摘要：

Carbaryl (25. 4 kg/ha) was applied to a Congaree sandy loam fieldplot containing a shallow (about-1. 1 m) water table. Movement and loss in the soil profile, and accumulation in underlying ground water were monitored for 16 months. Rainfall during this time was 182 cm (3. 5 pore volumes based on the upper 1 m of soil). The upper 1 m contained about 6% of the applied carbaryl after 16 months. No carbaryl was found in the 0-20 cm layer after the 4th month. Loss of carbaryl with time in the upper 1 m was concentration-dependent. Time to half-concentration within the upper 1 m was less than 1 month. Carbaryl appeared in the underlying ground water within 2 months after soil application and persisted through the 8th month. Maximum ground-water concentration, about 0. 3 mu mol/liter, occurred at the end of the second month.
