Cilantro Production in California

Abstract

Cilantro (Coriandrum sativium), also known as Mexican parsley, Chinese parsley, and coriander, is grown primarily along the southern and central coast of California. Ventura, Monterey, Santa Barbara, and San Benito Counties have the largest production, while smaller areas of production are scattered around the state. In the coastal counties production is year-round, with the main harvest from March through mid-November. Growers in the Coachella Valley (Riverside County) and the San Joaquin Valley plant a winter crop in late September to November for harvest from November through March. Cilantro is often used as a rotation crop; however, some growers may double-crop in a given year. Yields vary greatly. Annual coastal production averages from 8 to 11 tons per acre (18 to 25 t/ha). Cilantro is hand-harvested and sold in bunches to be used as a fresh herb, as well as mechanically harvested and sold in bulk for food service or processing. CLIMATIC REQUIREMENTS Cilantro can be grown under a wide range of climatic conditions. During the summer, the crop matures Vegetable Production Series

Sprinkler and drip irrigation in the organic tomato for single crops and when intercropped with coriander

“…The 15.4% reduction in productivity may have been due to the initial development of the coriander plants having been slower under drip irrigation. This result is supported by Smith et al (2011), who recommend sprinkler irrigation during the initial phase of coriander production in order to improve germination and the establishing of the plants.…”

A Description of the Possible Etiology of the Cilantro Yellow Blotch Disease

“…Since the primary symptoms observed in CYBD-affected cilantro plants in this study were similar to those described for cilantro yellow blotch disease in California (Koike et al 2007;Mayhew 2002;Smith et al 2011), it is conceivable that the California case may also be associated with similar mixed virus infection combinations. Hopefully, this report will stimulate further studies to revisit the etiology of the disease-affected cilantro plants in California.…”

“…Disease incidence at harvest time was estimated at~20% and the affected plants were rendered unmarketable. Due to the symptom resemblance to the California case (Koike et al 2007;Mayhew 2002;Smith et al 2011), we hypothesized that the observed disease in Texas was also likely to be of viral etiology. The goal of this study was to identify the putative etiological agents of CYBD.…”

“…These include bacterial leaf spot caused by Pseudomonas syringae pv. coriandricola, Fusarium wilt caused by the fungus Fusarium oxysporum, carrot motley dwarf disease caused by the coinfection of Carrot red leaf virus (genus Polerovirus) and Carrot mottle virus (genus Umbravirus), Apium virus Y (ApVY) disease caused by the Potyvirus ApVY, and cilantro yellow blotch disease (CYBD) of presumed viral etiology (Smith et al 2011). The causative viruses of carrot motley dwarf and ApVY diseases are vectored by aphids, hence their management relies primarily on the removal of weed reservoirs, and avoidance of fields with a history of the diseases.…”

“…Although CYBD in California was presumed to be caused by a virus, tentatively named cilantro yellow blotch virus, based on the observations of closterovirus-like virions in symptomatic plants (Koike et al 2007;Mayhew 2002;Smith et al 2011), the etiological agent(s) of the disease was never determined. During spring 2019, a virus-like disease resembling CYBD was observed in a 4.05-ha cilantro field planted with cv.…”
