Control of Multiple Herbicide-Resistant Palmer Amaranth in Enlist Corn
, 2020 Recent evolution of multiple herbicide resistant (MHR) Palmer amaranth [resistant to 2,4-D, glyphosate (Roundup), chlorsulfuron (Glean), atrazine (Aatrex), and mesotrione (Callisto)] is a serious threat to newly developed stacked trait technologies ...

Influence of Carrier Volume and Nozzle Selection on Palmer Amaranth Control
Peanut Science, 2014 ABSTRACT Palmer amaranth is one of the most troublesome weeds in the southeast. Effective control is essential in order to avoid reductions of crop yield. Due to widespread resistance to acetolactate synthase (ALS)-inhibiting herbicides, postemergence contact herbicides are often the only in-season option to control Palmer amaranth in ...

Update on Palmer Amaranth in Conservation Plantings
, 2017 The 2016 growing season will be remembered by many for the widespread detections of Palmer amaranth across Iowa. While native seed mixes contaminated with Palmer amaranth seed used in Conservation Reserve Program (CRP) fields were the largest source of ...

Automated approaches for the early stage distinguishing of Palmer amaranth from waterhemp
Frontiers in AgronomyPalmer amaranth and waterhemp are two invasive pigweed species, which have become most troublesome to crops, especially corn and soybean. Among these two weed species, Palmer amaranth is more harmful to crops as it can grow faster, spread rapidly, and ...

Characterization and Management of Auxin-Resistant Palmer amaranth in Tennessee
, 2022 Palmer amaranth has a long history of evolving resistance to herbicides to the point it has become a significant row crop production obstacle. Cotton and soybean growers were offered new technologies in 2016, expanding in-crop herbicide options to ...

Identifying waterhemp and Palmer amaranth
, 2013 Several people have submitted images of escaped "pigweeds" wondering whether the plants were Palmer amaranth. In all cases, except the earlier reported situation in Harrison County, the plants in question have been waterhemp, although at casual glance ...
