Objectives: 

The objective of this research was to collect samples of carrot roots from soil in which ethoprop had been applied. Samples from the treated plot were to be analyzed for ethoprop residues and compared to untreated samples from the same field. The results were to be used to establish a residue tolerance level for carrots. The data collected from this field study was to become part of a petition to be submitted to EPA by IR-4 requesting that a national residue tolerance be established for ethoprop (MOCAP) in carrots.
