Abstract: Aquatic herbicidal formulations generally including at least one active ingredient and at least one functional additive that promotes nutrient sequestration. For example, in one embodiment the at least one functional additive includes a nutrient-binding ingredient that binds certain nutrients (such as nitrogen, phosphorous, nitrogenous compounds, and/or phosphoric compounds) within the target plant, from an environment surrounding or proximate the target plant, and/or as those nutrients are released after the application of the active ingredient.

Abstract: Described are preferred solid herbicidal formulations that include one or more herbicides in combination with a solid carrier, as well as methods of manufacture and use thereof. Solid herbicidal formulations are designed to deliver a moderated release of the incorporated load of herbicidal agent(s), for example to enhance uptake by target plants and/or the ability to spatially control a plant population within a body of water that exhibits flow.
