Aquatic Herbicides

Aquatic herbicides are chemicals specifically formulated for use in water to kill or control aquatic plants. Aquatic herbicides are sprayed directly onto floating or emergent aquatic plants or are applied to the water in either a liquid or pellet form. Aquatic Biologists, Inc. carries only EPA registered herbicides. On average, each of the products we carry has gone through 10 years of research to determine its toxicity level to humans, fish, wildlife, and the environment before being approved by the EPA. Unsure what to use? See our Weed Id Guide, Do-It-Yourself form or call us at 800-442-6648.

There are three different categories of aquatic herbicides; systemic, contact and selective. Systemic herbicides are capable of killing the entire plant. Contact herbicides cause the parts of the plant in contact with the herbicide to die back, leaving the roots alive and able to regrow. Non-selective, broad spectrum herbicides will generally affect all plants that they come in contact with. Selective herbicides will affect only some plants (often dicots - broad leafed plants like Eurasian watermilfoil (Myriophyllum spicatum) will be affected by selective herbicides whereas monocots like Brazilian elodea (Egeria densa) may not be affected). Most aquatic plants are monocots.
