Herbicide strategies for Palmer amaranth (Amaranthus palmeri) management in Illinois
Palmer amaranth has been spreading from the southern United States into the Midwest, and the extent of damage this weed can inflict to Illinois row crops is not yet known. Palmer amaranth is known for rapid biomass accumulation and multiple emergence events, making this weed difficult to control. …

Evaluating cover crops and herbicides for horseweed and Palmer amaranth management
Horseweed and Palmer amaranth are common weeds in Kansas that compete against many row crops. Horseweed can emerge in different seasons depending on the year. Palmer amaranth emerges from spring throughout the summer months and has a rapid growth rate with higher temperatures. Three separate …

The biology and management of Palmer amaranth (Amaranthus palmeri S. Wats) in Indiana
<p>Palmer amaranth is a pernicious summer annual weed that has evolved resistance to six herbicide sites of action in the U.S. and threatens agriculture production. In 2011, Palmer amaranth was identified in flood plains in two southern Indiana counties (Posey and Vanderburgh). Determining if …

Characterization of PPO-inhibitor resistance in waterhemp (Amaranthus tuberculatus) and Palmer amaranth (Amaranthus palmeri)
Waterhemp and Palmer amaranth are two of the most troublesome weed species in the Midwest. The overuse of acetolactate synthase (ALS), photosystem II, and 5-enolpyruvylshikimate-3-phosphate synthase (EPSPS) inhibitors to control these species led to the evolution of resistance to these herbicides …

Control, Assessment and Glyphosate Resistance of Palmer Amaranth (Amaranthus palmeri S. Wats) in Virginia
… been an effective mean for controlling Palmer amaranth, however overreliance on glyphosate based systems resulted in weeds that can no longer be controlled with glyphosate. Palmer amaranth resistance to glyphosate has been confirmed in ten US states including Virginia's bordering neighbor North …

Understanding gender determination in dioecious Amaranthus weeds palmer amaranth (Amaranthus palmeri) and waterhemp (Amaranthus tuberculatus)
… of dioecious weeds. Common waterhemp (Amaranthus tuberculatus (Moq.) Sauer var. rudis (Sauer) Costea and Tardif) and Palmer amaranth (Amaranthus palmeri S. Watson) are troublesome weeds of row-crop production in the United States. Their dioecious reproductive systems ensure outcrossing, …

Avoiding Protoporphyrinogen Oxidase Inhibiting Herbicide Selection Pressure on Common Ragweed and Palmer amaranth in Soybean
Palmer amaranth (Amaranthus palmeri) and common ragweed (Ambrosia artemisiifolia) can cause detrimental soybean yield loss. Due to widespread resistance to glyphosate and ALS-inhibiting herbicides, growers rely on protoporphyrinogen oxidase inhibiting herbicides (PPO) such as flumioxazin applied …

Resistance Screening and Control Options for Glyphosate-Resistant Palmer Amaranth (Amaranthus palmeri) in Cotton (Gossypium hirsutum)
<p>In the mid-2000's, glyphosate-resistant Palmer amaranth biotypes began to emerge in many southern states. In 2006, glyphosate-resistant Palmer amaranth was identified in a field in Mississippi County, Arkansas. A greenhouse experiment was conducted in 2008 to screen Palmer amaranth accessions, …

EPSPS gene duplication in Palmer amaranth: relative fitness, inheritance, and duplication mechanism of the glyphosate resistance trait
Glyphosate resistant (GR) Palmer amaranth (Amaranthus palmeri S. Wats.) is a weedy plant species that has invaded agricultural fields in at least 25 states, raising the cost of weed control to more than 4x the original cost. In most areas, the resistance is conferred through a gene amplification …

Use of Fluridone for Control of Palmer Amaranth (Amaranthus palmeri) in Cotton (Gossypium hirsutum) and on Ditchbanks
<p>Since 2006, glyphosate-resistant Palmer amaranth has been considered the most problematic weed in agronomic crops across the Midsouth. As a result of glyphosate resistance, producers began to again utilize a diverse herbicide program for management of this weed, which consists of several …

Integration of Herbicide Programs with Cultural and Mechanical Practices for Managing Glyphosate-Resistant Palmer amaranth (Amaranthus palmeri) in Soybean (Glycine max)
<p>Herbicide-resistant Palmer amaranth is the most troublesome weed in Arkansas row crops, causing producers to rely heavily on multiple mechanisms of action to reduce selection pressure for further evolution of herbicide resistance and to successfully produce a profitable crop. It is critical for …

Exploring the mechanisms of Palmer amaranth resistance to protoporphyrinogen oxidase-inhibitor herbicides, dynamics of gender, and management strategies
Palmer amaranth (Amaranthus palmeri S. Watson) is a C4, summer annual, dioecious broadleaf plant and is the most economically damaging and troublesome weed in major crops grown in the USA. Currently, Palmer amaranth is reported to have evolved resistance to nine herbicide sites of action, raising …
