Her lab is interested in food quality aspects of agricultural systems, looking at food’s secondary metabolites, metabolomics and lipidomics. Main research topics involve interdisciplinary collaborations, e.g. in studying the effects of water quality and nutrient availability on food health properties.

Soilborne Diseases

Omer Frenkel, Ph.D., is a Senior Research Scientist in the Department of Plant Pathology & Weed Sciences, The Volcani Center, ARO. Omer’s research is focused on two main aspects: i) Population biology of plant pathogens, and especially the ecological factors that depict the populations divergence. This research field involves several pathosystems including grapes/Erysiphe necator and Avocado/Lasiodiplodia. ii) Disease control during the nursery stage and the early stage after planting. This field involves epidemiological and disease management studies and involves the following pathosystems of tomato/ Fusarium solani/Clavibacter michiganensis; Cucumber/Pythium. Since 2011, Omer has been involved in pyrolysis/biochar projects, leading the studies of biochar as a tool to suppress soilborne pathogens. Methods used include classic and molecular tools, epidemiology and statistics, metagenomics, soil and plant inoculation with microorganisms.

Soil Science & Plant Nutrition

Uri Yermiyahu, Ph.D., is a Senior Researcher at the Agricultural Research Organization (Volcani Center) of Israel. His Ph.D. is from The Hebrew University of Jerusalem. Uri is the founder and director of the ICL-ARO Center for Fertilization and Plant Nutrition, and previously was the head of the Gilat Research Center. Since September, 2019 he has been serving as the Director of Research and Development for the Volcani Center.
Dr Yermiyahu’s research interests focus on plant nutrition and fertilization of crops. His contributions include understanding influences of plant nutrition on biotic and abiotic stress causing factors, mineral requirements in agriculture in desert environments, salinity and toxicity in plants, and managing nutrients as a function of irrigation water quality. He has worked with brackish, recycled and desalinated water and with horticultural crops ranging from fresh herbs and flowers to vegetables and fruit trees

Entomology

Ally Harari, Ph.D., joined Volcani’s Department of Entomology in 1999. Her expertise comprises the manipulation of sexual behavior and mating systems of insects and spiders, and environmental manipulations to combat insect pests and invaded weeds. Her research strategies combine theory and applied approaches in the search for environmentally friendly solutions to agricultural pest management with the ultimate goal to reduce the damage caused by various pests through the exploitation of the pests’ reproductive systems and use the reproductive system of beneficial arthropods to fight insect pests and invasive weeds. Currently, Ally’s research is focused on four major areas: (1) The effect of volatile communication on reproductive decisions of arthropod pests. (2) Manipulating reproductive decisions of insect pests. (3) Biological control of invasive weeds and its application in agricultural practices, and (4) Encouraging natural arthropod diversity as a tool in pest management.
