If a citrus tree is in a Citrus Greening area such as Florida with active ACP, the chance of the tree getting citrus greening is about 100 percent. You can spray all you wish but it is still about 100 percent. All it takes is just one infected psyllid bite. HLB presently has not cure. The only treatment to insure that a citrus tree will not be infected would to build a screen around the tree to keep the psyllids from ever landing and feeding on the tree.

If it is infected, just destroyed it.The more knowledge gain, the more worries about the citrus tree
