The Small Impoundments Technical Committee is planning to host an aquatic plant workshop at the 2023 SDAFS annual meeting. Our goal is to provide identification as well as up-to-date control information for the most problematic aquatic species we are faced with within the Southeast. By polling SDAFS representatives from each state, we have developed a list of the top 23 problematic aquatic plants in southeastern impoundments. As new products and techniques are being used to control aquatic vegetation in both private and public water bodies in the Southeast, the informational literature is outdated. Therefore, we are polling professional applicators across the Southeast to gather more up-to-date control information that can be available to applicators. Please use this form and answer the questions for each plant listed below based on your own personal experiences, and in as much detail as you are willing.
NOTE: Obviously, choosing the best and most comprehensive weed control program for a particular body of water can be very subjective and requires a level of experience literature can’t provide. This poll is just intended to provide the best biological and chemical tools available to battle each plant species. Thus, for now, there is no need to mention other techniques such as retreatment, combining biological and chemical, shading with fertilization or dyes, deepening shallow areas, nutrient reduction, etc. There is no need to indicate any state restrictions for biological control or chemical control agents. Applicators should be aware of this already. Also, refrain from listing specific chemical application rates or possible water quality/toxicity issues as this information is listed in the product label and should be left to the discretion of the applicator in each situation.
ANOTHER NOTE: You will be asked to provide the most effective chemical treatment for each plant; however, a different chemical treatment may be more practical or affordable in some situations. Provide that info in the “Additional Notes or Comments” section at the bottom. Also, if your control information for one plant is the same as another plant on the list, then you can just indicate that besides the plant’s name. If you have no experience controlling a particular plant, just leave blank.
