Alligare Argos Herbicide is an excellent defense against a wide range of algae. Contains copper ethanolamine which is highly effective in preventing the precipitation of copper in water. It targets and controls planktonic, filamentous, and benthic types of algae. Alligare Argos Algaecide and Herbicide is specially formulated with a liquid copper-based formula, making it effective even in a wide range of water quality conditions. Controls algae such as golden algae, green algae, Cladophora, Cyanobacteria, Chara, Nitella, Rhizoclonium, and Spirogyra. It is proven to be long-lasting with 24 to 48 hours of control of planktonic algae and 3 to 4 days control of filamentous algae. May be used in ponds, lakes, fish hatcheries, drainage ditches, potable water reservoirs, and irrigation canals. It is a contact mode of action type of herbicide plus, it is also effective on Hydrilla especially when used with Diquat Herbicide. Available in a one gallon container jug.

It is a violation of Federal law to use this product in a manner inconsistent with its labeling. Read the entire label and use strictly in accordance with precautionary statements and directions.
For applications in waters destined for use as drinking water, those waters must receive additional and separate potable water treatment. Do not apply more than 1.0 ppm as metallic copper in these waters.
Do not apply this product in a way that will contact workers or persons, either directly or through drift. Only protected handlers may be in the area during application. For requirements specific to your State or Tribe, consult the State or Tribal agency responsible for pesticide regulation.
Do not enter or allow others to enter until the application of the product has been completed.
In Potable Water Reservoirs, Lakes, Industrial Ponds & Wastewater or other monitored water systems, initial treatment with this product must be considered at the onset of nuisance bloom conditions as evidenced by initial taste and odor complaints; high cell counts or chlorophyll a concentrations; high MIB or geosmin concentrations; visible surface scum formations; low Secchi disk readings; significant daily fluctuations in dissolved oxygen; and/ or sudden increases in pH. Monitoring of several of these parameters on a regular basis will assist in optimizing the timing of treatments and reducing the amounts of this product needed for seasonal control. Identification of primary nuisance species or genera may also be helpful in determining and refining dosage rates.
In Ponds (Farm, Fire, Fish, Golf Course, Irrigation, Ornamental, Storm Water Retention, Swimming), Small Lakes, Fish Hatcheries, Aquaculture Facilities, treatment with this product should be started when visible, actively growing algae and susceptible plants appear in the spring, preferably before significant surface accumulations occur. Aeration and/or fountain system, where available, should be in operation at the time of treatment.
SLOW-FLOWING OR QUIESCENT WATER BODIES ALGAECIDE APPLICATION
For effective control, proper chemical concentration should be maintained for a minimum of three hours contact time. The application rates in the chart are based on static or minimal flow situations. Where significant dilution or loss of water from unregulated inflows or outflows occur (raceways) within a three hour period, the chemical may have to be metered in.
Identify the form of algae growth present as one of the following types: Planktonic (suspended), Filamentous (mat-forming), or Benthic (Chara/Nitella) and estimate the density of growth (Low, Medium, High).
Determine gallons of product needed per Acre-foot corresponding to the desired PPM concentration determined in step #1.
Determine acre-feet within the intended treatment area (area of infestation) by measuring length, width plus averaging several depth readings within the treatment area.
. Multiply Acre-Feet calculated in Step #3 times the gallons of Argos determined in Step #2 to determine the number of gallons of Argos required for the intended treatment area.
Before applying, dilute the required amount of Argos with enough water to ensure even distribution with the type of equipment being used. Typical dilution range is 9:1 when using a backpack-type sprayer or up to 50:1 when using water pump equipment or large tank sprayers.
Break up floating algae mats manually before spraying or with force of power sprayer if one is used. Use hand or power sprayer adjusted to rain-sized droplets to cover the area evenly taking water depth into consideration. If using underwater injection systems such as drop hoses or booms with weighted drop hoses, ensure boat pattern is uniform throughout the treatment area. Spray shoreline areas first to avoid trapping fish.
Clean spray equipment by flushing with clean water after treatment and follow STORAGE AND DISPOSAL instructions on the label for empty or remaining partial containers.
Under conditions of heavy infestation, treat only 1/3 to ½ of the water body at a time to avoid fish suffocation caused by oxygen depletion from decaying algae. (See additional Environmental Hazards).
HERBICIDE APPLICATION (For Hydrilla Control)
Control of Hydrilla verticillata can be obtained from copper concentrations of 0.4 to 1.0 ppm resulting from Argos treatment.
ARGOS: HARVESTER OR ALLIGARE DIQUAT HERBICIDE TANK MIX
On waters where enforcement of use restrictions for domestic uses are acceptable, the following mixture can be used as an alternative Hydrilla control method.
Tank mix 3 gallons of Argos with 2 gallons of Harvester or Alligare Diquat Herbicide. Apply mixture at the rate of 5 gallons per surface acre. Dilute with at least 9 parts water and apply as a surface spray or underwater injection. Observe all cautions and restrictions on the labels of both products used in this mixture.
