In the wine industry, precision and accuracy in vineyard management are crucial to achieving high quality production. However, traditional practices of measuring plant vigor, such as the use of manual or visual methods to assess canopy thickness and height, can lead to subjective and inaccurate results. This approach not only compromises precision in vineyard management, but can also lead to excessive use of pesticides, with negative consequences for the environment and production costs.

To address this challenge, iAgro was developed, an innovative application designed to Objectively and scientifically characterize the vegetative development of each plant. iAgro offers agricultural technicians and winemakers a reliable and efficient alternative to manual measurement, providing optimized data for calibrating sprayers for pesticide distribution. In addition to improving accuracy in the application of phytosanitary treatments, the data collected by iAgro also allows for the following Make informed decisions about the overall management of the vineyard, including fertilization and scheduling of the grape harvest.

Use of the iAgro app in the vineyard.

This case study focuses on a test vineyard at a major Chianti Classico winery.
During the 2023 crop year, a survey was carried out through the use of the iAgro app to
characterize the vigor
of a vineyard of about 5 ha and to
generate a prescription map in two classes for differentiated phytosanitary treatments
(Fig. 1). The test was performed on May 30, 2023, during the phenological flowering stage, sampling 15 plants.

With iAgro, by rapid photographic scanning to all sample plants, it was possible to generate the relative 3D model (digital twin) (Fig. 2) and quickly and objectively measure several parameters, namely:

  • the height, thickness and volume
    of the scanned floor plan;
  • the Leaf Area Index (LAI);
  • the Leaf Wall Area (LWA);
  • the Tree Row Volume (TRV);
  • The optimal dose of water for plant protection treatments.

By sampling a sufficient number of well-distributed plants in the field, the app automatically generated maps of vegetative vigor (LAI index), which were then used to generate a prescription map for variable and optimized phytosanitary treatments based on actual vineyard needs (Fig. 4 and Fig. 5).

Depending on the disease to be combated (e.g., downy mildew) and the farm sprayer, the app is able to suggest the correct dose of water and pesticide to distribute, always respecting the manufacturer’s label.
During the case study, thanks to iAgro it was possible to save 73% water compared to farm doses and better distribute pesticides. This not only represents significant savings in water resources, but also demonstrates a tangible advantage in optimizing pesticide use, Improving product distribution in areas where there is the greatest need.

With iAgro, digital agriculture joins the wine-growing tradition, enabling a
management that is more efficient, sustainable and based on objective data.
The app is intended to be a tool to
promote smart and environmentally friendly agricultural practices
, aiming to
improve the quality and profitability of wine production.

With an innovative tool such as iAgro, you not only achieve improved vineyard management, but also open the door to further developments directly involving the end consumer. For example, through a dedicated company page, it would be possible to show in a transparent and engaging way what happens on the field during each year, thereby improving the company’s image in the eyes of consumers.

Data collected in the field could be used for marketing purposes, providing the consumer with detailed information about the production process, seasonal weather patterns and more, going on to add value to the product, creating a deeper connection between the company and the consumer.
