Product Label SDS
Navigate is an aquatic granular formulation of 2, 4-D. A
granular aquatic herbicide, which selectively controls some of the
most troublesome aquatic plants. These include water milfoil,
coontail, and spatterdock. Gradual release and systemic action
ensures complete kill of the entire plant.
Navigate is formulated on special heat treated attaclay granules
that resist rapid decomposition in water, sink quickly to lake or
pond bottoms and release the weed killing chemical in the critical
root zone area. This product is designed to selectively control the
weeds listed on the label. While certain weeds may be suppressed,
control may be incomplete. Reduced control may occur in lakes where
water replacement comes from bottom springs.
Initial effects occur in 7 to 10 days, indicated by brittle
stems and curling leaf tips. Full kill will occur in 3 to 5 weeks.
Once dead, weeds sink to the bottom and decompose.
The most comprehensive up to date peer review of all data
pertaining to 2,4-D was published by the Journal of American
College of Toxicology in 1992. As far as the scientific evidence is
concerned 2,4-D ...in aquatic situations under label
directions....is effective, it decomposes easily, it does not
accumulate in living tissue.

Navigate granular herbicide is very easy to apply using a scoop,
cup, or a hand spreader. Just simply scoop up some Navigate
granules and throw them directly onto the milfoil, water lilies, or
coontail. It is best to treat the vegetation early in the season
while it is still actively growing.
The key to proper applications is to estimate your square footage
of weeds and then make sure to get the right amount of Navigate
evenly spread throughout the area.
Floating and Emergent Weeds: Maximum of 21.0 pounds per
acre-foot. See label for complete directions and rates.
Submersed Weeds: Maximum of 56.8 pounds per acre-foot. See label
for complete directions and rates.
2ppm = 28.4 pounds per acre foot
4ppm = 56.8 pounds per acre foot

For best results, spread Navigate in the spring and early
summer, during the time weeds start to grow. If desired, this
timing can be checked by sampling the lake bottom in areas heavily
infested with weeds the year before. If treatments are delayed
until weeds form a dense mat or reach the surface, two treatments
may be necessary. Make the second treatment when weeds show signs
Heavy clay, mud, or silt build up may
reduce root absorption by effectively sealing the roots. Early
season application or more than one application may overcome this
problem. Water movement in the form of currents or bottom springs
may wash herbicide from the treatment site and reduce
Avoid churning the water in the treatment site for 72 hours
following application. This will help insure maximum herbicide is
available for absorption by the weeds.
Wait about 10 days
and then go back to that same area again and treat any remaining

local regulatory agency before applying herbicides and algaecides
