Interpretive Summary:

Technical Abstract: Table grapes and citrus are among the most important specialty crops cultivated in the San Joaquin Valley (SJV) of California, which is considered one of the most productive agricultural regions globally. Several arthropod pests and pathogens transmitted by arthropod vectors impact table grape and citrus production in the SJV. This presentation highlights research on economically important pathosystems of table grapes and citrus at the USDA-ARS SJV Agricultural Sciences Center. Research on arthropod-borne plant diseases emphasizes the identification of vulnerabilities in vector-host-pathogen interactions as the basis to innovate control tools and strategies. This approach addresses the concern with the development of resistance to chemical pesticides used widely to reduce vector populations for arthropod-borne plant disease prevention. For example, research on viral vectors to express anti-pathogen agents, biopesticides, and pathosystem genomics provide opportunities to develop novel strategies to manage pests and diseases for sustainable grape and citrus production.
