Their utility was in preventing soil erosion and improving soil health but not in significantly reducing weed populations. However, Dr. Swanton has had to re-think […]
There is some confusion on the approach for managing glyphosate resistant Canada fleabane in soybeans. I provide two scenarios that have been often asked this past winter and their solutions based on the learnings of Dr. Peter Sikkema’s applied research program out of the University of Guelph (Ridgetown campus). Scenario # 1: No-till soybeans with […]
With an increase in the number of confirmed populations of glyphosate resistant Canada fleabane in Ontario, many are looking for ways to control these populations and to eliminate any seed production. Management options in soybeans have been discussed in an earlier post, but with weed control in cereal crops imminent it is worth reviewing the […]
