Item Information

Cutrine Plus Algaecide and Herbicide effectively controls a broad range of algae, specifically surface filamentous and planktonic algae including: Cyanobacteria, Green algae, Golden algae and diatoms, Filamentous Green Algae and Chara and Nitella.

Strong formulation provides fast results on most types of algae. for tough-to-kill algae, or algae mixed with aquatic plants, results are often improved when Cutrine Plus Algaecide is tank-mixed with Weedtrine D Aquatic Herbicide.

  • Powerful algae control
  • Visible reduction in algae growth 1 - 2 days after application
  • Double chelated formula prevents the precipitation of copper with carbonates and bicarbonates in the water
  • Works in 'hard' water

Rated 5 out of 5 by from excellent algaecide! I had red algae that took over my quarry where we swim and fish, in 1994. It looked like somebody dumped chemicals in the spring water. I bought Cutrine Plus when it was sold as liquid, diluted it in a small garbage can, then took a gallon juicer and dispersed around the one side of the quarry. The water was so clear 2 days later that everybody couldn't get over how effective it was. The day I took it and dispensed it, a gallon of dilute Cutrine Plus on the heavy red algae had an immediate effect on the algae. As I poured over the algae, it died immediately in front of our eyes. Every year since, and we don't have the red algae anymore, I have people buying Cutrine Plus on their own for here. I just had a man come up today with a new bunch, but granules. Everybody loves it, and it's safe to drink.

will it kill duck weed?

Asked by: Patches750
This product will not kill duckweed. Do not treat more than half of the surface area of the pond at once. The manufacturer advises to wait 2 weeks to treat other areas. If you have fish present in the pond, Cutrine Plus is toxic to Koi, Goldfish, Carp and Trout.

How much would I need for a 1.2 acre pond tha is 9-10 ft. max depth?

Asked by: dthomaso
1.2 acres x average depth 5ft= 6 acre-foot of water. Maximum dose of 3 gallons per acre-foot= 18 gallons Max. However, we would never recommend a maximum dose. It all depends on the algae. With no other details, start at a half rate and treat only 1/3 of the pond, wait 7-10 days and treat the next section.

I have a small 1/2 acre pond. Its shallow on one end. We have algae or what we call moss. Do you need a surfactant added? If you mix Cutrine Plus @ 50:1 in a spray will it take care of this?

Asked by: Brad 3838
For filamentous algae we recommend diluting 14 oz. of Cutrine Plus with every one gallon of water. No surfactant is needed but do spray directly onto the mats of algae. Also make sure you only treat 1/3 to 1/2 half of the pond at one time and wait 14 days between treatments. This will protect the aquatic life in the pond, also do not use if your pond contains Koi, Goldfish, Grass carp and Trout.

We have lowered our lake 6 feet for removal of trees from our dam. The bream beds are now exposed so that we can rake the dried algae from the beds. Alter raking the algae from the gravel beds, would spraying Cutrine Plus help in keeping the algae away?

Asked by: Larry84
We do not recommend using Applied Biochemists® Cutrine Plus when there is no water present in the area where you want to control the algae. However, you can contact Applied Biochemists for suggestions on what may work best for you. They are available every day 8:30 am - 8:00 pm EST at 800-558-5106.

Will it harm natural deposited creek fish, spot, minnows, brem in a farm pond, approx. 75000 gal.

Asked by: Pond mudder
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 hazard, do not treat more than ½ of the water body to avoid depletion of oxygen due to decaying vegetation. Wait at least 10 to 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 freeze in winter, treatment should be done 6 to 8 weeks before expected freeze time to prevent masses of decaying algae under an ice cover. 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. This pesticide is toxic to some 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. Do not contaminate water when disposing of equipment wash-waters or rinsate. 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 50 mg/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 recommended on the label, especially in soft or acidic waters as described above. Do not contaminate water when disposing of equipment washwaters or rinsate.
