Cutrine® Plus Algaecide and Herbicide

This product is a liquid copper-based formulation containing ethanolamine chelating agents to prevent the precipitation of copper with carbonates and bcarbonates in the water. 

This product effectively controls a broad range of algae including: Planktonic (suspended) forms such as the Cyanobacteria (Microcystis, Anabaena & Aphanizomenon), Green algae (Raphidocelis & Cosmarium) Golden algae (Prymnesium parvum) and diatoms (Navicula & Fragilaria).  Filamentous (mat-forming) forms such as the Green Alage (Spirogyra, Cladophora, Ulothriz & Rhizoclonium) and Benthic (bottom-growing) forms such as Chara and Nitella. 

Water 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.

Treatments with this product should be started when visible, actively growing algae and susceptible plants appear in spring, preferably before significant surface accumulations occur.  Aeration and/or fountain systems, where available, should be in operation at the time of treatment.

Waters treated with this product may ne hazardous to aquatic organisms.  Treatment of aquatic weeds and algae can result in oxygen loss from decoposition of dead algae and weeds.  This oxygen loss can cause fish and invertebrate suffocation .  To minimize hazard, do not treat more than 1/2 of the water body to avoid depletion of oxygen due to decaying vegetation.  Wait at least 10-14 days between treatments.  Begin treatment along the shore and proceed outwards in bands to allow fish to move into untreated areas.  In regions where ponds feeze in winter, treatment should be done 6 to 8 weeks before expected freeze time to prevent masses of decaying algeae under an ice cover.

Certain water conditions including low pH (< 6.5) low dissolved organic carbon (DOC) levels (3.0 mg/L or lower), and "soft" waters (i.e., alkalinity less than 50mg/L), increases the potential acute toxicity to non-target aquatic organism.  Potable water sources treated with copper products may be used as drinking water only after proper additional potable water treatments.  Trout and other species of fish may be killed at application rates recommened on this label, especially in soft or acidic waters as described above.

Do not use in waters containing Koi and hybrid goldfish.  Not intended for use in small volume, garden pond systems.

Calculate water volume (acre-ft) from directions and choose Application rate from charts on label for best results.   Dilute product 9:1 or 12oz. of product concentrate per gallon of water for even coverage over treatment area.
