Per the product label for Hi-Yield 2, 4-D Selective Weed Killer: AQUATIC WEED CONTROL (Surface Application to Floating and Emergent Weeds) Boat Application: Use 1 gallon of this product in 25 gallons of water per acre. Uniform coverage is essential. Avoid submerging plants after treatment. Application should be made when leaves are fully developed above water line and plants are actively growing. Treatment of aquatic weeds can result in oxygen loss from decomposition of dead weeds. This loss can cause fish suffocation. Therefore, to minimize this hazard, treat 1/3 to 1/2 of the water area in a single operation and wait at least 21 days between treatments. Begin treat- ments along the shore and proceed outwards in bands to allow fish to move into untreated areas. The maximum rate per broadcast application is 4.7 gallons per surface acre, limited to applications is 2 per year. Do not make a broadcast application within 21 days of previous broadcast application. Spot treatments are permitted. Apply to emergent aquatic weeds in ponds, lakes, reservoirs, marshes, bayous, drainage ditches, non-irrigation canals, rivers, and streams that are quiescent or slow moving SPOT TREATMENT IN NON-CROP AREAS: To control broadleaf weeds in small areas with a hand sprayer, use 1 pint (4 fluid ounces) of this product in 3 gallons (3/4 gallon) of water and spray to thoroughly wet all foliage.
