Potential use of preharvest applications of glyphosate in canola (Brassica rapa L.) in western Canada both as a harvest aid and to control weeds prompted this study. Experiments were conducted from 1988 to 1990 at four locations in the region to docu

Residue data for glyphosate and its major metabolite aminomethylphosphonic acid (AMPA) in canola seed following preharvest application of glyphosate were lacking when this 2-yr study was initiated. Residues of glyphosate and AMPA were measured in the

The effectiveness of preharvest applications of glyphosate on yellow toadflax was evaluated at five sites in Alberta from 1992 to 1994. At each site, glyphosate at 0.9 to 1.8 kg ae/ha was applied with or without nonionic surfactant and/or ammonium su
