Research in Dr. Kennedy’s program focuses on understanding the ecology and life systems of arthropods affecting agricultural crops and applying that understanding to improve the effectiveness and sustainability of arthropod management in vegetable crops. He studies fundamental interactions and processes that influence pest status, population dynamics and the insect/crop interactions that result in damage.  He applies the resulting information in combination with new technologies to enhance IPM. Areas of emphasis include insect-plant interactions, resistance management, landscape scale population dynamics, and epidemiology and management of insect transmitted plant viruses. Current research projects focus on understanding the determinants of tospovirus transmission by thrips in relation to epidemiology and management of Tomato spotted wilt virus and on the development of reduced risk arthropod management systems for fruiting vegetables. These efforts include both field and laboratory research and collaborations with faculty in Entomology, Horticulture and Plant Pathology at NCSU and colleagues at other institutions.

Georgia vegetable growers need effective integrated programs to control troublesome diseases on vegetables due to limited efficacy of current disease management techniques. Dr. Langston’s UGA plant pathology extension program assesses and integrating pesticide products, host resistance and cultural practices to reduce the impact of Phytophthora blight, southern blight, gummy stem blight, tomato spotted wilt and other important vegetable diseases. He has identified several promising tactics that have the potential to significantly reduce losses caused by these major diseases.

My research interests include the detection and identification of bacterial and viral pathogens, the ecology of bacterial plant pathogens and the epidemiology of both bacterial and viral diseases. My lab has most recently focused on Pantoea ananatis and P. agglomerans (thrips-vectored bacteria that are part of the center rot of onion complex), Burkholderia cepacia (sour skin of onion), Acidovorax avenae subsp. citrulli (watermelon fruit blotch), Iris yellow spot virus and Tomato spotted wilt virus (thrips- vectored viruses in the Tospovirus group). Management strategies of interest include seed health assays, crop rotation schemes with suppressive hosts, solarization, SAR compounds and adjusting micro-nutrient ratios to increase plant disease resistance.

Extension includes the development and implementation of IPM programs on fruits and vegetables in Western North Carolina. Emphasis is placed on pests of apples, staked tomatoes and cabbage. The objective is to expand the use of new pest control technology and enhance the pest control decision-making process by growers through the use of traditional extension publications, electronic information transfer technology, grower meetings and a series of on-farm tests and demonstrations. Also serve as a source of information and services for the non-agricultural residents of Western North Carolina.  Specific research problems being investigated on vegetables include population dynamics of thrips and epidemiology of TSWV, and effects of sustainable agricultural practices (i.e. cover crops, ground covers, etc.) on pest and beneficial insects in vegetable systems.

My research focuses on the ecology and management of insect pests of commercial vegetable crops in North Carolina. Major emphasis is placed on providing science-based information to address problems in insect pest management and enhance the effectiveness of the vegetable extension program at NC State University. Primary interests are in developing/refining economic thresholds, managing insecticide resistance, and improving sampling procedures in agronomic systems. Tomato spotted wilt is an insect vectored viral disease of fruiting vegetables in the Southern US. The disease has the potential to cause severe economic losses in years of high virus/vector incidence. My lab is currently involved in a multistate, multidisciplinary research and extension project funded by USDA’s Risk Avoidance and Mitigation Program with the goal of developing improved tactics for managing the disease and the thrips that vector it. Cultural and chemical controls and host plant resistance are being evaluated.

Our program is rooted within core values associated with a sustainable agriculture framework and is service-oriented, consistent with the mandate of a Land Grant University, with emphasis on strawberries, tomatoes, peppers and organic crops. Our disciplinary strengths are in bacteriology, soilborne pathogens, plant disease management, microbial ecology and farming systems research. A key strength of the program is the ability to understand real-world problems within a production agricultural framework and by asking strategic questions that advance the sciences of plant pathology, horticulture and systems research in organic and conventional production systems.

I have been Professor and Head of the Department of Plant Pathology since 2002.  The Department has approximately 30 tenure and nontenure (USDA) faculty that direct a diversity of programs from the mission oriented to discovery research supported by federally funded competitive research grants, contracts from corporations as well as state and national commodity organizations. The Department is also home to the Plant Disease and Insect Clinic which serves the diagnostic needs of plant industries in the region as well as the MicroPropagation Unit and Repository that serves as a source of clean stock planting material for sweetpotatoes, strawberries and other fruit crops.  Faculty mentor graduate students in Plant Pathology as well as a number of interdisciplinary programs.  While the faculty serve as Principal Investigator, over 45% of their funded research is from interdisciplinary projects.

I have worked for most of my career with IPM and have developed several educational programs to teach growers and consultants about the sampling practices, management issues, and crop suitability of several IPM approaches. In this USDA project we investigate the factors contributing to the disease in the region, evaluate current management recommendations, develop new recommendations, and determine the disease risk for a site prior to planting the crop. Major components of this project are on-farm testing and demonstration of current practices, newly developed practices, and the collection of extensive weather and thrips activity data from these farm areas. Grower education seminars have been held at local and regional winter production meetings and conferences, web-based questionnaires and informational portals have been developed to allow for grower input and added educational opportunities, and hands-on opportunities have been made available for learning more about this important problem.
