Abstract

Parsley (Petroselinum crispum Mill.), cilantro (Coriandrum sativum L.), and dill (Anethum graviolens L.) are grown on minor acreages in Florida, but are a major part of many fresh market mixed-load shipments to northern markets. Registered herbicides on these three crops are few. Trials were established in Hendry County, FL, at C&B Farms in Dec. 2006 and Feb. 2007 to evaluate several herbicides on dill, parsley, and cilantro grown on mineral soils. Treatments consisted of PRE applications of metolachlor (Dual Magnum), dimethenamid (Outlook), and pendimethalin (Prowl H2O). In 2006, prometryne (Caparol) was applied at three rates PRE. In 2007, prometryne was applied two rates PRE and POST. Linuron (Lorox) was applied at one rate PRE, one rate POST, and two rates PRE plus POST. There were differences in tolerance among the crops to a herbicide and differences in tolerances to the herbicides of the crops. The crops were least tolerant to dimethenamid applied PRE. No stand reduction or stunting was seen in the three crops in the metolachlor and Prowl H2O treatments. Some problems were observed with other materials especially at higher rates.
