There is a slowly spreading but totally deadly citrus disease out
there that poses a very real peril for the entire industry. Known
by an abbreviation
HLB from the Chinese huanglongbing, the disease is carried by
an aphid and kills the trees and renders the last fruit inedible.
It's in Florida and Brazil so far, and just recently the
aphid that could possibly carry the disease-but didn't this
time- was discovered in Tijuana, Mexico, meaning it could be
getting closer to the California groves.
About a week and a half ago, U.S. Customs and Border
Protection officials at the San Ysidro Port of Entry identified
one of the bugs catching a ride across in a bouquet.
California oranges are mostly eating oranges. Orange juice
comes from Florida and Brazil more than anywhere else.
When I lived in Florida, going to a grocery store you'd see a
dozen different types of oranges. Apples were granny smith,
golden delicious and red delicious. That was pretty much
it.
When I moved to Washington (State), it was the opposite.
Dozens of varieties of apples. But for oranges there were
California navels, and that was pretty much it. Easy to
peel, but very bland and dry compared to what I was used to from
Florida.
So, if the aphid is in Florida and Brazil, OJ is already in deep
juice. If it hits California, we're going to see eating
oranges take a hit.
Considering that the psyllids found weren't infected,
isn't this rather like spotting a rat and then worrying the
bubonic plague is making a come-back?
Obviously a psyllid presence is a prerequisite for Huanlongbing
to spread, but even given their presence (which so far hasn't
been demonstrated), it's not a given that it will. It also
doesn't seem to be that hard to treat.
This story strikes me as a lot of worries over nothing.
Yes, they haven't found it in California yet, but where it
has spread they keep finding new infestations of it. It appears
it is not quite as easy to get rid of as one might think. the
reference URL in the article goes to an official cal citrus site
where they are treating the possibility of it occurring
seriously. http://www.californiacitrusthreat.com/ Here is a US ag
department writeup where a research proposal for HLB studies was
the "top ranked" one they had for 2007 granting
(proposal written in 2006).
http://www.ars.usda.gov/is/pr/2006/061109.htm Here is some more
on the general alert gowing out, because finding an active
infected host triggers an automatic and severe quarantine (where
tht previous link came from, that task force just started). That
quarantine would extend beyond citrus and into any host plant
species that could carry the insect.

So, it looks to be a big deal so far. They just don't want it
to turn into a bigger deal.
Off the wall, just on the subject of pesticides and so on, I was
reading more about that in general last night, of the around
1,000 known serious pests, none of them are eradicated yet with
pesticides/sprays, whereas a host of harmless species have been
severely effected.
Invasive species is one of the basic dangers we need to deal with
for global trade- personally I think it's a cost that has
been socialized that the importing corporations need to start
paying for in the form of some sort of insurance.
