Integrating early spring‐planted barley or oat for Palmer amaranth management in soybean

Crop Science, Volume 66, Issue 1, January/February 2026.
Abstract Fall‐planted cover crops (CCs) are widely used for weed suppression, but CC establishment challenges after fall harvest in temperate regions necessitate alternative approaches. The objectives of this study were to evaluate the integrated effect of spring‐planted barley or oat CC and herbicide programs for CC biomass production, Palmer amaranth

Optimizing metribuzin rates for herbicide-resistant Amaranthus weed control in soybean

Weed Technology
Palmer amaranth and waterhemp are troublesome weeds in U.S. corn, soybean, and cotton production systems. Rapid evolution of resistance to herbicide from multiple sites of action in these species warrant alternate weed control options. Metribuzin applied

Herbicide programs for control of a five‐way herbicide resistant waterhemp population in Xtendflex or Enlist E3 soybean

Crop, Forage &Turfgrass Management, Volume 11, Issue 2, December 2025.
Abstract Waterhemp [Amaranthus tuberculatus (Moq.) J.D. Sauer] is one of the most problematic weeds in soybean [Glycine max (L.) Merr.] production in the Midwestern United States. In recent years, the adoption of soybean resistant to dicamba, 2,4‐D, and/or glufosinate have enabled the use of these herbicides to improve control of problematic weeds ...

WATERHEMP (AMARANTHUS TUBERCULATUS) IN SOYBEAN IN KENTUCKY CONDITIONS [PDF]

, 2013
Waterhemp was a sporadic weed in Kentucky soybean production since the 1970’s. Waterhemp’s presence was not significant until the 1990’s after a widespread adoption of imazaquin and imazethapyr herbicides in the late 1980’s by Kentucky farmers which ...

A genetic and genomic study of resistance to 4-hydroxyphenylpyruvate dioxygenase (HPPD) inhibitor herbicides in Amaranthus tuberculatus (waterhemp) [PDF]

, 2001
Waterhemp (Amaranthus tuberculatus) is an agronomic weed found throughout the Midwestern United States. Without proper management waterhemp has the potential to cause yield losses up to 74% and 56% in maize (Zea mays L.) and soybean [Glycine max (L ...

Commercial sprayer efficiency for application success on targeted weeds

Weed Technology
Commercial targeted sprayer systems allow producers to reduce herbicide inputs but risks the possibility of not treating emerging weeds. Currently, targeted applications with the John Deere system have five spray sensitivity settings, and no published ...

A molecular cytogenetic perspective on chromosome biology and crop improvement

The Plant Genome, Volume 18, Issue 4, December 2025.
Abstract The age of molecular cytogenetic analysis of crop plants dawned in the late 1960s and early 1970s with new advances in the identification of somatic chromosomes by C‐banding and fluorescence in situ hybridization concurrent with advances in DNA cloning, sequencing, and mapping. In this perspective article dedicated to Ronald Phillips, I review

Responses of waterhemp and horseweed to cereal rye cover crop termination timing in soybean

Agrosystems, Geosciences & Environment
Field experiments were conducted in soybeans (Glycine max L.) to determine the effects of a cereal rye (Secale cereale L.) cover crop (CC), two CC termination timings (TTs), and four herbicide programs (HP) on the emergence, biomass, and seed production ...

Interventions for weed seed management in cotton around the harvest time

Weed Technology
Late-season escapes of Palmer amaranth and waterhemp (both are Amaranthus species) pose a significant challenge in cotton production due to their high fecundity, herbicide resistance, and ability to replenish the weed seedbank at harvest.
