Welcome to the University of Georgia Weed Science Homepage. 2025 Peanut/Field Corn/Soybean Weed Control Recommendations
UGA Programs for Controlling Ryegrass and Wild Radish in 2024/2025 Wheat
Ryegrass is the greatest weedy threat to grain production in Georgia. Ryegrass resistant to
Osprey, PowerFlex, Axial XL, and Hoelon is spreading rapidly. Aggressive resistance
management programs must be implemented or this weed will eliminate grain production in a field. 2025 Weed Management Programs for Broccoli, Cabbage, and Cauliflower
Cultural, mechanical and herbicidal weed management are all critical components for long-term
success. This circular focuses on maximizing weed control while minimizing crop injury
for the following production systems: 1) transplanting into bareground, 2) seeding into bareground,
and 3) transplanting into mulch. 2025 Cotton Weed Control in Georgia
Control Palmer amaranth, tropical spiderwort, nutsedge and grasses while
maintaining effective pesticide stewardship.
2025 Weed Management Programs for Leafy Greens (Collard, Kale, Mustard, Turnip)
Weeds compete with the crop for light, water, nutrients, and physical space
while often harboring troublesome insects and diseases. This ciruclar focuses on cultural, mechanical, and herbicidal weed management for
production systems including: 1) seeding into bareground, 2) transplanting into bareground,
and 3) transplanting into mulch. 2025 Weed Control Programs for Yellow and Zucchini Summer Squash
Crop rotation, tillage, and a sound herbicide program are all critical components for a successful production system.
This ciruclar focuses on maximizing weed control while minimizing crop injury
for production systems including: 1) seeding into bareground, 2) transplanting into bareground,
and 3) transplanting into 'old' mulch. 2025 Sweet Potato Weed Control Programs for Georgia Farmers
Crop rotation, tillage, and a sound herbicide program are all critical components for a successful production system.
This circular focuses on implementing sound management programs while minimizing crop injury when transplanting
sweet potato. 2025 Watermelon Weed Control Programs
Crop rotation, tillage, and a sound herbicide program are all critical components for a
successful watermelon production system. This circular focuses on minimizing crop injury while maximizing weed control and yield
for the following production systems: 1) transplanting into bareground, 2) seeding into bareground,
and 3) transplanting into mulch. 2021 Field Corn Herbicide Harvest Restrictions for Silage/Forage
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. Specialty Crop Visual Sensitivity Scale for 2,4-D and Dicamba for 2018

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.
