Abstract
The incorporation of 0·5 per cent sodium carboxymethyl cellulose in malathion sprays resulted in markedly improved persistence of the residual film on an alkaline, cement substrate. At this concentration the effective residual life was prolonged from less than 4 wk for water-dispersible powder and less than 1 wk for emulsion to 14 wk for both formulations. This improvement is attributed partly to the absorption of both malathion and hydroxyl ions by the cellulose, thus preventing their interaction and consequent breakdown of malathion, and partly to a reduction in absorption into the porous substrate.
