Coptrol 20L

Coptrol commercial grade aquatic algaecide is safe and easy to use, APVMA approved and does not harm fish, livestock, plants, pastures or turf irrigated with water treated with Coptrol when used in accordance with label instructions.

Coptrol is a next generation algaecide, it will clear up existing algae, including toxic blue green algae. Coptrol offers a new approach to the control of an algal bloom (free floating or filamentous) in potable water supplies, animal drinking troughs, aquaculture, farm dams/ponds, flood irrigation bays, fountains, gardens, golf courses, hydroponics, irrigation channels, lakes, mining, microspray & drip irrigation, nurseries, ornamental fish ponds, poultry shedding, power stations, reservoirs, rice crops, sewage treatment, turf farms, waste water, water cooling towers, waterways, irrigation canals & other aquatic environments.

Coptrol can be used wherever algae pose a risk, problem or cause a nuisance. Coptrol is approved for use in potable water supplies (water supplies & tanks suitable for drinking) by the APVMA (Australian Pesticides& Veterinary Medicines Authority - reg no. 31030) to treat algae. Coptrol can be used in water supplies used for cattle & livestock watering. Coptrol will not harm livestock, birds, fish or domestic pets when used in accordance with the label directions. Coptrol can be used in water supplies used for irrigation. It will not harm flood irrigated rice fields, crops, hydroponic plants, turf, pastures or plants. There is no withholding period after a Coptrol application when used as directed. Coptrol is a non-corrosive viscous liquid that will not corrode metal pumps, fountains or irrigation equipment.

The volume of the water body should be calculated before treating with Coptrol. Do this by measuring the surface area & multiplying it by the average depth down to 1 meter (you can ignore depths below 1 meter).

Application Rates:

TheCoptrol application rate depends on the degree of algae infestation, the kinds of algae present & the depth of water to be treated.

For Tanks & Troughs: 
Apply 2 to 5 mL Coptrol per 1,000 litres of water to be treated.

For Dams, Ponds and Water Impoundments, including potable water storages: 
Apply 4.2 to 8.4 litres of Coptrol per 1,000 square meters of water surface area at an average water depth of 1 meter or greater, or 5 to 10L of Coptrol per 1 mega-litre of water.

How to Apply: 
Simply dilute the measured amount of Coptrol 1 part product to 10 or 20 parts water. Once diluted it can be applied from horticulture sprayers, knapsack sprayer or even from a bucket, apply evenly over the water’s surface.

For Best Results:
Apply Coptrol in bright sunlight on a calm, wind-free day evenly to the water’s surface. Ensure the water temperature is not below 16 degrees Celsius. In ponds containing fish, ensure the carbonate hardness of the water is higher than 50ppm. Treat the shoreline first to avoid trapping fish in the shallows and only treat 1/3 of the area at a time to avoid oxygen depletion. Allow 10-15 days for oxygen levels to recover before continuing treatment.

How often do I need to use it? Generally one application is enough. However, if the algae infestation is severe, re-treat after 10-14 days as necessary.

Always read the label directions & use as directed by the label.

Your Guide to Identifying & Controlling Aquatic Algae How to Identify Algae - there are two main types

1. Macro (or Filamentous Algae) Filamentous algae is green in appearance and sometimes brownish in colour if exposed to strong sunlight. It appears floating on the waters surface, amongst submerged rocks or in the shallows of dam and lake edges. It is stringy and looks like floating scum on the water surface. It is an indication of high nutrient loads in the water body. If left untreated, it can:

• Block irrigation pumps
• Cause a strong odour and distinct rotten egg smell
• Detract from the visual look of the water body
• Turn into an algae bloom and take over the water body

2. Micro (or Blue Green Algae) Micro algae can contain toxins such as in Blue Green Algae. Micro algae looks like a green oil slick or paint on the waters surface and tends to congregate in downwind edges of dams and lakes. This form of algae can be toxic to humans, domestic or native animals and birds. It is of most concern when people are in contact with water contaminated with toxic Blue Green Algae, if it is used for irrigation and staff are handling the water it can pose an OH&S risk. If the public has access to the water, it can be a duty of care risk.
