups and seasonal limits tracked per product, warned about in advance.

Straight answers

What growers actually ask

Will it work on my place?

Alternate middles, partial blocks, mixed varieties in one block — the awkward cases are the ones it was built around, because they're the ones on my farm.

Is my data mine?

Yes, and you can take it with you. Export your records any time, in a format you can open. We don't sell it and we don't hold it hostage.

These are your legal compliance records. A tool you can't leave isn't a tool, it's a trap.

What if you stop?

Fair question to ask a one-person company, and most software companies dodge it. The database is backed up nightly off-site, and export is built in, not promised.

I grow apples in Putney and use this every day on my own blocks. It stops when I stop growing fruit.

Pomona Systems

Three tools for the same farm

Same grower, same problems, built one at a time. PYO Maps reads your blocks and rows straight out of Pomona, so a farm already mapped here is most of the way to a customer-facing map. Sentinel is its own thing — it watches storage rooms and doesn't touch your spray records.

Pomona

Spray records, block and row mapping, IPM scouting and WPS compliance.

Available now

PYO Maps

Your farm on your customer's phone. Blocks and rows straight from your records, what's ripe today, walking directions to the row.

Sentinel MP

Controlled-atmosphere room monitoring. O₂, CO₂, temperature and humidity, with alarms that reach you before the fruit knows.

In development

Try it on your own blocks before you decide.

The demo is a real orchard's data and needs no signup. If it doesn't fit how you work, you'll know in ten minutes and it cost you nothing.
