Some species of fodder grasses-Bromus japonica, Chrysopogon coeruleus Danthonia cachemyriana, Eragrostis nigra, Rottboellia speciosa and Themeda triandra-in general use as cattle feed were collected in the months from July to October 1979, during the rainy season. Chlorinated organic pesticides such as HCH and DDT and their residues were estimated in dried samples of grasses by gas-liquid chromatography. All samples were found to contain HCH and DDT residues. Total HCH levels ranged from 0·156 to 0·574 mg kg-1, about 3·5 times higher than lindane levels. Total DDT levels ranged between 0·164 to 0·631 mg kg-1, and p,p′-DDT was found to be the main contaminant.
