Cilantro was produced on 5,543 acres in Monterey and Ventura Counties in 2011. The production of cilantro has shifted to high density 80-inch wide beds and a large proportion is now mechanically harvested. Hand weeding high density beds is very expensive and reduces the economic viability of this crop. As a result, there is a need for excellent weed control. Two broadleaf herbicides were registered on cilantro: Prefar and Caparol. Prefar was registered for a number of years and provides good control of a number of key weeds in cilantro such as purslane, lambsquarter and pigweed.

Given that cilantro is a very minor crop, the label was ultimately grouped with carrots, parsley and okra in order to attract more attention for the label request, and so that it would not get lost amongst the many other label requests that EPA deals with. The packet was ultimately processed and sent back to Syngenta, and in...
