Welcome to the University of Georgia Weed Science Homepage. Methyl Bromide Alternatives 2015
Effective alternatives to methyl bromide exist but selecting the ideal fumigant, mulch, and herbicide
program is challenging. Growers must better understand how soil texture, moisture, bed compaction, and
their cultural practices influence fumigant activity, planting intervals, and off-gassing concerns.
This circular is provided to assist growers with developing the most effective fumigant system for their farm UGA Weed Control Programs for Wheat in 2015
Ryegrass threatens Georgia wheat production, with numerous populations resistant to Osprey, PowerFlex,
Axial and Hoelon. Aggressive resistance management programs must be implemented to ensure long-term
sustainability of grain production. UGA Weed Control Programs for Watermelon in 2015
New herbicidal tools are being developed to assist growers in the battle against weeds in watermelon.
These tools are a result of cooperative efforts involving The University of Georgia, IR-4, The Georgia
Department of Agriculture, The Georgia Agricultural Commission for Vegetables, and Industry. This circular
is an effort to provide effective weed management programs for seeded and transplant watermelon. UGA Programs for Controlling Palmer Amaranth in 2015 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.
Rolling Rye For Conservation Tillage Cotton Success 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. 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.
