Control and Distribution of Herbicide Resistant Waterhemp (Amaranthus tuberculatus) in Ontario [PDF]
, 2019 Field surveys were conducted in 2016, 2017 and 2018 to build on previous distribution research. Waterhemp was located at 42 additional locations in seven Ontario counties and the province of Quebec. Greenhouse testing of populations collected between 2014 and 2017 has shown that 100% of the populations are resistant to Group 2 herbicides, 83% to Group ...

Effect of tillage and corn row spacing on common waterhemp growth and fecundity [PDF]
, 2020 The acceptance of integrated weed management programs has been hindered by a lack of information on crop-weed interactions. Four experiments were conducted in central Iowa during 2001 and 2002 in corn planted in 38 and 76 cm rows to determine the response of common waterhemp (Amaranthus rudis Sauer) growth parameters to corn (Zea mays) row spacing and ...

Influence of glufosinate mixtures on waterhemp control and soybean canopy and yield
Weed TechnologyGlufosinate serves as both a primary herbicide option and a complement to glyphosate and other postemergence herbicides for managing herbicide-resistant weed species.

Glyphosate- and multiple-resistant waterhemp (Amaranthus tuberculatus var. rudis) in Ontario, Canada [PDF]
Canadian Journal of Plant Science, 2017 Waterhemp is one of the most troublesome weeds in the US and is spreading into Ontario. In 2014, a waterhemp population was not controlled with glyphosate in a field in Lambton County, Ontario. This population was the first confirmed glyphosate-resistant (GR) waterhemp in Canada.

Changing landscape of waterhemp herbicide resistance in Wisconsin: a comparative analysis over time
Weed TechnologyA comprehensive assessment of herbicide resistance in waterhemp accessions to herbicides commonly used on corn and soybean over time is crucially necessary for documenting shifts in herbicide resistance patterns and identifying effective management ...
