Rating is 3.5 out of five stars based on 2 reviews
SKU: AVW1galConc

Avenger Organic and Natural Weed Killer is a non-selective, post-emergence herbicide that quickly and effectively kills weeds, grasses and broadleaves without causing harm to the environment.

The active ingredient d-limonene (citrus oil) naturally strips away the waxy plant cuticle, causing it to dehydrate and die. University and independent testing results prove that Avenger Weed Killer is as effective, but faster acting when compared against leading synthetic herbicides.

When tested against non-organic ‘natural’ herbicides that contain vinegar (acetic acid), citric acid, clove oil or fatty acids (soap), it is more effective with quicker results.

Great for use in & around: Gardens, Spot Control in Lawns, Shrubs, Flower Beds, Driveways, Sidewalks, Patios, Borders, Outside Walls, Mulch Beds, Gravel Beds, Mature Trees & Ornamentals, Greenhouses, Fencerows, Foundations, Buildings, Golf Courses, Athletic Fields, Parks & Recreation Areas, Bike & Hiking Trails, Kennels and Animal Enclosures.

This patented formula works faster than the other leading weed killers, while being safe to children, animals, and the water supply. When Avenger Weed Killer is applied to weeds, it strips off the plant's waxy cuticle, and dehydrates the weed, killing it down to the root. Results are seen within hours. Weeds with a deep root system may require a second treatment or a stronger concentration.

How To Use: 

Shake or mix well before use.  Apply Nature's Avenger Organic to the foliage of the weeds, making sure that all of the foliage is thoroughly wet.  Thorough coverage is necessary to achieve desirable control.  It is best to apply when outdoor conditions are warm and sunny.  Coverage rate varies depending on size of weeds.

Note: All contacted vegetation is affected. Avoid contact with desirable plants. Over-spray or drift will injure or kill vegetation.  To limit spray area, try using a shielding apparatus to surround the weed.  Spray within the confines of the shield.  When removing the shield, do not allow drips to touch the leaves or blades of plants you wish to save.
