Aspects of the Allelopathic Potential of Horseweed (Conyza albida)
International Journal of Agricultural Research, 2007 The allelopathic effects of three plant tissues of Conyza albida (stems, leaves and inflorescences) on oat growth were further investigated using in vivo tests. Oat growth (fresh and dry weights of above and underground parts) was significantly inhibited from phytotoxic activity of upper leaves and inflorescence tissues of C. albida in pot experiments.

Response of Nebraska Horseweed (Conyza canadensis) Populations to Dicamba
Journal of Agricultural Science, 2013 Dicamba-resistant soybeans are being developed to provide an additional herbicide mechanism-of-action for postemergence weed control in soybean. Numerous broadleaf species, including horseweed, have evolved resistance to glyphosate. It is anticipated that dicamba will be used by farmers as a primary tool to manage these weeds.

The intensity of non-target site mechanisms influences the level of resistance of sourgrass to glyphosate [PDF]
, 2014 Non-target site mechanisms are involved in the resistance of sourgrass (Digitaria insularis) to glyphosate. Studies on the 14C-glyphosate absorption and translocation as well as the detection of glyphosate and its metabolites in sourgrass plants were ...
