I am getting ready for "weed season" and I am wondering about using a product like Roundup®
Most definitely stay away from Roundup®. The active ingredient in Roundup® is a chemical
compound called glyphosate. Glyphosate has been linked to birth defects, reproductive disorders,
miscarriages and non-Hodgkin's lymphoma, a type of cancer. Just a month ago, the International
Agency for Research on Cancer (IARC) concluded that there is sufficient evidence that glyphosate
probably causes cancer in humans. Roundup® has also been found to be lethal to aquatic life.
In addition to the active ingredients, Roundup® also contains
"inactive" ingredients, and research suggests that one of these,
polyethoxylated tallowamine, (POEA), is not safe for humans or
other animals and has caused higher instances of miscarriages.
Laboratory research on cows, mice and rats has shown detrimental
effects including kidney and liver damage. Reports abound of pets
that abruptly died after exposure to Roundup® treated properties.
The EPA is conducting a review of Roundup® this year to determine
if the herbicide should be taken off the market. Roundup® is now
off the shelves in much of Canada and France; it is illegal to sell
or apply it for cosmetic lawn care in Ontario. It has been banned in
parts of Argentina, the Netherlands, Sri Lanka, Brazil and in areas
of the United States such as Cape Cod where citizens are strongly objecting to utility company use of
Round-up type herbicides.
Rather than using Roundup, there are several completely safe alternatives for weed killers. However,
like Roundup®, they are all broad-spectrum and kill most everything they touch, so you must be
careful where you spray. Vinegar, citric acid or clove oil are safe "natural" herbicides that kill weeds.
At Sprigs & Twigs, we have used a product called Avenger® Weed Killer for a number of years.
Avenger® Weed Killer has been classified organic by USDA, under its National Organic Program. It is
completely benign to the environment with no toxicity to wildlife, humans or groundwater. Avenger®
Weed Killer smells like oranges and it's all natural, safe and it kills weeds quickly. The active ingredient
in Avenger® Weed Killer is derived from citrus oil which naturally strips away the waxy plant cuticle,
causing it to dehydrate and die. If you would like to try it, we sell a 24 oz. ready-to-use spray bottle
for $11.95 + tax at our Gales Ferry location, 41 Kings Highway, Suite 207. Other sizes, including a
concentrated formula, are also available.
No matter what alternative to Roundup® you use, Roundup® has no place in our stores, our yards
or in our environment.
