Abstract: A composition for treating a citrus tree having citrus greening disease includes an antibiotic, at least one micronutrient, water, and a bark penetrating surfactant like organosiloxane surfactant that is absorbed through the bark periderm and enters the lenticels of the tree. The antibiotic is one effective for treating a gram negative bacteria like HLB and is preferably tetracycline. The micronutrient can be zinc, manganese, or iron (and is preferably all three), and the zinc and manganese can be in sulfate form to serve as a bactericide. A pH adjusting compound such as ammonium sulfate can be included to adjust the pH of the water. A method of treating citrus greening disease using the composition includes the step of applying the composition onto the bark periderm of a citrus tree. The applying step results in the composition entering the vascular system of the citrus tree.
