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.
Claims14
An aquatic herbicidal formulation comprising:
- at least one active ingredient having herbicidal activity, the at least one active ingredient being present in an amount sufficient to cause death in a target plant when the aquatic herbicidal formulation is applied to the target plant, the at least one active ingredient including endothall;
- and
- at least one non-herbicidal functional additive, the at least one non-herbicidal functional additive including elemental lanthanum, the at least one non-herbicidal functional additive being present in an amount sufficient to bind to at least one of nitrogen and phosphorus that is released from the target plant when the aquatic herbicidal formulation is applied to the target plant.
An herbicidal formulation comprising:
- an active ingredient, the active ingredient being present in an amount sufficient to cause herbicidal activity against vascular aquatic plants, the active ingredient including endothall present in an amount of between approximately 20% and approximately 55%;
- and
- at least one non-herbicidal functional additive, the at least one non-herbicidal functional additive including:
- at least one nutrient-binding ingredient, the at least one nutrient-binding ingredient including elemental lanthanum present in an amount of between approximately 25% and approximately 55% and being a sufficient amount to bind at least one of nitrogen and phosphorus released from tissue of a vascular aquatic plant;
- and
- at least one adjuvant.
An aquatic herbicidal formulation comprising:
- at least one active ingredient, the at least one active ingredient being present in an amount sufficient to cause death of at least one target aquatic plant when the aquatic herbicidal formulation is applied to the at least one target aquatic plant, the at least one active ingredient including endothall and being present in an amount of approximately 40% of the aquatic herbicidal formulation;
- and
- at least one non-herbicidal functional additive, the at least one non-herbicidal functional additive being configured to bind free reactive phosphorus released from the at least one target aquatic plant as a result of an application of the aquatic herbicidal formulation to the at least one target aquatic plant, the at least one non-herbicidal functional additive including lanthanum chloride, the at least one non-herbicidal functional additive being present in an amount of approximately 29% of the aquatic herbicidal formulation that is sufficient to bind at least 10% of the free reactive phosphorus released from the at least one target aquatic plant.
