Profile

Dr. Khanal is a nematologist in the Department of Plant and Environmental Sciences at Clemson University. He conducts basic and applied research in nematology with the broad objective of understanding the biology of plant-parasitic nematodes so the knowledge can be utilized for the development of a cost-effective and durable nematode management program. Dr. Khanal also runs a nematode diagnostic lab to help growers, researchers, home gardeners, and related personnel understand the types of nematodes present in their soil, damage potential of the nematodes, and possible nematode management practices. Professional organizations that Dr. Khanal has been involved with are the Society of nematologists (SON), Organization of Nematologists of Tropical America (ONTA), and American Phytopathological Society (APS).

Research Interests

The primary research interests of Dr. Khanal include an understanding of the biology of plant-parasitic nematodes and their interactions with other pathogens and hosts; identification of the source of nematode resistance; development of integrated pest management strategies for established and emerging plant-parasitic nematodes; and dissemination of results to stakeholders. Dr. Khanal is also interested in research employing currently available technologies to find a sustainable solution for current and future nematode management problems. Crops of interest include field crops (cotton, soybean, peanut, grain sorghum, legumes), fruit trees, vegetable crops, ornamental plants, and turf. The ultimate research goal of Dr. Khanal is to safeguard agricultural crops from plant-parasitic nematodes by studying nematode biology, ecology, and epidemiology.

Extension and Outreach

Although Dr. Khanal does not have any formal extension appointment, he is interested in working with extension faculties, county agents, and growers to conduct demand-driven research.
