The Umbelliferous Crops that are grown in California include carrots, celery, and parsley. Carrots are grown on about 23,000 acres. Weed control costs for carrots are about $30 per acre and losses are estimated at $7.50 per acre for a total loss of $860,000 per year to California growers. Most, of the estimated cost of weed control in carrots comes from the use of selective aromatic oil and hand hoeing.
