Cutrine Ultra - 2.5 GAL JUG

Product Label Download SDS

Cutrine-Plus Granular is a double-chelated copper solution effective against a wide variety of algal species. Due to its double-chelate it stays in the water column longer, and in combination with its greater amount of activity in the plant can be much more effective. Cutrine-Plus Granular is a clay based 3.7% absorbed copper in a chelated liquid form. Best for bottom growing algae such as Chara and Nitella.

Cutrine-Plus Granular Algaecide is effective in controlling a broad range of benthic (bottom-growing) algae including: Chara, Nitella and filamentous forms. Cutrine-Plus Granular Algaecide is also effective in controlling the rooted aquatic plant, Hydrilla verticillata. The ethanolamines in Cutrine-Plus Granular Algaecide prevent the precipitation of copper with carbonates and bicarbonates in the water.

Waters treated with this product may be used for swimming, fishing, further potable water treatment, livestock watering or irrigating turf, ornamental plants or crops after treatment.

Application

Surface Spray/Injection Slow-flowing or Quiescent water bodies - Algaecide Application For effective control, maintain proper chemical concentration 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, chemical may have tobe metered in (see FLOWING WATER Directions).
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).
Use Table 1 on label - Copper Concentration to select the desired PPM (Parts per Million) Copper needed, based upon the algal form and density.
Before applying, dilute the required amount of this product with enough water to ensure even distribution with the type of equipment being used. Typical dilution range is 9:1 when using handtype 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 area evenly taking water depth into consideration. If using underwater injection systems such as drop hoses or injection booms, ensure boat pattern is uniform throughout treatment area. Treat shoreline areas first to avoid trapping fish.

See Label for complete application instructions.

Restrictions

• Calm and sunny conditions when water temperature is at least 60ºF will usually expedite control results.
• Treat when growth first begins to appear or create a nuisance, if possible.
• Apply in a manner that will ensure even distribution of the chemical within the treatment area. Effective control of algae requires direct contact with all cells throughout the water column, since these plants do not have vascular systems to transport active ingredient from cell to cell.
• Visible reduction of algae is commonly observed in 24 to 48 hours following application, with full effects of treatments sometimes taking 7 – 10 days depending upon algae forms, weather, degree of infestation and water temperatures.
• Re-treat areas if re-growth or new growth begins to appear and seasonal control is desired. Identify new growth to recheck required copper concentrations that may be needed for control.
• Under conditions of heavy infestation, treat only 1/4 to 1/2 of the water body at a time to avoid fish suffocation caused by oxygen depletion from decaying algae. (See ENVIRONMENTAL HAZARDS).
