Instructions for holding plants entering San Luis Obispo County from Glassy-winged Sharpshooter (GWSS) infested counties for inspection.

It is important that you request an inspection and follow these step-by-step instructions:

• Look for a "Blue Hold Tag" with the invoice. The hold tag is required for all plant shipments coming from GWSS infested counties.
• Unload plants to a location that minimizes exposure to existing plants and allows inspectors access.
• Do not plant or stage the plants.
• Keep plants and accompanying paperwork at the site until an inspection is complete.
• Do not spray foliage with water.
• Contact any of the three Department of Agriculture/Weights and Measures Offices to set up an inspection.
• Please include the address, any gate codes, phone numbers, and relevant information necessary to access the plants. You may also call ahead to arrange a specific inspection time. 
• Staff will typically arrive within two hours for GWSS inspections.
• Staff will inspect plant shipments for viable GWSS egg masses, nymphs, and/or adults and verify the required certification accompanies the shipment.  If the plants are free from GWSS and other invasive pests, they will be released for sale or planting.  Your invoice will be stamped with a green and white "PASSED CALIFORNIA AGRICULTURE" sticker.  Please retain this documentation for two years.
