Welcome to the University of Georgia Weed Science Homepage. Methyl Bromide Alternatives 2017
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. Specialty Crop Visual Sensitivity Scale for 2,4-D and Dicamba for 2017

Crop rotation, tillage, and a sound herbicide program are all often critical components for long-term
success. This ciruclar focuses on developing sound herbicide programs while minimizing crop injury
for the following production systems: 1) transplanting into mulch, 2) transplanting into bareground,
and 3) seeding into bareground. UGA Weed Control Programs for Yellow and Zucchini Squash for 2017
Crop rotation, tillage, and a sound herbicide program are all often 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. UGA Weed Control Programs for Watermelon in 2017
Crop rotation, tillage, and a sound herbicide program are all often critical components for long-term
success. This ciruclar focuses on developing sound herbicide programs while minimizing crop injury
for the following production systems: 1) transplanting into small-bed flat mulch, 2) transplanting into bareground,
and 3) seeding into bareground.
Although new auxin technologies are increasing management options for cotton growers, the use of 2,4-D and dicamba must be limited in areas where
sensitive crops/plants are nearby. Liberty and auxin programs are similarly effective when growers are timely. Our focus with this circular is to help growers
implement sound, sustainable programs for the control of Palmer amaranth while minimizing cotton injury without the use of auxin herbicides.
2,4-D Based Weed Management Programs for 2017 Enlist Cotton
Mitigating off-target movement of 2,4-D is the greatest challenge for a 2,4-D-based weed management system. Georgia
has many areas where this herbicide should not be applied in-season; for areas where it can be applied safely, review
labels closely. Mitigating off-target movement of 2,4-D and implementing sound programs are addressed.
Dicamba-Based Weed Management Programs for 2017 XtendFlex Cotton
Mitigating off-target movement of dicamba is the greatest challenge for a dicamba-based weed management system.
Georgia has many areas where dicamba simply should not be applied; for areas where it can be applied safely, review
labels closely. Mitigating off-target movement of dicamba and implementing sound programs are addressed.
The occurrence of herbicide resistance in Palmer amaranth and other weeds in Georgia is cause for
significant concern for the agricultural industry. Changes in cropping practices, specifically the
reliance on a limited number of herbicides, have streamlined weed management. However, the consequence
has been the development of herbicide resistance. An effective herbicide-resistant weed management plan
will require the integration of multiple herbicide chemistries in an effort to minimize selection
pressure and delay the occurrence of herbicide resistance in a field. Other control strategies, such as
tillage, extreme cover crops, narrow row spacing, hand-weeding, crop rotation, and mechanical cultivation
must also be included in an herbicide resistant weed management plan. UGA Weed Control Programs for Wheat in 2015/2016
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. 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.
