Pesticide Residue Laboratory, Department of Agricultural Chemistry & Soil Science, Bidhan Chandra Krishi viswavidyalaya, Mohanpur-741 252 Manuscript recieved 18 November 1993 The results of photochemical and microbial transformations of some selected pesticides, carried out in our laboratory form the subject-matter of this review article. The transformations of five herbicides viz. pendimethalin, fluchloralin, oxadiazon, oxyfluorfen and butachlor as well as two insecticides, carbofuran and hydromethylnon by microbial and photochemical means resulted in the isolation and characterisation of several interesting photoand microbial metabolites. The structures of these transformation products were arrived at on the basis of spectroscopic evidence
