The Citrus Pest and Disease Prevention Program (CPDPP) reports that grower participation remains high amid concerns of participation.

Southern Stanislaus County has been placed under quarantine for the Asian citrus psyllid (ACP) following the detection of two ACPs within the city of Turlock. The quarantine also takes in a portion of northern Merced County along its border with Stanislaus County. The quarantine zone measures 101 square miles, bordered on the north by East Service Road; on the south by August Avenue; on the west by Blaker Road; and on the east by North Hickman Road. The quarantine map for Stanislaus and Merced is available online at:

The quarantine prohibits the movement of citrus and curry leaf tree nursery stock, including all plant parts except fruit, out of the quarantine area and requires that all citrus fruit be cleaned of leaves and stems prior to moving out of the quarantine area. An exception may be made for nursery stock and budwood grown in USDA-approved structures which are designed to keep ACP and other insects out. Residents with backyard citrus trees in the quarantine area are asked not to transport or send citrus fruit or leaves, potted citrus trees, or curry leaves from the quarantine area. Read more from
