Avenger Ready-To-Use and Concentrate Burndown Weed Killer


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.

Avenger Weed Killer is registered for sale in all 50 states.
