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).

Confirmation of glyphosate-resistant waterhemp (Amaranthus tuberculatus) in New York

Weed Technology
Waterhemp 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

Automated approaches for the early stage distinguishing of Palmer amaranth from waterhemp

Frontiers in Agronomy
Palmer amaranth and waterhemp are two invasive pigweed species, which have become most troublesome to crops, especially corn and soybean. Among these two weed species, Palmer amaranth is more harmful to crops as it can grow faster, spread rapidly, and ...

Influence of glufosinate mixtures on waterhemp control and soybean canopy and yield

Weed Technology
Glufosinate serves as both a primary herbicide option and a complement to glyphosate and other postemergence herbicides for managing herbicide-resistant weed species.

A system approach for waterhemp (Amaranthus tuberculatus) management in soybean–sugar beet rotation

Weed Technology
Effective waterhemp management in crop rotations that include sugar beet requires a proactive approach, starting with robust weed management in the preceding crop.

Evaluation of single versus multiple site of action preemergence herbicides for waterhemp and giant ragweed control in Wisconsin soybean

Agrosystems, Geosciences & Environment
The use of preemergence (PRE) herbicides with soil residual activity is recognized as an effective strategy for early‐season weed management in Midwest US soybean [Glycine max (L.) Merr.] production. The efficacy of soybean PRE herbicides with single and

Effect of tillage and corn row spacing on common waterhemp growth and fecundity [PDF]

, 2003
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 ...

Mapping of flumioxazin tolerance in a snap bean diversity panel leads to the discovery of a master genomic region controlling multiple stress resistance genes [PDF]

Frontiers in Plant Science
IntroductionEffective weed management tools are crucial for maintaining the profitable production of snap bean (Phaseolus vulgaris L.). Preemergence herbicides help the crop to gain a size advantage over the weeds, but the few preemergence herbicides ...

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
