Abstract

A field study was carried out to investigate persistence and degradation kinetics of trifluralin (48 EC) applied pre emergently in Black gram (Variety B-76) @ 1 Kg ai ha^-1 (T₁) and 2 Kg ai ha^-1 (T₂) for the control of broad leaf weeds during kharif 2005. The dissipation on 90 days was around 97% in T₁ and T₂. Kinetics studies revealed that dissipation of trifluralin residues followed first order kinetics. The half life values observed were 23.3 days in T₁ and 26.2 days in T₂. Irrespective of any dose no residues were detected in cropped soil as well as plant samples at harvest.
