Chara (pronounced CARE-ah) is an advanced form of algae often mistaken for higher vascular plants. Common names include muskgrass or stonewort. Identified by a strong musky odor when crushed and a gritty feeling texture due to calcium deposits on the surface. When removed from water Chara will dry out within just a few hours of sunlight exposure appearing ashen to white once dry. Chara will not grow to the surface. Dense growths, attached but not rooted may cover entire bottom of shoreline areas or ponds.
Q. What are the best control options?
A. Algaecide Application:
Cutrine Plus Granular is our #1 recommendation. The active ingredient release of the granule at the bottom near the greatest algae mass is a big plus. Cutrine Plus liquid is also effective especially if algae mass is also near the surface. Copper sulfate is also effective but because it ships HazMat the additional shipping fees for small orders can be prohibitive. Larger orders of approximately 8 plus bags (400 lbs.) can be shipped economically.
Raking is not effective.
Q. When is the best time to treat?
A. Small areas can be hand raked. Chara is a heavy algae type.
Q. How do I actually apply the product(s)?
A. The Cutrine Plus granules can be spread by a small hand-held spreader or can be tossed by a hand scoop. A hand held pump up sprayer or Solo backpack sprayer can apply liquids such as Cutrine Plus liquid.
Q. How often do I need to treat Chara (Branched algae)?
A.If you catch it early one treatment can last the season. Two or more treatments may be required when Chara is mature.
Q. How long before I see results?
A. Generally within six to fifteen days depending upon water hardness and growth cycle. things will be cleared up.
