Abstract: 

Dissipation and translocation of terbuthylazine and metolachlor in the field in 1991 were estimated after spraying a commercial preparation and taking soil samples at fixed intervals and depths. The field trial was extended by a simple degradation study at the laboratory scale using undisturbed columns of sandy soil. In the field trial, terbuthylazine showed relatively low dissipation and translocation into the deeper soil layers. Its more mobile metabolites, desethyl-ter-buthylazine and hydroxy-terbuthylazine were detected in the deeper soil layers. The laboratory studies gave similar results, with a DT₅₀ value of about 29 d. Metolachlor had a DT₅₀ of about 13 d. Metolachlor was easily translocated through the soil. It is concluded that trials with undisturbed soil columns are a useful adjunct to field and laboratory tests.
