Description

Flumigard™ Herbicide is a professional-grade, water-soluble granular treatment engineered for rapid control of floating and submerged pond weeds including duckweed, watermeal, hydrilla, milfoil, elodea, and algae. Its active ingredient, 51% flumioxazin, acts at the cellular level to prevent regrowth and restore water clarity within 7–14 days. Designed for convenience, the granules dissolve quickly in water, making application simple and effective without complex mixing or spraying. Unlike many competitors, Flumigard allows swimming and fishing immediately after treatment, so your pond remains usable while weeds are eliminated. Ideal for residential ponds, aquaculture, or golf course water features, Flumigard delivers broad-spectrum, visible results safely and efficiently.
