Terry from Suffolk writes
Per the product label of Roundup Custom Aquatic Terrestial Herbicide: For areas outside of FL, you would apply 2-3 quarts per acre (per in 100 gallons) as a broadcast spray or apply a 0.75% (1 oz per gallon) solution with hand-held equipment for partial control. For best results, treat during late summer or fall months when plants are actively growing and in full bloom. Due to the dense nature of the vegetation, which may prevent good spray coverage and uneven stages of growth, repeat treatments may be nesessary to maintain control. Visual control symptoms will be slow to develop.
