In shallow, porous soils, extra care must be taken with all herbicides to avoid root absorption by non-target plants. Aquatic herbicides are placed directly in water. As long as the herbicide is applied using label instructions, it is not toxic to any of the aquatic life in the pond. Volatile compounds such as ester formulations may cause non-target damage due to vapor drift when applied on very hot days. 1/8 acre with 3' average depth would require 12 Ounces (4 Ounces x 3)Mix the amount of Propeller and Treatment Booster Plus (if using) with water in a tank sprayer according to label instructions.

For example, large scale hydrilla (Hydrilla verticillata) control is mostly conducted in winter and early spring when hydrilla is actively growing but most native plants are dormant. Labeled rates of the potassium salt formulation of endothall (3-5 parts per million) are toxic to the beneficial native strap-leaf saggitaria (Sagittaria kurziana) that grows with hydrilla in Wakulla Springs.
