Determination of the Mechanisms of MCPA Resistance in <i>Amaranthus powellii</i>. [PDF]
Plant DirectABSTRACT Resistance to 2‐methyl‐4‐chloro‐phenoxyacetic acid (MCPA) was recently confirmed in a population of green pigweed (Amaranthus powellii) from Dresden, Ontario, Canada, with a resistance factor of 4.4. Resistance to synthetic auxin herbicides in Amaranthus species has previously been linked to non‐target site resistance mechanisms with low‐level

Gene Duplication and Aneuploidy Trigger Rapid Evolution of Herbicide Resistance in Common Waterhemp [PDF]
Plant Physiology, 2018 An increase in gene copy number is often associated with changes in the number and structure of chromosomes, as has been widely observed in yeast and eukaryotic tumors, yet little is known about stress-induced chromosomal changes in plants. Previously, we reported that the EPSPS (5-enolpyruvylshikimate-3-phosphate synthase) gene, the molecular target ...

Herbicide Programs for Waterhemp Control in Soybean [PDF]
, 2021 Waterhemp is a dioecious (male and female flowers on separate plants) pigweed with a high genetic diversity. Consequently, this pigweed has a high propensity to adapt to control tactics and has evolved resistance to herbicides from as many as 6 or 7 ...

Performance of Preemergence Herbicides on Waterhemp Control in Soybean [PDF]
, 2020 The battle against waterhemp is complicated mainly because of its extended emergence period (early May until August). Preemergence (PRE) soil residual herbicides serve as a foundation for managing waterhemp, but require follow-up treatments with ...

Managing herbicide-resistant waterhemp (Amaranthus tuberculatus) in Midwestern United States soybean systems [PDF]
, 2023 Weed infestations, namely herbicide-resistant waterhemp (Amaranthus tuberculatus [Moq.] J.D. Sauer) prevent growers from achieving optimal yields; therefore, growers are seeking tactics to reduce or prevent crop-weed competition.

Layered‐residual herbicide programs for waterhemp control in glufosinate‐resistant soybean
Crop, Forage & Turfgrass Management, 2023 Core Ideas Glufosinate is an important POST herbicide for waterhemp control in glufosinate‐resistant soybean. The layered‐residual herbicide approach improved season‐long waterhemp control. Glufosinate POST combined with layered soil residual herbicides improved season‐long waterhemp control.
