15% average savings for our customers
Cut your treatment frequency and input costs
Fine-tune your dose rates to protect your margins.
The right dose, at the right time.
HYGO analyses the weather conditions on your fields and calculates the right modulation. You only have one question to ask yourself: do I go?


















Spot the right window at a glance
Each window sums up conditions for the next 5 days: wash-off, drift, temperature, uptake. No table to interpret — the colour says it all.
When conditions are good, the dose goes down.
Every parameter is calculated specifically for your spray mixture. No generic recommendation: a modulation tailored to your products, your fields and your conditions.
Agronomic expertise built into the app
More than 50,000 substances and their combinations have been analysed to give you reliable recommendations tailored to your farm.

Our farmers say it better than we can.
Optimise your dose rates, with no compromise on efficacy
HYGO calculates optimal dose rates based on your crops, your nozzles and your field conditions.
You probably have some questions
Dose reduction, savings, reliability of recommendations... Here we answer your most frequent questions about HYGO Optimiser.
HYGO works on an “efficacy first” basis. We start by making sure you spray at the best moment — when the weather and your tank mix ensure maximum product efficacy. Only under these optimal conditions does HYGO suggest a dose reduction, calculated to deliver the same efficacy as a full dose. Result: better protection, no mistakes, less product, more savings.
This figure comes from 4 years of real data across 2,000 farms. Not a marketing promise, not a research-station trial. It's what our farmers actually see on their plant protection product bills. And since every farm is different, some save more, others a little less — but the average result is there, verified and verifiable.
HYGO is the only tool on the market that optimises dose rates for ALL fungicides, herbicides and growth regulators, on ALL crops. Other solutions (such as xarvio) are limited to a few diseases on a few crops. With HYGO, whatever your tank mix, we optimise it.
Most farmers recoup their subscription within the first 1 to 3 treatments of the season. After that, every optimised treatment is a net saving. On an average farm, that adds up to several thousand euros a year.
Yes, it's plug-and-play. The GPS sensor fits any type of sprayer, new or old, whatever the brand. No ISOBUS needed, no investment in hardware. That's one of HYGO's big advantages over precision spraying solutions that require equipment costing €50,000 or more.
Disease models such as xarvio tell you when to spray based on disease pressure. HYGO steps in at the next stage: once the decision to spray has been made, we help you apply it in the best possible conditions. Our tool combines local weather, the specifics of each active substance in your tank mix and the characteristics of your farm to suggest a tailored dose modulation. Result: maximum efficacy with less product. The two approaches are complementary — xarvio decides “when to spray”, HYGO optimises “how to spray”.
Spot spraying is impressive technology, but it's an investment of €50,000 to €150,000, mainly for herbicides and weed control. HYGO optimises your dose rates across all your treatments — fungicides, herbicides, growth regulators — with no hardware to buy. The two approaches are complementary, but HYGO is available straight away to any farm with a sprayer.
No. You set up your tank mixes in the app (it takes a few minutes), and HYGO does the rest: cross-checking with the weather, calculating optimal windows, suggesting dose modulation. No Excel spreadsheets, no field-by-field data entry. It's designed for the field, not the office.
Our algorithms are developed by specialist agronomists and have been tested for 4 years in real-world conditions. We don't deal in theory: every recommendation is validated by field data. And our “efficacy first” approach means we never suggest a reduction that would compromise your crop protection. We'd rather suggest nothing than take a risk.
It's a fair question. The answer: no, quite the opposite. A full dose applied in poor conditions (too much wind, unsuitable humidity, immediate wash-off) is often less effective than a reduced dose applied at the perfect moment. By spraying in the right window with the right dose, you maintain effective selection pressure on pathogens. What counts is the quality of the application, not just the quantity.
From 30 ha to 2,000 ha, everyone benefits. The maths is simple: the more you spray, the more you save. But even on a small farm, the subscription quickly pays for itself. All you need is a sprayer and plant protection products.
Your agronomist knows the products and your situation, and that's valuable. But they can't be with you at 6 am when the spraying window opens, or cross-check 2 km-resolution weather in real time with the specifics of every product in your tank mix. HYGO is the perfect complement: it backs up and refines the advice you already get, and gives you confidence when you climb into the sprayer.
