Managing Herbicide-Resistant Palmer Amaranth (Amaranthus palmeri) from West Tennessee with Sequential Applications of Dicamba with and without Glufosinate

Weed Technology
Palmer amaranth has become one of the most problematic weeds in row crop production in the Midsouth. With increasing resistance to multiple herbicides, new control methods are needed. Field experiments were conducted in 2024 and 2025 at four locations in

Comparison of a diflufenican-containing premixture to current commercial standards for residual Palmer amaranth (Amaranthus palmeri) and waterhemp (Amaranthus tuberculatus) control

Weed Technology
With Palmer amaranth and waterhemp evolving resistance to nine and six different sites of action (SOAs) globally, soybean producers continue to search for new options to control these problematic weeds.

Investigation of Palmer Amaranth (Amaranthus palmeri) Resistance to Glufosinate in Mississippi

Journal of Agricultural Science
One of the most critical issues for weed scientists today is the management of herbicide-resistant weeds. Herbicide-resistant Palmer amaranth [Amaranthus palmeri (S.) Watson] is the most problematic pest problem for corn (Zea mays L.), cotton (Gossypium hirsutum L.), and soybean (Glycine max (L.) Merr.) producers in Mississippi. Greenhouse research was

Competition of Palmer Amaranth and Corn Under Different Irrigation Regimes

Agronomy
Water stress and weed competition emerge as pivotal stressors during the development of corn. This two-year study evaluated the effect of Amaranthus palmeri (AMAPA) on corn at varying densities (1, 2, and 4 plants per m−1) under two different irrigation (full and deficit) regimes.

Mechanism of Resistance of Evolved Glyphosate-Resistant Palmer Amaranth (Amaranthus palmeri)

Journal of Agricultural and Food Chemistry, 2011
Evolved glyphosate resistance in weedy species represents a challenge for the continued success and utility of glyphosate-resistant crops. Glyphosate functions by inhibiting the plant enzyme 5-enolpyruvylshikimate-3-phosphate synthase (EPSPS). The resistance mechanism was determined in a population of glyphosate-resistant Palmer amaranth from Georgia ...

Interference of Palmer amaranth in corn

Weed Science, 2001
Abstract Palmer amaranth (Amaranthus palmeri) is a major weed in corn (Zea mays) fields in the southern Great Plains of the United States. Field studies were conducted in 1996, 1997, and 1998 near Garden City, KS, to evaluate the effects of Palmer amaranth density and time of emergence on grain yield of irrigated corn and on seed production of Palmer ...

Palmer Amaranth Interference and Seed Production in Peanut

Weed Technology, 2007
Studies were conducted to evaluate density-dependent effects of Palmer amaranth on weed and peanut growth and peanut yield. Palmer amaranth remained taller than peanut throughout the growing season and decreased peanut canopy diameter, although Palmer amaranth density did not affect peanut height.
