Abstract

Pesticide residues in New Zealand wool; reducing the level.

Abstract

The use of sheep dips in New Zealand to control insect pests including lice and Lucilia cuprina is described, and trends in pesticide usage are discussed. It is reported that farmers may be dipping too close to shearing time, thus exposing shearers to unacceptable levels of organophosphorus and pyrethroid insecticide residues. Advice on the timing of dipping and other aspects of good practice in insecticide use and effective pest control are given for farmers. The activities that made up the Wools of New Zealand 1994-95 insecticide residue reduction campaign are described.
