ENVIRONMENTAL HAZARDS
For terrestrial uses: This pesticide is toxic to fish and aquatic invertebrates and may contaminate water through runoff. This product has a potential
for runoff for several months or more after application. Poorly draining soils and soils with shallow water tables are more prone to produce runoff that
contains this product. Drift and runoff may be hazardous to aquatic organisms in water adjacent to treated areas.
Do not apply directly to water, to areas where surface water is present, or to intertidal areas below the mean high water mark. Do not contaminate
water when disposing of equipment washwater or rinsate.
For aquatic uses: This pesticide is toxic to fish and aquatic invertebrates. Waters treated with this product may be hazardous to aquatic organisms.
Treatment of aquatic weeds and algae can result in oxygen loss from decomposition of dead algae and weeds. This oxygen loss can cause fish and
invertebrate suffocation. To minimize this hazard, do not treat more than 1/2 of the water body to avoid depletion of oxygen due to decaying
vegetation. Wait at least 14 days between treatments. Begin treatment along the shore and proceed outwards in bands to allow fish to move into
untreated areas. Consult with the State or local agency with primary responsibility for regulating pesticides before applying to public waters, to
determine if a permit is required.
Certain water conditions including low pH (S6.5), low dissolved organic carbon (DOC) levels (3.0 mg/L or lower), and "soft" waters (i.e., alkalinity less
than 50 mg/L), increases the potential acute toxicity to non-target aquatic organisms.
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
PHYSICAL OR CHEMICAL HAZARDS
Do not use, pour, spill or store near heat or open flame.
CHEMIGATION PROHIBITION
Do not apply this product through any type of irrigation system.

SPRAY DRIFT MANAGEMENT
A variety of factors including weather conditions (e.g., wind direction, wind speed, temperature, relative humidity) and method of
application (e.g., ground, aerial, airblast, chemigation) can influence pesticide drift. The applicator must evaluate all factors and make
appropriate adjustments when applying this product.
Droplet Size
Apply only as a medium or coarser spray (ASAE standard 572) or a volume mean diameter of 300 microns or greater for spinning
atomizer nozzles.
Wind Speed
Do not apply at wind speeds greater than 15 mph. Only apply this product if the wind direction favors on-target deposition
(approximately 3 to 10 mph), and there are no sensitive areas within 250 feet downwind.
Temperature Inversions
If applying at wind speeds less than 3 mph, the applicator must determine if a) conditions of temperature inversion exist, or b) stable
atmospheric conditions exist at or below nozzle height. Do not make applications into areas of temperature inversions or stable
atmospheric conditions.
Other State and Local Requirements
Applicators must follow all state and local pesticide drift requirements regarding application of copper compounds. Where states have
more stringent regulations, they must be observed.
Equipment
All aerial and ground application equipment must be properly maintained and calibrated using appropriate carriers or surrogates.
Additional requirements for aerial applications:
- The boom length must not exceed 75% of the wingspan or 90% of the rotor blade diameter.
- Release spray at the lowest height consistent with efficacy and flight safety. Do not release spray at a height greater than 10 feet
above the crop canopy unless a greater height is required for aircraft safety.
- When applications are made with a crosswind, the swath must be displaced downwind. The applicator must compensate for this
displacement at the up and downwind edge of the application area by adjusting the path of the aircraft upwind.
Additional requirements for ground boom application:
Do not apply with a nozzle height greater than 4 feet above the crop canopy."
DIRECTIONS FOR USE
It is a violation of Federal law to use this product in a manner inconsistent with its labeling.
Do not apply this product in a way that will contact workers or other persons, either directly or through drift. Only protected handlers may be in the
area during application. For any requirements specific to your State or Tribe, consult the State or Tribal agency responsible for pesticide regulation.

