Title: Use of Pesticides at two Watercress Farms in Hampshire : A report into the use of
Author: National Rivers Authority Southern Region
Document Type: Monograph
Abstract:
Use of pesticides is carefully regulated by the Food and
Environment Protection Act (1985). Only approved compounds may
be used, and then only under the conditions and for the purposes
specified on the approved product label. Allowance is made,
however, for use on other crops by means of an Off Label
Approval (OLA) which is usually granted for a specified time
period.
The pesticides malathion and dimethoate, together with the three
fungicides, were granted off label approval by MAFF until
September 1990 subject to various restrictions. After the expiry
of this approval, crops sprayed in the course of this
investigation were subsequently destroyed.
The watercress industry feels that continued use of these
products is essential to their operation. It was agreed that a
study would be carried out by the National Rivers Authority, in
conjunction with Hampshire Watercress Ltd. The objective was to
determine whether significant levels of malathion and dimethoate
are detectable in the receiving water downstream of the cress
beds after spraying, and whether the macroinvertebrate
populations of the river are affected. This report details the
results of the investigation.
