The quality of six commercial grade pesticide granule carriers namely attapulgitc, bentonite, China clay, gypsum, soapstone and talc, was adjudged by differential thermal analysis and specific surface area measurement. Most of these were found to contain impurities. Their physico-chemical characteristics namely bulk density before and after compaction, particle density, sorptivity, cation exchange capacity, pH, pKa and flowability are reported.
