Keep key pesticide handling in mind, including:


  • Avoid spraying/pelleting within 6 metres of all watercourses
  • Avoid spraying/pelleting when heavy rain is forecasted in the next 3 to 5 days
  • Avoid spraying/pelleting when field drains are flowing
  • Clean up spills quickly and responsibly by disposing of waste correctly i.e. don’t wash spills down the closest drain.
  • Wash down sprayer and slug pellet applicator equipment in fields where possible.
  • Brush down pellet applicators in fields away from watercourses and gateways to avoid carrying pellets onto hard surfaces where runoff can occur easily.



Please follow the Metaldehyde Stewardship Group guidelines wherever possible:

§  Use minimum active per ha to avoid drainage and run-off losses

§  Maximum application rate 210g metaldehyde a.s/ha* For additional protection of water, suppliers/BASIS advisors may recommend rates reduced to 160g a.s/ha or less*

§  Maximum total dose from 1st August to 31st December: 210g metaldehyde a.s/ha* For additional protection of water, suppliers/BASIS advisers may recommend rates reduced to 160g a.s/ha or less*

§  Maximum total dose rate: 700g metaldehyde a.s/ha/calendar year*

§  No pellets to be applied within six metres of a watercourse**

§  Do not apply when heavy rain is forecast

§  If drains are flowing do not apply metaldehyde based slug pellets

NB: a.s.: active substance (or active ingredient)

* from any combination of metaldehyde products. 700g is also the statutory limit.

**The Metaldehyde Stewardship Group are currently recommending a 10m volountary buffer from any field boundary including hedges. This is set to become mandatory by Autumn 2018.  


Nutrients and sediment


Diffuse pollution can also be in the form of sediments and nutrients such as nitrates and phosphorus.  These nutrients can result from agriculture and also a number of other sources such as sewage treatment works, transport and industrial sites. These nutrients and sediments can lead to the nutrient enrichment, and oxygen depletion of a watercourse which can have adverse effects on the aquatic ecosystem.  


Some basic actions include:

  • Ensure manures are used appropriately by analysing what nutrients are present so that land is not overloaded with nutrients that can leach or runoff easily.
  • Maintain your soil structure at a good standard (see the EA Think Soils booklet for further advice), this will promote rain infiltration into soil which in turn will avoid soil runoff and erosion and therefore the sedimentation of watercourses will be reduced.

·       Avoid compaction from machinery and livestock by reducing the number of passes carried out over land, reducing tyre pressures to spread the load weight and reducing stock numbers on vulnerable fields that are close to watercourses.
