UGA Programs for Controlling Palmer Amaranth in 2014 Cotton
It is imperative that growers continue to use
sound herbicide programs but also
integrate these programs with other control
measures, such as hand-weeding, to remove
escapes before seed are produced, deep turning
to reduce the number of plants emerging (ideally
wait 3.5 to 4 years before repeating), and/or
using a heavy mulch cover crop to suppress
emergence in conservation tillage systems.
These integrated programs proved to be very
successful during 2012. Continued efforts are
underway to further improve management
programs while becoming more economical.

The Biology and Ecology of Palmer Amaranth: Implications for Control
Palmer amaranth is a highly competitive weed of field corn, cotton, peanut, and soybean and has been confirmed to be
resistant to glyphosate in nearly every agronomic county in GA. Glyphosate-resistant (GR) Palmer
amaranth’s establishment and spread has been assisted by its rapid growth rate, extensive rooting structure, high seed
production, physical seed movement (man, animal, water), and most importantly by pollen (wind) dispersal.
Growers
must understand the biology and ecology of GR Palmer amaranth if effective control is to be achieved.

University of Georgia Herbicide Programs for Tropical Spiderwort Control in 2013 Cotton
Tropical spiderwort is a noxious, exotic, invasive
weed that can spread quickly. Upon initial
observation, tropical spiderwort appears to be a grass. While not a grass, it is a monocot (in
contrast to broadleaf weeds, which are dicots) with
leaves and stems usually fleshy and succulent. The
stems will creep along the ground and root at the
nodes. Vegetative cuttings from stems are capable
of rooting and reestablishing following cultivation.
Tropical spiderwort will produce seed above and
below ground.
