The effect of corn-cob controlled-release formulations (CRF) of thiobencarb (TAl and TA2) and alginate CRF(TAL 70192) to the freshwater shrimp, Macrobrachium lanchesteri (De Man), in comparison to a conventional granular formulation was studied in the laboratory. Mortality of the shrimps 24 h after exposure to the conventional formulation was significantly higher (P < 0.05), and increased to 93.3% after 120 h. The CRF of TAl, TA2 and TAL 70192 caused mortality of 19.2, 5.8 and 8.5%, respectively, 120 h after exposure. Thisdifference is due to the slower release of thiobencarb using CRF.
