Avenger is a non-selective weed killer for weeds and grasses in rock bed and mulch areas.

Avenger is an all-natural, non-selective herbicide for broadleaf & grass weeds and a natural alternative to products like Roundup

Avenger Natural Weed and Grass Killer is a non-selective, post-emergence herbicide, which means it quickly and effectively kills weeds and grasses that it comes in contact with. Avenger is the best non toxic weed killer that will kill undesirable plants 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 and is a natural grass killer. University and independent testing results prove that Avenger Weed Control is as effective at killing plants as chemicals, 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 at killing weeds and grasses, but with quicker results. Try this fantastic all natural herbicide for your rock or mulch area weed control at your Boulder or Fort Collins area home or business today!
