Welcome to the University of Georgia Weed Science Homepage. 2022 Peanut/Field Corn/Soybean Weed Control Recommendations
2021 Field Corn Herbicide Harvest Restrictions for Silage/Forage
UGA Programs for Controlling Ryegrass and Wild Radish in 2019/2020 Wheat
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. 2020 Palmer Amaranth Control in Georgia Cotton – Back to the Basics
Cotton weed control has become dynamic and complex with the greatest challenges being 1) mitigating
off-target herbicide movement and 2) minimizing the development of more herbicide resistance. Our circular is designed to assist with improved,
economically-sound management programs, minimize cotton injury, and make on-target pesticice applications.
2020 Vegetable Fumigant Systems For Plasticulture in Georgia
Effective alternatives to methyl bromide exist but selecting the ideal fumigant, mulch, and herbicide
program is challenging. Growers must 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 system for their farm. 2020 Weed Control Programs for Broccoli, Cabbage, and Cauliflower
Crop rotation, tillage, and a sound herbicide program are all often critical components for long-term
success. This circular focuses on developing sound herbicide programs while minimizing crop injury
for the following production systems: 1) transplanting into bareground, 2) seeding into bareground,
and 3) transplanting into mulch. UGA Weed Control Programs for Watermelon in 2020
Crop rotation, tillage, and a sound herbicide program all influence
success. This circular focuses on developing sound herbicide programs while minimizing crop injury
when 1) transplanting into small-bed flat mulch, 2) transplanting into bareground,
and 3) seeding into bareground. UGA Weed Control Programs for Sweet Potato in 2019
Crop rotation, tillage, and a sound herbicide program are all critical components for long-term success.
This circular focuses on developing sound herbicide programs while minimizing crop injury for transplant
sweet potato production systems. Specialty Crop Visual Sensitivity Scale for 2,4-D and Dicamba for 2018
Download specialty crop visual sensitivity scale for 2,4-D and Dicamba . . . UGA Weed Control Programs for Yellow and Zucchini Squash in 2019
Crop rotation, tillage, and a sound herbicide program are all critical components for long-term
success. This ciruclar focuses on developing sound herbicide programs while minimizing crop injury
for production systems including: 1) seeding into bareground, 2) transplanting into bareground,
and 3) transplanting into mulch. 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.
