Leaf wetness refers to the presence of free water on the leaf surface and is a key indicator in assessing the risk of fungal diseases. When accurately measured, it provides valuable insights that can enhance the precision and timing of your treatments.
Leaf wetness is calculated by measuring changes in the electric field across the leaf surface. This requires a sensor placed as close as possible to the leaves. The Leafcrop (Sencrop's connected leaf wetness sensor) simulates a natural leaf and transmits data every 10 minutes for ultra-precise monitoring.
The humidity sensor simulates the natural characteristics of the leaf to allow farmers, winegrowers and arborists to obtain precise and reliable measurements from the heart of orchards or vineyards.
It must therefore be placed in the heart of the vegetation so that it undergoes the same humidity and foliage conditions as the plant.
Without a weather sensor to measure leaf wetness, it would be necessary to walk around fields to observe the presence of water on the leaves. However, it is also essential to know how long this water remains on the surface of the leaves, which is not possible through simple monitoring. Connected wetness sensors therefore provide much more precise information that is automatically recorded!
The Leafcrop sensor is now widely adopted by many UK & European winegrowers and arboriculturists to refine the positioning of their treatments.
Leaf wetness conditions play a crucial role in disease development, particularly fungal diseases such as downy mildew and powdery mildew. By closely monitoring leaf wetness, farmers can anticipate disease risks and plan their interventions with confidence.
Humidity also plays a crucial role in determining the optimal timing and positioning of treatments.
By anticipating critical wetting periods (e.g., more than one hour with high humidity), you can plan your treatments at the right time, reduce your IFT (and therefore reduce your expenses) and gain efficiency.
Leaf wetness is also a key piece of precision meteorological data, essential for the effective use of certain Decision Support Tools (DSTs) such as Rimpro or VitiMeteo. Leafcrop, Sencrop’s leaf wetness sensor, provides these DSTs with ultra-local data, enabling highly accurate and personalised agronomic recommendations tailored to your specific field.

Potato late blight is the most feared fungal disease among potato growers. Without proper monitoring and treatment, yield losses can reach 80 to 100% of the harvest. Understanding the disease, knowing how to recognise it and anticipating its onset are now essential to securing your crops. What Is Potato Late
Nitrogen, fertilizers, pesticides: your inputs are expensive. Very expensive. And when heavy rain hits right after application, some of it can literally disappear beneath your feet. Leaching is an often underestimated phenomenon, but one that can have a direct impact on yield, treatment effectiveness… and your wallet. 💡 Good news: there
