Abstract This document presents the latest WHO recommendations with respect to the classification of pesticides. Part I describes the basis of the WHO system for the classification of pesticides according to their acute risk to health. The classification is based primarily on the acute oral and dermal toxicity to the rat (LD50 values): extremely hazardous, highly hazardous, moderately hazardous and slightly hazardous. The application of the criteria for classification is explained along with the effects of classification on labelling. Part II provides lists of products in the four hazard classes and a list of pesticides considered unlikely to present acute hazard in normal use. Further tables are provided for determining the hazard class of a formulation. Update of CIS 03-360.
