One of the last organochlorine insecticides, endosulfan, has been undergoing a cancellation and phase-out over the past several years. This product’s phase-out is due to unacceptable risk to farm workers and the environment, as well as persistence in the environment.
The phase-out/cancellation, which began in 2012, will be completed by July 31, 2016. Many growers are familiar with this product under its former names of Thiodan and Golden Leaf, but its current names include Thionex and Endosulfan. Under an agreement with the Environmental Protection Agency (EPA), it is being voluntarily phased out and uses cancelled; various uses will be terminated at specific times. When each of these termination dates passes, it will be unlawful to use these products for those specific uses.
The final termination date is July 31, 2016; the last uses will be eliminated by that date. The phase-out/cancellation schedule is as follows:
|Group F Uses (7/31/16 termination)|
After July this year, there will be no permitted uses of endosulfan. Producers with leftover endosulfan products after this date will need to find a pesticide disposal event in their area to discard these materials. Check with your county Extension office for more information.
