A dairy cattle feeding study was submitted. Four treatment groups of four dairy cows each were dosed orally for 28 consecutive days with florpyrauxifen-benzyl. The average dose levels of florpyrauxifen-benzyl based on concentration in the diet (DM feed basis) were 2.58 ppm, 13.1 ppm, 23.9 ppm and 110.8 ppm. For beef and dairy cattle the estimated maximum livestock burden for florpyrauxifen-benzyl is 2.40 ppm, based on a diet of 100% rice forage. The predicted residues of florpyrauxifen-benzyl in the milk and tissues of cattle fed with a 2.4 ppm dietary burden are shown in Table 6 Table 6: Predicted residues of florpyrauxifen-benzyl in the milk and tissues + XDE-848 2.58 <0.02 <0.02 <0.02 <0.02 <0.02 2.40 beef and dairy, estimated burden <0.02 <0.02 <0.02 <0.02 - – Recommended MRLs *0.02 *0.02 *0.02 *0.02
