Subject: Dursban™ Insecticide

We have received many inquiries lately with regard to the staus of Dursban™ insecticide, so we have decided to repeat the following update from last season:

While most turf managers have not had access to chlorpyrifos (Dursban™) for several years, the product has been registered for use on golf courses. However, that is in the process of changing.

Below is a notification letter from Dow AgroSciences providing information on Dow Agrosciences' intent to cancel their registration of Dursban™. This will, in most cases, be a phased process so users who currently have access to the material will be able to use product until it is gone. Refer to the letter for specific details.
