milknsky, I answered you over on the GW Citrus Forum, so same answer here: standard procedure for us in California. All citrus sold in retail nurseries will be treated, inspected and certified. They will all have this label. Since you're in Los Angeles county, you'll not want to take your citrus outside the county per our CDFA regulations. So, not to worry, this is normal to see on all citrus trees for sale. You WANT to see that label on your citrus tree you purchase
