The experiments
summarized in this report are designed to develop data to support extension
weed management recommendations for cotton, wheat, and vegetables.
Additionally, these experiments demonstrate new and/or proven management
practices to growers, county extension personnel, agribusiness personnel, and
other extension specialist.
Replicated
experiments are established for specific needs and are located on University
stations or private farms. The experiments are a joint effort of the University
of Georgia Extension personnel, county extension personnel, cooperating
research personnel, and cooperating growers. Many commodity organizations and
chemical companies provide support of these experiments.
This publication
contains results of use patterns of herbicides, some of which may not be
registered for the particular use. Such results are included for information
purposes only and should not be taken as recommendations for use. Additionally, the University of Georgia does not guarantee nor warrant
the standards of the products, nor do they imply approval of the products to
the exclusion of others which may be similarly effective.
This research would not have been possible without
the support of the following individuals or organizations:
County Extension Agents
Will Duffie – Terrell County
Tim Flanders – Grady County
Jeremy Kichler – Macon County
Ken Lewis – Crisp County
Kevin Phillips – Wilcox County
