Fate of sprayed formulated aminocarb in freshwater

Following simulated aerial spraying of Matacil^® in field and tank experiments, the concentration of aminocarb increased in the subsurface water for some hours: 22 h in the case of the field and 72 h for the tank. Thereafter, the concentration of Matacil^® declined exponentially in subsurface waters. The equation for this, A = 4.834 + 0.165 g ? 0.155T, can be used to predict the concentration of aminocarb in the lentic environment (A, μgL^?1), providing the application rate (g ha^?1) and time after application (T in h) are known.
