How to Apply:
Nautique Aquatic Herbicide provides effective control of hydrilla, egeria, southern naiad, horned pondweed, and widgeon grass in lakes, rivers, ponds, reservoirs, potable water sources, crop and non-crop irrigation systems (ditches, canals and laterals), fish, golf course, ornamental, swimming and fire ponds, and aquaculture including fish and shrimp. This product rapidly penetrates into the plant tissues. Proper application of this contact product is, therefore, important.
Nautique can be applied directly to actively growing plants as a surface spray or subsurface by holding the spray nozzle under water. For surface or subsurface application, this product may be applied diluted or undiluted, whichever is most suitable to insure uniform coverage of the area to be treated. The activity of this product may be reduced if there is insufficient penetration of light into the water or if plants are covered with silt, scale or algae.Aquatic plants will usually drop below the surface within 4-7 days after treatment. The complete results of treatment will be observed in 3-4 weeks in most cases. In heavily infested areas a second application may be necessary after 10-12 weeks. Repeating application of this product too soon after initial application may have no effect.
Use the lower rates for treating shallow water and the higher rates for treating deeper water and heavier infestation. Surface applications may be made from shore into shallow water along the shoreline. Nautique may be applied directly or tank mixed with water. For subsurface plants, applications should be made below the water surface by holding the spray nozzle below the surface of the water.
