Spraying is prohibited at a distance ranging from 0 to more than 100m from watercourses and water points, in an area called untreated zone (ZNT). The distance to be respected is defined for each product and can be found on the label on https://ephy.anses.fr/ or in the ACTA index. In the absence of indication, the ZNT is 5 m. Regarding mineral and organic fertilizers, distances depend on the nature of the product, the regulatory regime of the farm, and the location of the plot (vulnerable zone, etc.). Regulatory texts also define spreading prohibition periods. For fertilizers and pesticides, distances can be reduced under certain conditions (presence of hedges, anti-drift nozzles, etc.).
Example of implementation: For an insecticide treatment against tortrix moths on protein peas using Fury (active substance: thiacloprid), the untreated zone is 20 meters.

Regulation
POSITIVE influence
Legal texts making compliance with untreated zones and minimum spreading distances mandatory and defining application modalities.
Order of September 12, 2006 relating to the marketing and use of products referred to in Article L.253-1 of the Rural Code; Article R211-48 of the Environmental Code; Nitrate Directive; Birds Directive (Natura 2000); Prefectoral orders concerning action programs on nitrate vulnerable zones.

3. Effects on the sustainability of the cropping system
"Environmental" criteria
Effect on air quality: Increasing
Phytosanitary emissions: DECREASE
GHG emissions: NEUTRAL
Effect on water quality: Increasing
N.P.: DECREASE
Pesticides: DECREASE
Other: No effect (neutral)
Pollutant transfer to water (N, P, phytosanitary ...): Decrease
Pollutant transfer to air (N, P, phytosanitary ...): no effect (neutral)
Very slight reduction since part of the surface is untreated or unfertilized.
Fossil energy consumption: no effect (neutral)
Very slight saving by reducing the area to be treated or fertilized.
GHG emissions: no effect (neutral)
Biodiversity: Increase
The untreated zone can serve as a refuge for certain animal or plant species. Low-competitive and heritage-interest weeds can be favored in a less nutrient-rich environment.
"Agronomic" criteria
Productivity: No effect (neutral)
Untreated and unfertilized areas are generally small compared to plot areas.
Soil fertility: No effect (neutral)
Water stress: No effect (neutral)
Functional biodiversity: Increasing
The untreated zone can serve as a refuge for certain animal or plant species useful to agricultural production (beneficials, soil fauna, etc.).
"Economic" criteria
Operating costs: No effect (neutral)
Very slight savings on phytosanitary products and/or fertilizers.
Mechanization costs: No effect (neutral)
Very slight savings by reducing the area to be treated or fertilized.
Margin: No effect (neutral)
"Social" criteria
Working time: No effect (neutral)
Very slight savings by reducing the area to be treated or fertilized.
Observation time: No effect (neutral)
