Please elaborate a bit on the vector thing. I was told no fruit from Florida as they have had asian citrus psyllid for a while and it is coming up from Mexico. They found it in La Habra so no citrus from there to enter Long Beach.

The Asian citrus psyllid (ACP) is a pest that acts as a carrier or vector spreading "huanglongbing" (HLB), a devastating disease of citrus trees. This bacterial disease is transmitted to healthy trees by the psyllid after it feeds on infected plant tissue.

thanks to Bruce Goren from Golden Gate CRFG for alerting us to this.

We have our own problem is South Florida with a a similar borer, deadlier. The vector of Laurel wilt is a type of Ambrosia Beetle. This originally came (is theorized) in the hull of a cargo ship docking in the Carolina s from Japan. It took a few year to get from the Carolina s to Florida, it attacks avocados, part of the laurel family. At this time it is active in the area. This is a potentially fatal disease for the industry, we in Florida had 3 years plus to prepare and the time was not used properly, there are solutions but not simple and costly, with label problems etc. This eventually will get to the West Coast. I understand is moving along the gulf states I hope the west coast growers put the resources now to deal with this.
The next few months will be crucial for us in Florida.
In today's world, is not enough to ban importation of this and that, some of these beetles fly more than 15 miles a day. It can fly into the cargo hull of a plane and be 1500 miles away in 3 hours. It could bore into wood on a train, lay eggs etc.
Coordinated research and planing is what is needed to deal with all these diseases and to use the time wisely. That is the reality of the world we live in.

This pest is a looming danger here in Southern California, as it could also decimate our native California Bay Laurals (aka California Bay Leaf) as well as our Avocado orchards.

Mike I did not realized you also have laurel trees in Ca. The non fruit bearing trees can be treated with propiconazole, the injectable type like Alamo, now is available generic. The fruit trees is another issue.

Excuse my blondness... injectable! How do you inject a tree? Also what would you use on a fruit tree?

Thanks bunches

Rhaps, tree injections have been in use for many years. Google it and you will see.
For Laurel Wilt in ornamental you can use propiconazole but the formula of propiconazole approved for avocados still in a questionable state as to its effectiveness as it relates to protection and cost feasibility in a commercial situation.
