Classification:
EC Risk Classification: Xn - Harmful: R43

ENVIRONMENTAL FATE
In the loamy sand soil, [14C]cloquintocet-mexyl decreased from an average 98.90% of the applied at 0 days posttreatment to 41.62% at 0.21 days, 11.20% at 1 day and 5.33% at 56 days. In the silt loam soil, [14C]cloquintocet-mexyl decreased from an average 48.16% of the applied at 0 days posttreatment to 23.69% at 0.21 days, 9.26% at 1 day and 1.97% at 56 days. Cloquintocet-mexyl degraded with a DT50 of 0.2 days in both soils using a two-compartment model with MicroCal Origin. The DT50 for the transformation product CGA 153443 was determined to be 5.5 and 9.7 days in the loamy sand and silt loam soils, respectively. At study termination, [14C]residues trapped in the NaOH solution totaled 5.69% of the applied from the loamy sand soil and 13.01% from the silt loam. These residues were characterized as 14CO2, by the study author; no methodology was provided to determine if the identification was definite or assumed. No data were provided on volatile organics were not reported.
Usage: Manufacturers: Syngenta. A herbicide safener used to improve cereal crop tolerance to the herbicide clodinafop-propargyl.
Application: Effective to alopecurus aequalis sobol, wild oat and Annual Bluegrass. Non-effective to broad-leaf weed.
