General Information


When applying this product follow all applicable use directions, precautions and limitations.

For Aquatic and Wetland Sites: Use this product for control of emersed, submersed and floating aquatic weeds in the following aquatic sites: ponds; lakes; reservoirs; marshes; wetlands; impounded rivers, streams and other bodies of water that are quiescent; non-irrigation canals, seasonal irrigation waters and ditches which have little or no continuous outflow.


Water chestnut: Not for use in California and New York.

Parrotfeather, Water chestnut: Retreatment may be needed to achieve desired level of control.


State of New York specific restriction: Note to all pesticide applicators: Before application under any project program, notification of an approval by the NYS Department of Environmental Conservation is required, either by an aquatic permit issued pursuant to ECL Section 15.0313(4) or issuance of purchase permits for use.

Irrigation: Water treated with this product may not be used for irrigation purposes for 120 days after application or until triclopyr residue levels are determined by laboratory analysis, or other appropriate means of analysis, to be 1.0 ppb or less. The label describes both required and recommended uses of a chemical analysis for the active ingredients triclopyr. Applied Biochemists recommends the use of an Enzyme-Linked Immunoassay (ELISA) test for the determination of the active ingredient concentration in water. Contact Applied Biochemists for the incorporation of this analysis in your treatment program. Other proven chemical analysis for the active ingredient may also be used. The ELISA analysis is referenced in the label as the preferred method for rapid determination of the concentration of the active ingredient in the water. Seasonal Irrigation Waters: This product may be applied during the off season to surface waters that are used for irrigation on a seasonal basis, provided that there is a minimum of 120 days between product application and the first use of treated water for irrigation purposes or until triclopyr residue levels are determined by laboratory analysis, or other appropriate means of analysis, to be 1.0 ppb or less. Irrigation Canals/Ditches: DO NOT apply this product to irrigation canals/ditches unless the 120 day restriction on irrigation water usage can be observed or triclopyr residue levels are determined by laboratory analysis, or other appropriate means of analysis, or other appropriate means of analysis, to be 1.0 ppb less. There is no restriction on use of treated water to irrigate established grasses. DO NOT apply this product directly to, or otherwise permit it to come into direct contact with grapes, tobacco, vegetable crops, flowers, or other desirable broadleaf plants, and do not permit product dust to drift into them. DO NOT apply to salt water bays or estuaries. DO NOT apply directly to un-impounded rivers or streams. DO NOT apply on ditches or canals currently being used to transport irrigation water or that will be used for irrigation within 120 days following treatment or until triclopyr residue levels are determined to be 1.0 ppb or less. DO NOT apply where runoff water may flow onto agricultural land as injury to crops may result. Grazing and Haying Restrictions: Except for lactating dairy animals, there are no grazing restrictions following application of this product. Grazing Lactating Dairy Animals: DO NOT allow lactating dairy animals to graze treated areas until the next growing season following application of this product. DO NOT harvest hay for 14 days after application. Grazed areas of non-cropland and forestry sites may be spot treated if they comprise no more than 10% of the total grazable area. Slaughter Restrictions: During the season of application, withdraw livestock from grazing treated grass at least 3 days before slaughter.

Limitations, Restrictions, and Exceptions

Wetland Sites: Wetlands include flood plains, deltas, marshes, swamps, bogs and transitional areas between upland and lowland sites. Wetlands may occur within forests, wildlife habitat restoration and management areas and similar sites as well as areas adjacent to or surrounding domestic water supply reservoirs, lakes and ponds.

For control of emersed, floating or submersed aquatic weeds in wetland sites, follow use directions and application methods associated with the Floating and Emersed or Submersed sections on the label.

Use Precautions: Minimize unintentional application to open water when treating target vegetation in wetland sites. Note: Consult local public water control authorities before applying this product in and around public water. Permits may be required to treat such areas.


Surface Applications: Use a mechanical spreader such as a fertilizer spreader or mechanical seeder or similar equipment capable of uniformly applying this product. Before spreading any product, carefully calibrate the application equipment. When using boats and power equipment, you must determine the proper combination of (1) boat speed, (2) rate of delivery from the spreader, and (3) width of swath covered by the product. Use the following formula to calibrate the spreader’s delivery in pounds of this product per minute. Refer in the label for formula.

Aerial Application (Helicopter Only): Ensure uniform application. All equipment should be properly calibrated using blanks with similar physical characteristics to this product. To avoid streaked, uneven or overlapped application, use an appropriate tracking device (e.g. GPS). Refer to the Aerial Drift Reduction Advisory section of the label for additional precautions and instructions for aerial application.
