My viticulture program focuses on informal education, field research and problem diagnosis. Meetings, county publications and newsletters are included. With cooperation of the Lodi-Woodbridge Winegrape Commission (LWWC), we conduct regular grower meetings as well as the annual Lodi Grape Day that helps inform growers and the community about the latest progress in research. Another successful educational effort has been the LWWC breakfast meetings, where monthly group meetings are literally held in farmers' homes to discuss methods, utilizing Integrated Pest Management (IPM), irrigation, and grape production. Field research includes experiments in resistant rootstocks for soil pests, variety and clone evaluation trials, trellis system comparisons, pest management with environmentally safe chemicals, and vineyard irrigation management for increased quality.
