LERAPS Guide - Horizontal Boom Sprayers (PB5621)

Record Keeping

Extra paperwork can be a burden, but this can be reduced as follows:

  • If the watercourse is a dry ditch, you may use and record an unsprayed buffer zone width of 1-metre for all pesticides covered by the LERAP scheme regardless of the rating of the sprayer.
  • If using LERAP-Low Drift 3-star equipment for category B products only, use and record an unsprayed buffer zone width of 1-metre regardless of the width of the watercourse.
  • If applying a product at 1/4 of the maximum dose rate for category B products only, record a buffer zone width of 1-metre regardless of the width of the watercourse.
  • If applying the same pesticide, at the same dose rate, using the same equipment on subsequent sprays in the same area, there is no need to recalculate the LERAP unless the width of the watercourse changes but you must still record the spray operation and the LERAP decision.
  • If you want to stick to the standard 5-metre unsprayed buffer zone rather than using a LERAP to reduce it, just make a single entry of this LERAP decision in the spray records for that area.
