These are the first salvos, of what could become a economy changing event. -I have thought about the future of California Citrus nurseries/propagators, such a Four Seasons Growers and others, if or when, a California quarantine should ever be put in place. If there are any citrus varieties a person might want to obtain, now might be a good time to purchase them. Millet

Well it is not like we should be surprised. We all knew that it was coming. What we have now to do is to try and stem the spread and save the citrus while those that can try to find a way to eradicate the bug or the disease.......It is not something that can not be done. Destruction has hit citrus before and it has survived.....................its a shame but it is just another obstacle that smart folks will have to overcome...............David

The nurseries in other states will soon be doing what FL nurseries are doing--propagation in screen enclosures. If we want to have citrus in our yards we may have to do the same soon.

At least we won't have to heat the screen enclosures.

This is true. I really hope that it does not come to that but it may. If it does I see a real "end" to citrus as we know it. I dont know how the folks make out where the p came from but I hope that someone finds a way to continue propagating and enjoying citrus as a hobby and an industry..............Daivd

Of course being in Colorado, I'll never have to worry, but a lot of the tree sales for California nurseries, like Four Winds Growers are outside of the state of California. As in Florida, all sales outside of the state will be restricted, and possibly even some areas within California, screen house or no screen house. They possibly can ship all their product to Canada. - Millet

I may be naive, but I don't really think something like this will become a problem for me since I live in fairly open country without many other citrus trees close to me. Hopefully, it will be a long time for such a best to come my way.

Unfortunatly Harvey, I think the psyllid is very mobile. They are small and they must just ride the wind to have covered the territory that they have covered in such a short time.

I was hoping that it would be some time before they were here in NW FL because we are upwind of the major citrus areas in FL, but when I heard they were in TX and LA, I knew they would be moving east. Now that they are in MS and AL, I am sure they will be here soon if not already.

I was surprised to see that they were already in SC, but GA was not unexpected.

Next question is how long will it take for greening to show up in the same areas?

That's what they said about the Med fly and the gypsy moth. It is so easy to hitch a ride from down south to here. With insect's massive amount of eggs, they could have a mutation that will be favored to adapt to the patterns of the northern California, as where there is citrus growing, so will the pest be showing. It is only a matter of time for selection pressure to work on, so that they will adapt to here. Being helped by changing climatic patterns, they could be boosted up here when a series of above average warm winter years will help them deliver the pathogens to cause damage. But I am ready. I have rootstocks that are resistant to HLB, and plenty of cheap (from dollar tree stores) aspirin and backup willow trees (from friends) to help the trees, just in case.

From what I read Trifoliata is resistant, but what do aspirin and willow do for greening ?

Laaz,

I posted several articles about how one Florida farmer is able to successfully combat greening diseases and his citrus grove remained productive. He used salicylic acid, the same type of ingredient for making aspirin, same type you can get from willow trees. His trees were shown to have the greening disease but showed no decline because of his spray regimen that included "aspirin" and micronutrients to help the citrus plants maintain vigor and remain productive. Many scientists went to his farm to investigate and there are formal scientific trials being conducted related to what he has done.

Maybe you can dig those old articles up which I filed under Citrus News.

Thanks Joe. I found them.

Joe, I hope your correct. Salicylic acid might be beneficial for the control/cure of HLB. or it might not be beneficial, I don't know. However, I cannot help to think if the answer to greening was so simple the scientists at UCR, the University of Florida and USDA would know all about salicylic acid and would have published something by now. I always think the same thing when a person tells me of their miraculous cure for a tragic disease, I always wonder why the cure is unknown to the Mayo Clinic. Just some thoughts - Like I say, I'm certainly no expert on citrus greening. - Millet

Joe, the spread from Tiajuana to San Diego is across very populated areas, not across many miles of land with mostly grain fields. I have to believe that they will typically fly to an area where they can reasonably find a host. Chestnut blight is also mobile and an orchard 40 miles from me has had it for many years, but it has not spread to anywhere near me. Insects that hitch a ride on vehicles usually are in the form of eggs and later hatch after the cargo is unloaded at its destination. For instance, early in my sister's career she discovered a gypsy moth egg mass on a swing set when people moved to California. Where were the Medflies found? - a populated area. I would not be surprised if the pysillid arrives in Davis but honestly think it's much less likely to arrive here at my place anytime soon.
