Finalsan Organic Herbicidal Soap

Control or suppress common weeds!

Finalsan Herbicidal Soap is an OMRI-listed, non-selective weed killer. The active ingredient is ammoniated soap of fatty acids. It works by allowing free fatty acids to accumulate in the plant cells. These acids cause intracellular damage, leading to cell collapse. It penetrates the waxy cuticle of plants, causing them to dehydrate and die. This is a 2-1/2-gallon container. Finalsan Herbicidal Soap controls or suppresses many common annual, biennial, and perennial weeds. Works well on grasses, chickweed, dandelions, groundsel, mustards, plantains, moss, and algae. Use it around landscaping areas, fruit trees, buildings, fences, driveways, or gravel. Finalsan kills plants on contact. It will not reach underground portions of plants and will not cause harm to the bark of mature wood plants. For established weeds, mix one part Finalsan with five parts water. For other weeds, mix one part Finalsan with nine parts water. Apply at a rate of 2 to 4 gallons per 1,000 square feet.
