The Decree of 4th May 2017 and according to Article L. 253-1 of the Rural Code allows for the reduction of non treated zones of 50 or 20 m to 5 m, provided the following conditions are fulfilled:
- A vegetated strip of a width of more than 5 m along the water body is established (full or dotted blue lines on IGN maps 1/25000 or department map of the concerned water bodies
-The use of drift reducing material reducing drift by a factor of 3 for aquatic environments (official list of accredited “ZNT” material)
- PPP use on parcel is recorded.
The ECOPHYTO brochure on the good practices for PPP application (brochure) states the following:
Farmers should not apply PPPs when:
- Wind speed > 19 km/h or 3 on the Beaufort scale
- Temperature > 25°C
- If rain is announced within the following hours of application
When a boom sprayer is fitted with accredited low drift nozzles the non-treated safety zone (ZNT) for a given PPP can be reduced to 5 m.
A no treated zone (ZNT) to be observed along a water body (point d’eau) varies from 5 o 100 m. If no ZNT is indicated on the label, a buffer zone of 5 m minimum applies.
