Hard Surfaces & Roof Moss

Professional Moss & Algae Control Herbicide


What is Moss Melt Concentrate?

Moss Melt is a high concentration, low dose contact herbicide for the control of moss & algae that has just received full EPA registration. Moss Melt contains d – limonene, or citrus oil extract, a powerful, natural degreasing agent that strips away the waxy cuticle from moss & algae, causing fast wilting (necrosis), dehydration and death. Moss Melt is a 70% concentration material; thus little bit goes a long way. One gallon of Moss Melt will treat 12,500 sq. ft. of regular moss and 8,333 sq. ft. of thick moss.

What is the application rate?

For general purpose broadcast applications, use product at a ratio of 1 part Moss Melt into 50 parts of water (2%) spray solution (2.56 ounces / gallon of water) For best performance thorough coverage of moss or algae is necessary. The volume required per 1000 sq. ft. will depend on density of moss. At least 3.5-4 gals per 1000 sq. ft. is recommended to insure adequate coverage.

Fast Acting

Moss Melt is fast acting, effects will be seen within one – three days. Treated moss will turn a light yellow to dark orange color.


Moss Melt has shown to be effective in university and independent trials, as well as, commercial use: killing moss more effectively than competitive herbicides.

No Unpleasant Odor

Unlike fatty acid products Moss Melt leaves a pleasant citrus odor during and shortly after applications.

Where can I use Moss Melt?

Moss Melt is labelled on surfaces such as Roofs, Driveways, Fences, Decks, Siding, Steps, Patios, and Other Outdoor Surfaces constructed of Composition Shingles, Wood, Asphalt, Concrete, Brick, Tile, Stone and Plastic Resins.

Worker & Environmental Safety

Moss Melt carries the lowest pesticide signal word of “Caution” reducing concerns about applicator exposure. It also meets the “NOP” organic guidelines and will soon be OMRI organic listed. It is non toxic and treated areas can be entered once product dries. Moss Melt is highly biodegradable and results in no ground water contamination or toxic residue.

Low Use Rate

Moss Melt covers significantly more area than competing products. It would require 75 pounds of zinc sulfate to treat the same area as one gallon of Moss Melt Concentrate.
