The free plan gives you the 7-day forecast summary and optimal window. The paid plan gives you every tool you need to plan, log, record and stay compliant.
Extended hourly forecasts so you can plan your spray runs with confidence. See exactly which hours are green, which are marginal, and which to avoid — for every day of the week ahead. Wind and rain probability charted hour by hour, plus an hourly wind table.
Record every spray job as you go — product, rate, water volume, paddock, operator, equipment and weather conditions. Every job logged in under a minute, straight from your phone in the paddock.
Photograph your product label and AI reads the batch number and expiry date directly into your job log. No typing, no transcription errors — just point, shoot and spray.
Current wind speed, temperature, humidity and Delta T pulled automatically into every job log at the time of application. Accurate conditions recorded without lifting a finger.
Search 1,480 registered herbicides across Australia, New Zealand, the USA and Great Britain — sourced from each country's official register, with grazing WHP and Safe to Graze dates where the label provides them — added directly to My Products so your logs fill themselves.
Calculate your actual application rate based on boom width, speed and nozzle output. Get it right before you start — not after you've run out of mix three paddocks in.
Mix multiple products in one tank and SprayCast calculates the volume of each product needed for your tank size and target rate. Compatible products, correct volumes, every time.
Look up withholding periods and safe-to-graze dates for any product in the database instantly. Know before you spray when the paddock is safe to return to stock.
Generate spray job reports to send directly to clients, agronomists or auditors — branded, detailed and ready to sign. Export your full spray records as professional PDFs with a tap, straight from your phone. Available on every plan for records you've already made.
SprayCast records capture the date, location, product, rate, operator and the weather at the time of application — the details an auditor, accreditation program or produce buyer asks to see. Export them as PDF or CSV on any plan, for as long as you keep your account. Record-keeping rules differ by state and country, so check what applies where you farm.
Every grazing withholding period in SprayCast either traces back to the registered label or is clearly marked as an estimate or your own entry. Here's exactly what's in the catalogue — and what isn't.
| Country | Products | Register / source | Label-verified | No grazing | Unverified | Estimated |
|---|---|---|---|---|---|---|
| Australia | 385 | APVMA PUBCRIS public register (May 2026) | 343 | 23 | 19 | 0 |
| New Zealand | 205 | MPI ACVM register + product label PDFs | 95 | 1 | 109 | 0 |
| United States | 714 | US EPA register + product label PDFs | 350 | 100 | 264 | 0 |
| Great Britain | 176 | HSE register (product identity only — no label text published) | 0 | 0 | 0 | 176 |
| Total | 1,480 | 788 | 124 | 392 | 176 |
The catalogue is built from each country's public register as at the date of our export. It is not every herbicide sold in your country. If yours isn't there, add it as a custom product — it will be flagged as user-entered wherever it appears.
SprayCast shows you where each value came from:
Where a label is held but carries no usable grazing statement (“unverified” above), SprayCast shows no WHP rather than guessing. The same marker follows the value into the record and the exports.
SprayCast helps you record and calculate. It does not replace reading the current product label, and it does not replace your own compliance obligations. Always check the label before spraying and before returning stock to a paddock.
Labels change. We refresh the catalogue when each register publishes updated data, not on a fixed schedule. The source dates on the Data Sources page tell you how current each country is.
