Spot the right window at a glance
Green, orange or red: you know instantly whether you can spray over the next 5 days. All the information is in one place.
You stay in control of the decision
HYGO explains exactly why a window is not recommended (e.g. wind too strong, risk of wash-off). You decide with full knowledge of the facts.
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.
Théophile K., Head of Agronomy at HYGO, explains our algorithms
Your precision agricultural weather
HYGO relies on high-definition forecasts and a network of agricultural weather stations for precision tailored to spraying.
The power of 13 weather models
HYGO doesn't settle for a single source. The app aggregates 13 different models to give you the most reliable forecast possible.
Built-in precision algorithm
HYGO automatically selects the most suitable datasets for your location, so you benefit from a precise grid.
HD radar
So that showers never catch you off guard, you get a high-definition radar to see rain clouds coming.

Secure your tank mixes, even the most complex
Complex tank mixes are a real risk in the field. HYGO goes beyond the technical data sheet: it cross-checks your products' constraints to validate the safety of your spray mixture before filling.
Multi-substance management
Plant protection products, biostimulants, adjuvants... HYGO manages the interactions between multiple active substances to avoid unpleasant surprises.
Tailor-made calculated advice
Our algorithm for calculating agronomic losses takes into account the interactions between active substances, so we can define conditions specific to your tank mix.
Our farmers say it better than we can.
"We've had excellent results with HYGO's weather, which stands out for its reliability. For us, it beats every other weather app on our phones, which is why we took out a HYGO subscription for even greater reliability."
Didier T.
Farmer in Marne, France
"I've been using HYGO for a year. As a farmer, you can't know everything about the best conditions for spraying. I add my product and the app gives me the conditions for the week and the risks associated with the spray."
Quentin P.
Farmer in Lot, France
"I've been using HYGO for two seasons. With my farm under environmental certification, it helps me cut my inputs and plant protection products. It's very useful for spraying: I can pick the best times and lower my dose rates. Before, I was only just meeting the certification requirements, but now I have a better margin."
Guillaume R.
Farmer in Isère, France
"The app saves time. You enter the areas and it gives you the volume straight away. If you have slightly complex spray mixtures, it takes them into account."

You probably have some questions
Weather reliability, product compatibility, free access... Here we answer your most frequent questions to clear up any doubts before you get started.
What types of products are available in the app?
HYGO covers more than 20,000 plant protection products and fertilisers, each with its ideal application conditions.
Why is HYGO's agricultural weather more reliable and accurate than other platforms?
Our weather service aggregates 13 different models, so we can choose the most accurate data for your location. We also offer a resolution of 2.1 km², more detailed than most other free agricultural weather services.
Where does the agronomic knowledge come from?
Since 2019, our agronomists have refined our algorithms through micro-plot trials carried out from the very start, by running the spraying on a farm in northern France, and through regular exchanges with our farmer users. These years of fine-tuning and expertise now give us a robust model that is unmatched on the market.
How do you calculate optimal spraying windows?
Our agronomists have designed an algorithm that models agronomic losses for each active substance and its combinations, because each one has its own characteristics and optimal application conditions.
Is the app free for life or just a trial?
HYGO is free for life, with no ads.
Is the advice independent?
Our mission is to help farmers optimise their use of plant protection products. Working with a manufacturer would compromise this independence, which is central to who we are. We have always been committed to not favouring any product or influencing our analyses.
I already use a weather app, why switch?
A standard weather app tells you “it will rain tomorrow”. HYGO tells you “tomorrow between 6 am and 10 am is the ideal window for your fungicide tank mix on wheat, because wind, humidity and temperature will be optimal for your products”. That's the difference between raw data and real, personalised agronomic advice.
Does HYGO work for my crops?
HYGO works for all arable crops (cereals, oilseed rape, maize, sunflower…) and also adapts to vineyards and orchards. Whatever your crop rotation, spraying windows are calculated based on the products you actually use.
