Avenger Weed Killer is a citrus oil-based herbicide designed to meet the demands and needs of homeowners and businesses looking for an alternative to synthetic herbicides or less effective "natural" weed killers. Environmentally friendly, Avenger is fast becoming the weed killer of choice for those interested in organic gardening or who want to use a product that is kind to the environment. "What makes Avenger® Weed Killer different from the leading synthetic herbicide and all those supposedly "natural" weed killers on the market?"  After all some of the others state that they are "natural" and/or "organic"? Well, first off we are proud to say Avenger Weed Killer is an EPA registerd product.  This means we've gone through the rigourous process of having our product tested and registered with the EPA.  This also means, all of our claims have to be substaniated and proven to be allowed on our label and on this website. Next Avenger Weed Killer has been Approved for Use in Organic Gardening/Organic Production by the USDA National Organics Program.  To prove this we are allowed to put this seal on our labels and in all our advertising and marketing.   Other products making these claims would also have this seal or a "For Organic Production" seal on their labeling.  If they do not, beware. Avenger Weed Killer is also OMRI Listed (accredited by USDA National Organics Program).  OMRI provides organic certifiers, growers, manufacturers, and suppliers an independent review of products intended for use in certified organic production, handling, and processing. OMRI reviews products against the National Organic Standards. Acceptable products are "OMRI Listed®" and appear on the OMRI Products List. (OMRI achieved USDA accreditation under International Organization for Standardization Guide in January 2008) Avenger Weed Killer is fast acting - often seeing visible results in 2 hours or less!  Tested against the leading synthetic herbicide glysophate, Avenger has proven to be just as effective, but faster acting.  Tested against other organic or "natural" products on the market,  Avenger was the proven winner time and time again. How does Avenger work?  Avenger's patented formula is made with natural citrus-oil (or d-limonene for those who want to know the technical name).  D-limonene (citrus oil) is a natural degreasing agent that strips the weed of its waxy skin (cuticle), causing it to dehydrate and die. Our emulsion technology allows you to see where you've sprayed and sprayed areas can be re-planted within hours.  Avenger also works in cool and cloudy conditions (as low as 40º F) and is highly biodegradable.  Avenger is also considered GRAS (GRAS=Generally Recognized As Safe). And finally, since Avenger Weed Killer is made from citrus fruits, it has a fresh citrus aroma.  No other weed killer can boast all of these facts.
