Response of Palmer Amaranth and Sweetpotato to Flumioxazin/Pyroxasulfone
Weed Technology, 2018AbstractStudies were conducted to determine the tolerance of sweetpotato and Palmer amaranth control to a premix of flumioxazin and pyroxasulfone pretransplant (PREtr) followed by (fb) irrigation. Greenhouse studies were conducted in a factorial arrangement of four herbicide rates (flumioxazin/pyroxasulfone PREtr at 105/133 and 57/72 g ai ha–1,S ...

Palmer Amaranth in the Pacific Northwest
Crops & SoilsAbstractPalmer amaranth is one of the most troublesome pigweeds in crop production systems in the United States. It only recently started to appear in the Pacific Northwest (PNW). A coordinated extension and outreach effort among land grant universities (University of Idaho, Oregon State University, and Washington State University), Amalgamated Sugar ...

Allelochemicals from palmer amaranth,Amaranthus palmeri S. Wats
Journal of Chemical Ecology, 1987The presence of Palmer amaranth (AMAPA) residues in the soil reduced fresh weight accumulation in onions and carrots and markedly decreased seedling field establishment of carrots. Solid-phase separation techniques were used to isolate fractions containing water-soluble organic compounds from AMAPA residues and soil amended with such residues.

Sweetpotato Tolerance and Palmer Amaranth Control with Metribuzin and Oryzalin
Weed Technology, 2017Field studies were conducted in Clinton, NC in 2007 and 2009 to determine sweetpotato crop response and Palmer amaranth control with metribuzin and oryzalin. Treatments consisted of 140 and 202 g ai ha−1metribuzin applied immediately after transplanting [0 wk after transplanting (WAP)] or 2 WAP, 560 and 1121 g ha−1oryzalin 0 WAP, and tank mixes of ...

Positive and normative modeling for Palmer amaranth control and herbicide resistance management
Pest Management Science, 2017AbstractBACKGROUNDDynamic optimization models are normative; they solve for what growers ‘ought to do’ to maximize some objective, such as long‐run profits. While valuable for research, such models are difficult to solve computationally, limiting their applicability to grower resistance management education.

Prevention and Control of Palmer Amaranth in Cotton
2020Palmer amaranth (Amaranthus palmeri), a member of the "pigweed" family, is one of the most troublesome weeds in many southern row crops. Seed can germinate all season and plants can grow to over 6 feet in height. Plants have either male flowers that shed pollen or female flowers that can produce up to 600,000 seed per plant.
