Confirmation of glyphosate-resistant waterhemp (Amaranthus tuberculatus) in New York
Weed TechnologyWaterhemp has become a serious management challenge for field crop growers in New York. Two putative glyphosate-resistant (GR) waterhemp populations (NY1 and NY2) were collected in 2023 from two soybean fields in Seneca County, NY. The objectives of this

Metabolic Pathway of Topramezone in Multiple-Resistant Waterhemp (Amaranthus tuberculatus) Differs From Naturally Tolerant Maize [PDF]
Frontiers in Plant Science, 2018 Waterhemp [Amaranthus tuberculatus (Moq.) Sauer] is a problematic dicot weed in maize, soybean, and cotton production in the United States. Waterhemp has evolved resistance to several commercial herbicides that inhibit the 4-hydroxyphenylpyruvate ...

Using RNA-seq to characterize responses to 4-hydroxyphenylpyruvate dioxygenase (HPPD) inhibitor herbicide resistance in waterhemp (Amaranthus tuberculatus) [PDF]
BMC Plant Biology, 2019 Background Waterhemp (Amaranthus tuberculatus (Moq.) J.D. Sauer) is a problem weed commonly found in the Midwestern United States that can cause crippling yield losses for both maize (Zea mays L.) and soybean (Glycine max L. Merr).

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 ...
