Documented Uses

• For control of thrips and caterpillars in ornamentals.
• Groups of 3 Sprague-Dawley (Crl:CDBR) rats/sex/group were dosed with pyridalyl of high purity, to which labeled pyridalyl (either phenyl or propenyl-labeled) pyridalyl of at least 97% purity was added to achieve 5 or 500 mg/kg single gavage doses at 50 uCi/rat. The study evaluated radioactivity in many tissues sampled at 4 times (based on results of Record No. 242040): 1/2 Cmax (absorption), Cmax, 1/2 Cmax (elimination), and 1/10 Cmax (elimination). These sampling times were 4, 8, 24, and 48 hrs for 5 mg/kg phenyl
