How to conciliate application of plant protection products and protection of bystanders - CAPRIV: a French collaborative project

Résumé

People living nearby agricultural crops may be exposed to plant protection products emitted from the sprayed fields. Risk management measures include safety distances that establish a minimal distance between the sprayed zone and the limit of the agricultural plot adjacent to an inhabited place or frequented by bystanders. These references have been considered in the new French regulation of 27 December 2019 on measures to protect people when using plant protection products. In the absence of a specific safety distance set in the label, a minimum untreated distance of 20 m is now required for the most toxic products. For other products, the safety distance has been set at 10 m for orchards and vineyards and 5 m in field crops. The French project CAPRIV aims at better determining the effect of drift reducing technologies (DRT) on the exposure of residents (bystanders). Spray drift occurs at the time of the application and mainly depends on the droplet size distribution (liquid phase), the typology of the spray application techniques and the atmospheric conditions. Post-application volatilization (gaseous phase) depends essentially on the characteristics of the product (volatility) and atmospheric conditions. The first step of the project focused on spray drift and consisted in developing and evaluating a harmonized methodology for assessing simultaneously sedimentation drift, airborne drift and resident's exposure. This methodology is implemented during the 2021 season on field crops, orchards and in controlled conditions on an artificial vineyard.
