Abstract: ABSTRACT TITLE: A METHOD FOR MANAGEMENT OF HUANGLONGBING (HLB) OF CITRUS AND CONTROLLING VECTOR-BORNE DISEASES IN PLANTS BY DISRUPTING ENDOSYMBIONT COMMUNITIES IN INSECT VECTORS THROUGH HOST-MEDIATED TREATMENT 5 A method for controlling vector-borne diseases in plants by disrupting endosymbiont communities in insect vectors through host-mediated treatment. The method comprises sequential application of six components: (1) nano-biocide formulation containing nanoparticles of silver or other metals; (2) consortium of plant growth promoting rhizosphere microbes; (3) plant extract from Karanj (Pongamia glabra); (4) slow-release formulation comprising amino 10 acids, seaweed extracts, humic and fulvic acids; (5) foliar spray comprising nitrogen-fixing bacteria with folic acid and thiazolidine carboxylic acid; and (6) silicone-based wetting and spreading agent. The treatment restores host plant health, disrupts the vector's endosymbiont community (Carsonella ruddii, Profftella armatura, Wolbachia), reverses pH alterations caused by the pathogen, re-activates the host plant's innate immune system by reducing pathogen-15 mediated suppression, and results in behavioral changes in the vector including sluggishness, feeding cessation, and reduced vector competence. The method is applicable to multiple crops and vector-borne diseases including Huanglongbing (HLB) of citrus vectored by Asian citrus psyllid (Diaphorina citri), brown plant hopper in paddy, aphid-transmitted viruses, leaf curl viruses in solanaceous crops, and xylem-borne diseases caused by Xylella fastidiosa including 20 Pierce's disease of grapevines, Olive Quick Decline Syndrome, citrus variegated chlorosis, almond leaf scorch, and coffee leaf scorch, vectored by sharpshooters (family Cicadellidae), spittlebugs (family Aphrophoridae), and froghoppers (family Cercopidae). Field trials demonstrate 5-6× yield increases, vector-free periods of up to 7 months, elimination of pathogen titer to below detectable levels within 8 months, and restoration of ecological balance with 25 increased presence of natural predators.
