ECOPHYTO area: alternative spraying systems
The goal of the national ECOPHYTO action plan is to significantly reduce the use of crop protection products to lessen the associated risks. The use of crop protection products causes many local conflicts which are attracting growing media attention. In wine production, it is clear that the existing range of sprayers and most new equipment are out of step with agro-environmental and societal challenges (to reduce the use of crop protection chemicals, lessen environmental risks and reduce exposure for equipemnt operators and local residents).
This raises a number of questions :
How to choose a high-quality sprayer ? How to treat less but more efficiently ? What is best practice to prevent spray drift ? What nozzles to use, and what pressure ? Why invest in collection panels ?
The Direction Régionale de l’Alimentation, de l’Agriculture et de la Forêt d’Aquitaine (DRAAF), in partnership with the Institut Français de la Vigne et du Vin (IFV), IRSTEA, INVENIO and Chambre Régionale d’Aquitaine look forward to meeting you in the ECOPHYTO area to answer these questions.
The programme will include an exhibition of equipment, talks and discussions with technicians, equipment manufacturers and distributors.

Vineyard sprayers vary widely in terms of technology as well as in machine configuration. Without agronomic and environmental performance indicators, it is difficult for industry professionals to identify the highest-performing equipment and to recommend spraying practices that reduce the use of crop protection chemicals.
The research carried as part of the EcoTechViti Joint Technology Units (IFV, IRSTEA, Montpellier SupAgro/IHEV) on the question of optimising the use of the crop protection chemicals has resulted in the development of a new tool to measure agronomic and environmental sprayer performance: EvaSprayViti. This tool is a flexible artificial vine which allows objective and repeatable measurement of spraying quality and tests the performance of different spraying equipment and practices. It reproduces 4 rows of vines at 3 different stages: early, middle and full growth.
IFV and IRSTEA, working closely with the French Food Directorate DGAL have signed an agreement with the National Office for Water and Aquatic Environments (ONEMA) whose aim is to evaluate the agro-environmental performance of around 30 machines representing the wide range of sprayers and to suggest specifications for setting up routine tests to classify equipment based on its ability to reduce the use of crop protection chemicals.
