- The EPA has given notice to distributors, retailers and pest control operators that products containing chlorpyrifos may not be used for termite control as of the end of this year (12/31/05). The decision does not affect other registered uses for chlorpyrifos. Stocks of products that had been used for pre-construction termite control may be used for other uses after the deadline, provided that they are relabeled. Chlorpyrifos products that do not list pre-construction on their labels are not affected by the measure. (EPA Press Release, 8/30/05).
- Southern Ag is about to release a 4% formulation of atrazine that should be available by mid-October. This is in response to the 40% formulation being classified as restricted (and discontinued). The maximum application is 1.0 pound of active ingredient per acre and a maximum of two applications can be made per year.
