Effect of Thiobencarb Formulations on Freshwater Shrimp, Macrobrachium lanchesteri (De Man)
Omar, Dzolkhifli and Mohamad, Rosli (1996) Effect of Thiobencarb Formulations on Freshwater Shrimp, Macrobrachium lanchesteri (De Man). Pertanika Journal of Tropical Agricultural Science, 19 (2/3). pp. 205-207. ISSN 0126-6128
The effect of com-cob controlled-release formulations (CRF) of thiobencarb ( TAl and T A2) 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 ofthe 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. This difference is due to the slower release of thiobencarb using CRF.
