The International Cancer Agency, from the World Health Organization, considers 2,4 D broad leaf herbicide a possible carcinogen because it causes oxidative stress. This can lead to chronic inflammation and cancer in humans. 2,4- D is the most commonly used pesticide in the world, marketed as Weed B gone, Tri Kill, Killex, Weedaway Trillion and Par 3 to name a few. Last year, it was marketed as Enlist Duo, combined with glyphosphate by Dow AgroSciences. It is part of Agent Orange, mixed with dioxin. Alone, it has been used since World War Two. Previous concern is it causes cirrhosis of the liver, especially in golfers.Chemical manufacturers are disputing the classification of a possible carcinogen from previous studies. In other words, it may not cause cancer in everyone exposed to eating food grown during its use. Environmental agencies, such as the Natural Resources Defense Council are filing lawsuits to discontinue its use. What are you spraying on your lawn and garden?
