Navigate® Herbicide – Aquatic Weed Killer for Ponds & Lakes

Navigate® Granular Aquatic Herbicide is a powerful 2,4-D based selective herbicide designed to control submerged and floating broadleaf weeds in ponds and lakes.

Formulated on heat-treated attaclay granules, Navigate sinks quickly to the bottom, releasing the active ingredient directly into the root zone for maximum effectiveness. It is especially effective against Eurasian Watermilfoil and other invasive aquatic weeds.

• Watermilfoil (including Eurasian Watermilfoil)
• Water Stargrass
• Bladderwort
• White & Yellow Water Lily (Spatterdock)
• Water Shield
• Water Chestnut
• Coontail*

*Repeat treatments may be necessary for resistant species.

• Apply evenly using a broadcast spreader.
• Typical rate: 5–7.5 lbs per 2,000 sq ft.
• Rates vary from 100–200 lbs per acre depending on target weed.
• 50 lb bag treats up to approximately 20,000 sq ft.

Initial results appear within 7–10 days. Full control typically occurs within 3–5 weeks as weeds die and decompose.

For heavy infestations, apply in lanes with untreated buffer strips (50–100 ft wide) to prevent oxygen depletion. Treat buffer areas after initial treated zones have decomposed.

Best results occur when applied in spring and early summer while weeds are actively growing.

Late season applications are possible but may require repeat treatments and results may not be fully visible until the following season.

Water pH below 8 generally yields best performance.

As treated weeds decompose, they consume oxygen. When weed density is heavy, treat in sections to maintain proper dissolved oxygen levels for fish safety.

For enhanced breakdown of dead vegetation, beneficial bacteria such as Muck Remover may be applied after treatment.
