Organic Weed Control - Concentrate

Mirimichi Green Organic Weed Control is a fast-acting, nonselective, organic herbicide that can be used for residential, commercial lawns, and non-crop uses. This is an excellent alternative to glyphosate for killing your entire lawn as part of a renovation project. This weed killer is non-selective. It will kill grass and weeds.

• Visible results in 15 minutes
• Delivers organic control or burn down of weeds / grass
• Leaves no harmful residues
• Readily biodegradable

It is a great natural alternative to traditional weed killer products. Mirimichi Green Weed Control is ideal for controlling weeds in gardens, greenhouses, walkways, farmsteads, and flower beds or spot treating around ornamental trees, bushes, flowers, and landscaping beds. Mirimichi Green Weed Control is registered for public uses such as municipalities, sports fields, and golf courses. The product is safe for people and pets when used as directed.

The formulation is available in an easy-mix concentrate and in a ready-to-use spray. It does not require a surfactant and will start showing results after just 15 minutes. The powerful organic formula acts on contact and is rainfast in two hours after drying. Because Mirimichi Green Weed Control is rapidly broken down in the soil, there is no chance for environmental buildup or runoff into waterways and it will not leach through the soil to harm desirable plants.

Because Mirimichi Organic Weed Killer is non-selective, its use should be limited to mulch beds, sidewalks and other areas where non-selective weed control is desired.

It will injure or kill plants it is sprayed on so we do not recommend using this product within your lawn.
