Chemical Classification Of Pesticides. Hazardous substances classification. Chemical pesticides are further subdivided into organochlorine organophosphate carbamate and pyrethroids. Pesticides can be grouped in a number of different ways. On chemical composition pesticides are classified into four main groups namely.
Based on toxicity of pesticides WHO classified them into four classes. The chemical based classification of pesticides is rather complex. In general a pesticide is a chemical or a biological agent such as a virus bacterium antimicrobial or disinfectant that deters incapacitates kills pests. More detail on this a little later in this section.

This document sets out a classification system to distinguish between the more and the less hazardous forms of selected pesticides based on acute risk to human health that is the risk of single or multiple exposures over a relatively short period of time. Their target the pests they control their mode of action the way they control the pest their chemical structure their method of application the timing of their application 9. Pesticides are also divided into groups according to their chemical structure for example. 4 The WHO Recommended Classification of Pesticides by Hazard The classification is based primarily on the acute oral and dermal toxicity to the rat since these determinations are standard procedures in toxicology.
