The persistence in soil of trifluralin 545 EC, trifluralin 5 G, and ethalfluralin 360 EC was studied over a 2-yr period at three different sites in Saskatchewan. At two of the three sites both formulations of trifluralin were more persistent than ethalfluralin when a canola crop was grown in the treated soil. In the high organic matter soil at the third site the persistence of trifluralin and ethalfluralin was similar under both fallow and cropped conditions. Crop response data gathered from… Expand
