1095. Brown, D.B., D. McCool, R. Papendick, and L. McDonough. 1985. Herbicide residues from winter wheat plots: effect of tillage and crop management.. J. Environ. Science 14:521-532.
Studied the magnitude and persistence of residues of metribuzin and bromoxynil octanoate in winter wheat plots under various tillage management. Herbicide loss was greatest where erosion was high. Herbicide runoff was extended under winter conditions in eastern WA, and there was little movement or degradation of herbicides when the ground was frozen. The half life of metribuzin was 102-112 days.
