Sorption of acetanilide herbicides on soils and its correlation with soil properties. Sorption of acetanilide herbicides, metolachlor, acetochlor, pretilachlor and butachlor on eight soils with various physical and chemical properties was studied. The adsorption isotherms could fit Freundlich equation (r2>=0.91), and the adsorpt...

The alkaline degradation of propanil, propachlor and pronamide [propyzamide] were shown by HPLC to result in hydrolysis rates of 0.0154, 0.1466 and 0.4966 M/h, resp. Ames tests with undegraded and half-degraded propanil (2-400 mg/litre) showed tha...

The degradation of 14C-labeled metolachlor, acetochlor, and pretilachlor in control and soils with 10-yr metolachlor- history or 3-yr butylate history was studied by monitoring the evolution of 14CO-2 in soil biometer flasks. The degradation rate...
