June 2002 - In Australia when Cyhalothrin is used as "- Crack and crevice treatment and barrier strip" no maximum residue levels are required. Ref: June 2002. Table 5.

September 2001 - The pyrethroids discussed in this report are: Bifenthrin (Type I), Cyfluthrin (Type II), Cyhalothrin (Type II), Flucythrinate (Type II) , Flumethrin (Type II), Fluvalinate (Type II), Tefluthrin (Type I).

January 25, 1999 - Sediment Toxicity and Fate of Synthetic Pyrethroids. The synthetic pyrethroids were conditionally registered beginning in 1984 for use on cotton and later for use on other major crops including corn, soybeans, and sugarcane. Currently, EPA is assessing risks to non-target organisms for ten synthetic pyrethroids: bifenthrin, cyfluthrin, cypermethrin, deltamethrin, fenpropathrin, fenvalerate, cyhalothrin, tefluthrin, tralomethrin, and permethrin. Each of these synthetic pyrethroids are conditionally registered for use on cotton, with the exception of tefluthrin, which is conditionally registered for use on corn. Each of these chemicals is highly lipophilic and in aquatic environments tend to strongly adsorb to sediments.
