Well, on my own, I saw a problem with a citrus tree and I contacted the Dept of Ag, and they did come out, test my tree. It DID have the Asian Citrus Psyllid, but it was not carrying the disease! Whew! These are nice people protecting our crops.
IF it would have tested postive for greening. They would have ripped every citrus out of my yard, and I might not think so kindly of them.
They told me to use Bayer Imacloprid (and we do, not cheap) to prevent the spread. We have used that forever on our vineyard to prevent the glassy sharpshooter!
Just a side note, shopping for citrus retail, every one has a tag! Quarantine. Do not take this plant out of Riverside County.
They protect us and our crops. Not bad guys at all!
