Parsley is placed in the "leafy greens" EPA group for residues because of its closeness to lettuce and spinach. Check Weed Control in Leafy Greens (https://edis.ifas.ufl.edu/wg031) for possibly more labels. Bensulide may be preplant incorporated to parsley or applied preemergence on mineral soils.

Linuron is labeled for weed control in parsley (Table 1). The label for linuron is relatively new, and the material should be used on a trial basis until experience is gained as to rates and timing at specific locations. Linuron may be applied as a postemergence application over parsley in muck soils only.

Cilantro was included in the 2009 Pesticide Data Program. One hundred and eighty-four samples were collected from stores across the United States. The USDA analyzed the 1 lb. samples for all pesticides, including fungicides, insecticides, and herbicides. This EDIS publication includes only herbicides. The herbicides detected were dimethenamid (0.7% of samples), fluazifop butyl (0.5%), linuron (15.2%), metolachlor (1.1%), pendimethalin (6.5%), and pronamide (0.5%). All herbicide residue levels were below the allowable residue level for other crops. The report concludes a possible confusion between chemicals registered in parsley, but not in cilantro. Of the six herbicide residues, linuron is the only herbicide registered in parsley. Read and follow all label directions.
