THIS INTEGRATED PROJECT, A PARTNERSHIP BETWEEN RESEARCH AND EXTENSION SPECIALISTS AT THE UNIVERSITY OF GEORGIA, CLEMSON UNIVERSITY, AND USDA-ARS, AIMS TO DEVELOP SUSTAINABLE MANAGEMENT PRACTICES FOR CONTROL OF SOUTHERN ROOT-KNOT NEMATODE (RKN; MELOIDOGYNE INCOGNITA), BACTERIAL WILT (CAUSED BY RALSTONIA SOLANACEARUM), SOUTHERN BLIGHT (CAUSED BY ATHELIA ROLFSII), AND WEEDS IN TOMATO PRODUCTION SYSTEMS IN GEORGIA AND SOUTH CAROLINA. THE OVERALL GOAL OF THE PROJECT IS TO INTEGRATE EITHER NON-FUMIGANT NEMATICIDES OR ANAEROBIC SOIL DISINFESTATION (ASD) WITH GRAFTING ONTO ROOTSTOCKS WITH RESISTANCE TO MULTIPLE PATHOGENS TO DEVELOP AN EFFECTIVE MANAGEMENT PROGRAM THAT GROWERS CAN ADOPT FOR TOMATO PRODUCTION. THIS PROPOSAL ADDRESSES ONE OF THE PROGRAM PRIORITIES, "HOW CAN CURRENT METHYL BROMIDE ALTERNATIVES BE IMPROVED OR COMBINED TO IMPROVE THEIR EFFECTIVENESS AND ECONOMIC VIABILITY?" WE WILL EXAMINE THE EFFICACY OF SOLANUM SISYMBRIIFOLIUM AS A RESISTANT ROOTSTOCK FOR CONTROL OF RKN, BACTERIAL WILT, AND SOUTHERN BLIGHT. OUR PRELIMINARY RESEARCH DEMONSTRATES THAT S. SISYMBRIIFOLIUM IS RESISTANT TO MULTIPLE MAJOR SPECIES OF RKN. WE WILL DETERMINE IF COMBINING GRAFTED TOMATOES WITH NEMATICIDES OR ASD WILL IMPROVE CONTROL OF SOILBORNE PESTS. WE WILL CONDUCT COST-RETURN ANALYSES TO DEMONSTRATE THAT OUR INTEGRATED MANAGEMENT PRACTICES ARE PROFITABLE TOOLS FOR TOMATO GROWERS. WE WILL USE OUR ESTABLISHED EXTENSION PROGRAMS TO COMMUNICATE OUR RESULTS TO STAKEHOLDERS. OUR INTEGRATED RESEARCH AND EXTENSION ACTIVITIES WILL LEAD TO EFFECTIVE MANAGEMENT STRATEGIES TO REPLACE CURRENTLY USED METHYL BROMIDE ALTERNATIVES, PROTECT THE TOMATO INDUSTRY FROM SOILBORNE PESTS, AND IMPROVE TOMATO PRODUCTION.
