Abstract Two trials were established in 2001 and 2002 at Ridgetown, Ontario, to determine the effects of residues from chlorimuron-ethyl applied post-emergence (POST) to soybean on cabbage, potato, tomato, and sweet corn grown 1 year after application (i.e. 2002 and 2003). Treatments included an untreated control and chlorimuron-ethyl applied POST at 9 and 18 g ai ha −1 , representing the label dose and twice the label dose in soybean compared with an untreated control. There were no visible injury symptoms at 7, 14, and 28 days after emergence (DAE) and no adverse effects on shoot dry weight and yield in any of the vegetable crops 1 year after chlorimuron-ethyl was applied. Cabbage, potato, tomato, and sweet corn showed excellent tolerance to POST applications of chlorimuron-ethyl applied to soybean in the previous year under the environmental conditions experienced in this study.
