AQUATIC APPLICATIONS - WATER MILFOIL (MYRIOPHYLLUM SPICATUM) - AIR APPLICATION
Performance of product may be affected by local conditions, crop varieties, and application method. User should consult local Extension Service, Agricultural Experiment or University Weed Specialists, and state regulatory agencies for recommendations in his area.
Best results are obtained when product is applied to young succulent weeds that are actively growing. The lower recommended rates will be satisfactory on susceptible annual weeds. For perennial weeds and conditions such as the very dry areas of the western states where control is difficult, the higher recommended rates should be used.
When product is used for weed control in crops, the growth stage of the crop must be considered.
Some plants and weeds, especially woody varieties, are difficult to control and may require repeat applications.
Application rates should be 1 to 5 gallons of total spray by air or 5 to 25 gallons by ground equipment unless otherwise directed. In either case, use the same amount of 2,4-D recommended per acre. For crop uses, do not mix with oil, surfactants, or other adjuvants unless specifically recommended. To do so may reduce herbicide's selectivity and could result in crop damage.
Aerial applications should be used only when there is no danger of drift to susceptible crops. Many states have regulations concerning aerial application of 2,4-D formulations. Consult local regulatory authorities before making applications. This product contains dimethylamine salt of 2,4-D, one of the least volatile forms of 2,4-D.
Because coarse sprays are less likely to drift than fine, do not use equipment (such as hollow cone small orifice nozzles) or conditions (such as high pressure) that produce such sprays.
Product should not be allowed to come into contact with desirable, susceptible plants such as beans, cotton, fruit trees, grapes, legumes, ornamentals, peas, tomatoes, and other vegetables. Product should not be used in greenhouses. Excessive amounts of this product in the soil may temporarily inhibit seed germination and all plant growth.
Users should note that herbicide treatment of public water requires a permit from appropriate state agencies in most states. Your State Conservation Department or Game and Fish Commission will aid you in securing a permit in your state.
Spray equipment used to apply 2,4-D should not be used for any other purpose until thoroughly cleaned by a suitable chemical cleaner.
AQUATIC APPLICATIONS - WATER MILFOIL (MYRIOPHYLLUM SPICATUM)
Water Milfoil (Myriophyllum spicatum): For Eurasian Water Milfoil in programs conducted by the Tennessee Valley Authority in dams and reservoirs of the TVA system. 2,4-D Amine 4 will control Water Milfoil with surface, subsurface and air applications.
How to Use: To control Water Milfoil when less than 5 gallons of concentrate per acre is recommended, dilute the concentrate with water to apply a minimum of 5 gallons of spray mix per acre. Do not treat within 1/2 mile of potable water intakes. Shoreline areas should be treated by sub-surface injection applied by boat to avoid aerial drift. Do not apply when weather conditions favor drift from target area. Do not contaminate water by cleaning of equipment washwaters.
Open Water Areas: To reduce contamination and prevent undue exposure of fish and other aquatic organisms, do not treat water areas that are not infested with aquatic weeds.
Air Application: Use drift control spray equipment or thickening agents mixed into the spray solution. Apply 2-1/2 to 10 gallons per acre of 2,4-D Amine 4 through standard boom systems with a minimum of 5 gallons of spray mix per acre. For MICROFOIL drift control spray systems apply 2,4-D Amine 4 in 12 to 15 gallons spray mix per acre.
When to Apply: For best results, apply in spring or early summer when Milfoil starts to grow. This timing can be checked by sampling the lake bottom in areas heavily infested with weeds the year before.
