The implementation of scouting programmes to detect the presence of the species in agricultural land, including drainage systems, before fully reproductive is recommended. Considering that A. palmeri is originally from arid and desert habitats, its wide distribution is indicative of the phenotypic plasticity of the species (Ward et al., 2013). The leaves exhibit diaheliotropic movements, which helps the species to have high photosynthetic capacity. It is an opportunistic weed with the ability to outcompete other species partly due to being able to germinate throughout the season, a rapid growth rate and prolific seed production (Ehleringer, 1983). EPPO, 2020. Flora of North America North of Mexico. De Andrade Jr ER , Cavenaghi AL, Guimarães SC, 2015. Weed Technology, 21(2), 567-570. A new herbicide-resistant strain of Amaranthus palmeri has appeared; it is glyphosate-resistant and so cannot be killed by herbicides using the chemical. Euro+Med PlantBase - the information resource for Euro-Mediterranean plant diversity. Grain sorghum is the sixth most common crop in the United States, being grown on 1.2 million ha in 2016 ().As with all crop production, competition with weeds is among the top yield reducers for grain sorghum (Thompson et al. Beltsville, Maryland, USA: National Germplasm Resources Laboratory. The website also provides access to a database and images of herbarium specimens found at the University of South Florida and other herbaria. Integrating cover crops and POST herbicides for glyphosate-resistant Palmer amaranth (Amaranthus palmeri) control in corn. The PRE herbicide application of combinations such as S-metolachlor + flumioxazin or flumioxazin + pyroxasulfone, followed by fomesafen is also recommended. Palmer amaranth considerably exceeded common waterhemp (Amaranthus rudis), redroot pigweed (A. retroflexus), and other Amaranthus species in height, dry weight, and leaf area in comparative growth analyses conducted under field conditions in Kansas (Horak and Loughin, 2000) and Missouri (Sellers et al, 2003). Deep tillage in autumn followed by a cover crop is also recommended as germination and seedling establishment of A. palmeri is significantly reduced when the seeds are buried at depths of 5 cm or more in the soil (EPPO, 2019).

St Paul, Minnesota, USA: Minnesota Department of Agriculture.https://www.mda.state.mn.us/plants/pestmanagement/weedcontrol/noxiouslist/palmeramaranth, Missouri Botanical Garden, 2019. [4] Palmer amaranth has a tendency to absorb excess soil nitrogen, and if grown in overly fertilized soils, it can contain excessive levels of nitrates, even for humans. Although this species can be used as forage it can be poisonous to livestock due to the high concentrations of nitrates present (Schmutz et al., 1974; Burrows and Tyrl, 2013). Palmer amaranth is among the "top five most troublesome weeds" in the southeast of the United States and has already evolved resistances to dinitroaniline herbicides and acetolactate synthase inhibitors.

Toxic plants of North America, (Second Edition) . The leaves are cooked and used as a vegetable and the seeds are ground into meal for food by the Navajo and Yuma tribes (Sauer, 1957). For infestations of maize fields, the use of glufosinate with atrazine is recommended. Well drained loamy soils with slightly acidic nature and warm climate are suitable for amaranthus cultivation. Its range is also predicted to expand as a result of climate change (Kistner and Hatfield, 2018).

Amaranthus palmeri S.Watson is an accepted name This name is the accepted name of a species in the genus Amaranthus (family Amaranthaceae). [6] As a result, the primary economic importance of Palmer amaranth to American farmers has been as a noxious weed and a competitor to more marketable crops, rather than as a crop in its own right. Palmer amaranth is among the "top five most troublesome weeds" in the southeast of the United States and has already evolved resistances to … Pest Management Science.