Helena Copper-Z 4/4 can be used to control Algae in impounded waters, lakes, ponds and reservoirs, for algae and potomogeton pond weed control
in waters destined for use as drinking water or irrigation conveyance systems and for fungicidal control of specific diseases on crops.
DIRECTIONS FOR USE
This liquid copper sulfate product is easy and ready to use to control algae in slow moving or quiescent bodies of water including: golf course,
ornamental, fish, irrigation and fire ponds; fresh water lakes and fish hatcheries; water destined for drinking water and non-potable water reservoirs
and associated waters (river, streams, bays and coves); and crop and noncrop irrigation conveyance systems (canals, laterals and ditches). Waters
treated with Copper-Z 4/4 may be used for swimming, fishing, drinking (after further treatment), livestock watering or irrigating turf, ornamental plants
or crops.
Copper-Z 4/4 effectively controls many species of both filamentous (mat forming green algae) and planktonic (single cell blue-green) algae. The
rate of copper sulfate and control are affected by algae species, water hardness, water temperature, amount of algae present, as well as whether
water is clear, turbid, flowing, or static. Preferably water should be clear and above 60 DEGREES F, with treatment made in the late morning on a
sunny day. Static water usually requires less copper sulfate than flowing water. The harder the water, the higher the required rate of copper sulfate.
When mats of filamentous algae are floating, the surface of these mats should be sprayed. Algae will absorb the copper sulfate within hours after
treatment, and death should be evident within 3 to 5 days. If there is some doubt about the concentration to apply, begin with a lower rate and
increase the rate until the algae are killed. (A few algae species are resistant to copper sulfate treatment and may not be killed). Repeat treatments
may be needed to keep algae under control to the desired levels.
Treatment of algae can result in oxygen loss form the water caused by the decay of dead algae. This loss can cause fish suffocation. To minimize
this hazard, treat 1/3 to 1/2 of the water area in a single operation and wait 14 days between treatments. Begin treatments along the shore and
proceed outwards in bands to allow fish to move into untreated water. Trout and other species of fish may be killed at application rates
recommended on this label, especially in soft and acid waters.
1. For Algae Control in Reservoirs, Lakes, Ponds, Impounded Waters:
When to apply: Early treatment is essential for most satisfactory algae control at the lowest rate levels. Early growth is usually confined to
shallower shore areas. Begin treatment when not over 5 to 10% of the water surface area is covered with algae growths which is usually
nearest the shoreline. Delaying treatment until heavy algae growths are present usually requires a higher rate and may result in fish
distress or death since rapid decomposition of heavy growths greatly reduces the oxygen content of the water. Several repeat treatments
are necessary to control algae each season.
How to apply Copper-Z 4/4: Dilute the recommended amount of this product in sufficient water to thoroughly and uniformly spray the water
surface including any floating algae mats.
Rates to Control Algae: First, accurately determine the surface acres of water to be treated at one time and multiply this by the average
depth in feet of this water area to determine the acre feet of water to be treated. [One acre foot = one surface acre (43,560 sq. ft.) x one
foot depth.]
Each acre foot of water contains 326,000 gallons, or 2,720,000 pounds of water. Since recommended concentrations are normally given in parts per
million (ppm), it will first be necessary to convert the value in parts per million to a decimal equivalent. For example, 2 ppm is the same as 0.000002
when used in this calculation. Therefore, to calculate the amount of Copper Sulfate Pentahydrate to treat 1 acre-foot of water with 2 ppm Copper
Sulfate, the calculation would be as follows:
0.000002 x 2,720,000 = 5.44 Ibs. Copper Sulfate Pentahydrate.
To obtain the correct amount of Helena Copper-Z 4/4 divide 5.44 Ibs.
by 1.53 Ibs. which equals 3.5 gallons of Copper-Z 4/4. The rates of
Copper-Z 4/4 per acre foot of water to control specific algae species
are given later in the label.
Secondly, if the problem algae genera is known, use the table below and its equivalence to determine the approximate rate of this product needed to
control that genera. If the genera of either filamentous or planktonic algae is not known, apply 6.2 - 9.3 quarts of this product per acre foot of water,
using the lower rate in soft water and the higher rate to hard water. For control of bottom-attached algae Chara and Nietella use 9.3 -12.8 quarts
per acre foot of water to be treated. If control is not achieved or in very adverse waters, a higher rate may be needed. DO NOT EXCEED LABELED
RATES.

2. Algae Control in Rice Fields: Apply 6.3 to 7.0 gallons Copper-Z 4/4 liquid per acre foot of water to the water surface as a surface spray.
Application should be made when the algae has formed on the soil surface but prior to rising of the water surface.
3. Tadpole Shrimp Control in Rice Fields: Apply 3.1 to 6.3 gallons of Copper-Z 4/4 liquid per acre to the flooded field at any time the pest appears
between planting time and until the seedlings are rooted and have emerged through the water surface. The lower rate should be used when the
water depth and flow rate are minimal and higher rate should be used when the water depth and flow are at a maximum.
RESTRICTIONS AND LIMITATIONS
Fish Ponds and Fish Hatcheries (Aquaculture): Maximum treatment level is 0.4 ppm of metallic copper (2.8 gallons of Copper-Z 4/4 per acre foot of
water).

DRIP SYSTEM APPLICATION
FOR USE IN CANALS, DITCHES, LATERALS AND OTHER IRRIGATION CONVEYANCE SYSTEMS
• Copper-Z 4/4 should be applied as soon as algae or Hydrilla begins to interfere noticeably with normal delivery of water
(clogging of lateral headgates, suction screens, weed screens and siphon tubes). Delaying treatment could perpetuate the
problem causing massing and compacting of plants. Heavy infestations and low flow conditions increasing water flow rate
during application may be necessary.
• Prior to treatment it is important to accurately determine water flow rates. In the absence of weirs, orifices, or similar
devices which give accurate water flow measurements, volume of flow may be estimated by the following formula:
Average Width (feet) x Average Depth (feet) x Velocity* (feet/second) x 0.9 —
Cubic Feet per Second (C.F.S.)
"Velocity is the time it takes a floating object to travel a given distance. Dividing the distance traveled (feet) by the time
(seconds) will yield velocity (feet/second). This measurement should be repeated at least three times at the intended
application site and then averaged.
• After accurately determining the water flow rate in C. F. S. or gallons/minute, find the corresponding Copper-Z 4/4 drip
rate on the chart below.

• Calculate the amount of COPPER-Z 4/4 needed to maintain the drip rate for a period of 3 hours by multiplying Qts./Hr. x
3; ml/Min. x 180;orFI. Oz./Min. x 180. Dosage will maintain 1.0 ppm metallic copper concentration in the treated water
for the 3 hour period. Introduction of the chemical should be made in the channel at weirs or other turbulence-creating
structures to
promote the dispersion of chemical.
• Pour the required amount of COPPER-Z 4/4 into a drum or tank equipped with a brass needle valve and constructed to
maintain a constant drip rate. Use a stop watch and appropriate measuring container to set the desired drip rate. Readjust
accordingly if flow rate changes during the 3 hour treatment period.
• Distance of control obtained down the waterway will vary depending upon density of vegetation growth. Treatment
period may have to be extended up to 6 hours in areas where control may be difficult due to high flows or significant
growth. Periodic maintenance treatments may be required to maintain seasonal control.
• Wait 14 days before retreatment.
FOR FUNGICIDE USE
Use as directed below. Depending on the equipment used and the specific crop, the volume applied per acre will differ. For high volume sprays,
use from 25 to 100 gallons per acre (GPA). For concentrate ground sprays, apply form 20 to 50 GPA. For aerial spraying, 3 to 15 GPA are
commonly used.
