Environmental Behavior of the Chiral Herbicide Haloxyfop. 1. Rapid and Preferential Interconversion of the Enantiomers in Soil

, 2016
Haloxyfop-methyl is a chiral herbicide that was first introduced as racemate and later replaced by “haloxyfop-P-methyl”, mainly consisting of the R-enantiomer, which carries the herbicidal activity.

Bioconcentration of haloxyfop-methyl in bluegill (Lepomis macrochirus rafinesque)

Environment International, 1990
Bluegill (Lepomis macrochirus Rafinesque) were exposed to a {sup 14}C haloxyfop-methyl (methyl 2-(4-((3-chloro-5-(trifluoromethyl)-2-pyridinyl)oxy)phenoxy)propanoate) concentration averaging 0.29 {mu}g/L under flow-through conditions for 28 days. At the end of 28 days, the fish were transferred to clean water for a 4-day flow-through clearance period ...
