“The farmer is very hardy. You must adapt or you will dieSerge Bergo says immediately. This motto of the Secretary General of the Departmental Federation of Farmers’ Unions of the Gironde (FDSEA 33), the engineers exhibiting at the Vinitech-Sifel show understood this well. The global event brings together industry players at the Parc des Expositions in Bordeaux from November 25 to 1.eh December 2022.
Among the presented inventions is the Ventigel device. Created by Pierre Perrinet from Bordeaux to combat the drop in temperature, the device protects an area of two to three hectares thanks to its ventilation system. He is the bronze winner of the 2022 Cups. The director of Polypoles, originally an expert in the field of heating, embarked on this Gironde adventure in 2021 together with Philippe Ferrier, owner of the Château Duplessis operation. “ He had that problem, I had some ideas in mindSays the Arts et Métiers graduate engineer, 56 years old. Winning bet. In 2021, despite the black frosts of April 7 and 8, 90% of the grape grower’s production was saved.

An effective Bordeaux invention
“ This system already existedPierre Gaillard, Co-Chairman of the Scientific and Technical Committee of Vinitech-Sifel, which awarded the prizes, analyzes. but what is relevant about the Ventigel tool is its simplicity of use and easy connection“. Marketed for between €26,000 and €29,000 depending on the model chosen, one hundred examples of the car were sold since it was produced in Haillan (Gironde). It runs on less than eleven liters of fuel oil and eleven kilowatts per hour. Its inventor hopes to sell twice as much by 2022, expanding its target to arborists and market gardeners.
Two sections where there is a need. After the spring frost of 2022, the Regional Agricultural Chamber of Nouvelle Aquitaine found a crop loss of up to 80% in some Ente plum farms. Carrots, golden apples and strawberries were also affected. In the area, “each has its own techniqueto combat frostbite, according to Pierre Gaillard. In winter, carrots are planted at a depth of 40 centimeters from the ground, so that they are less affected by the vagaries of the weather. Kiwi growers fight against spraying. The technique involves creating an igloo shape around the buds, keeping them at zero degrees. Effective method, but limited by high water consumption.
Fruit and vegetable growers are in for a treat
Like compensation after a climate incident, these solutions sometimes look like “bandage on a wooden leg– explains Pierre Gaillard, President of Invenio. He believes there are still two main avenues of research on this topic: the genetics of planted varieties and agrivoltaism, which allows you to insulate a field by covering it with solar panels (if you also accept the loss of light).
At the time of his retirement, this association expert in research and development has high hopes.the concept» Vititunnel. The cultivation technique that received a special award from the jury of the “Vinitech-Sifel” show is:disruptive innovation“According to him. Although this system of unfinished tarps sometimes protects crops. A frequency that allows you not tochange the ecosystem“.
