Certain pesticides have an aquatic buffer zone requirement.  LERAP offers benefits to both the operator and the environment, by allowing a reduction of pesticide buffer zones, according to the specific situation, protecting aquatic life from products that pose the greatest risk.  

If a restriction applies, this will be detailed on the product label, along with the category.  If you want to reduce this aquatic buffer zone, there is a legal obligation to carry out and record a LERAP. 

If there is no buffer zone requirement stated on you product’s label for use near a watercourse, or there is no watercourse adjacent to the spray site, then the LERAP scheme DOES NOT APPLY. 

LERAP category A – Buffer zone cannot be reduced.

LERAP category B – Buffer zone may be reduced following LERAP assessment.
