Additional data may be needed before EPA rules on the petition. A. Residue Chemistry 1. The metabolism of dicloran in peaches, lettuce and potatoes has been studied. Parent compound and numerous metabolites derived by hydroxylation and acetylation of the nitro group, along with deamination and hydroxylation of the amino group, were seen in all crops. Glutathione conjugation with simultaneous removal of one or both chlorine atoms was shown to occur.
Parent compound is the only analyte in the tolerance expression.
Magnitude of residues. Tolerances for two other crops in Crop Group 4, celery and rhubarb, also exist. B. Toxicological Profile 1. Dicloran is not a dermal irritant but is a sensitizer. Dicloran is a mild eye irritant.
