One concern I have is that if Casimiroa was infected somewhere in SoCal that seeds of fruits produced from those trees might make their way up into NorCal and get planted since several of us up here have done this in the past. Still, it's such a rare species up here my level of concern is quite low. It's just something I'm keeping in the back of my head (figuratively).

From what I have read and heard the Psyllids don't like Casimiroa, if you give them no choice they will use it as food, but they don't reproduce on it. If they don't feed on it they can't transmit it. I haven't seen any reports of White Sapote having HLB.
