December 31, 2004 is the last day outdoor lawn and garden products containing the pesticide diazinon can be sold. After that the products will be pulled fro the shelves. Indoor pesticides containing diazinon were banned two years earlier.
What Products Contain Diazinon
Diazinon has been one of the most widely used pesticides by homeowners. Prior to its banning in 2002, diazinon was the active ingredient in many household ant & roach sprays as well as pet flea control products. It was particularly popular as a grub control for lawn care. According to Extoxnet, ceasing the sale of diazinon containing household and lawn and garden products will “...eliminate 75 percent of the use which amounts to more than 11 million pounds of the pesticide used annually”
How Does it Work
Diazinon belongs to a category of pesticides known as organophosphates (OP). OP pesticides interrupt the target's nerve impulses along the central nervous system. This causes convulsions, paralysis, and eventually death.
Although OPs are biodegradable and relatively short-lived, at certain doses they have been shown to be toxic to birds, fish, animals and even humans. Other commonly sold OP pesticides include: Acephate, Chlorpyrifos, Malathion and Trichlorfon.
Why is It Being Banned?
According to the Environmental Protection Agency (EPA), “Organophosphates can affect the nervous system. The effects from diazinon vary depending on the dose, but symptoms from over-exposure can include nausea, headaches, vomiting, diarrhea, and general weakness. Today’s action also represents an important step for the environment. Diazinon’s use on turf poses a risk to birds, and it is one of the most commonly found pesticides in air, rain, and drinking and surface water.”
What Do I Do With the Products I Have?
Homeowners who already have products containing diazinon are still permitted to use them, although they are cautioned to always read and follow the label directions and precautions. If consumers wish to dispose of their diazinon products, they should contact their state or local hazardous water disposal program or the local solid waste disposal service for instructions on the proper methods.
