The experiments summarized in this report are designed to develop data to support extension weed management
recommendations for cotton, field corn, peanuts, grain sorghum, tobacco, and soybeans. Additionally,
these experiments demonstrate new and/or proven management practices to growers, county extension agents,
agribusiness personnel, and other extension specialists.
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 faculty, county extension
agents, cooperating research personnel, and cooperating growers. Commodity organizations, seed/chemical
companies provide financial 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 informational 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.
