Head: Amit Gal-On, Ph.D.
Staff
Research in the Department of Plant Pathology and Weed Research focuses on fungal, bacterial, viral pathogens and weeds causing damage to agricultural crops in Israel and abroad. The central goal of this Department is the production of knowledge and the development of technologies to control diseases and weeds, while maintaining the quality and security of agricultural produce and minimalizing adverse environmental effects.

Vision of the Department
The vision of the Department is to lead research and technology in managing damage to crops while maintaining the values of sustainable agriculture and quality production.

Goals of the Department

  1. Increasing understanding of the relationships between crops, crop damage and environmental conditions.
  2. Identifying the problems limiting agricultural production related to Plant Protection.
  3. Development of efficient, environmentally-friendly methods for solving problems limiting agricultural production.
  4. Distribution and absorption of knowledge and methods that have been developed for the benefit of growers and industry in Israel and abroad.
  5. Maintaining knowledge for developing the next generation of research, development and practical applications in Plant Protection.

Selected trends of research in the Department

Development of management and preventive approaches to plant diseases 

  • Epidemiology of disease-causing agents.
  • Development and application of methods for assessing susceptibility to disease-causing agents.
  • Development of plant resistance through various methods, including conventional genetics and genetic engineering.
  • Development and use of grafted plants as an instrument for preventing the transmission of soil-borne diseases.
  • Testing and development of biological and other non-chemical methods.
  • Development of integrated control principles, including system-support decisions, for control of disease agents, combined with intelligent use of chemical methods.
  •  Development of precision agriculture approaches for weed control based on models and sensors for weeds, in time and space.

 Research in the physiology of plant disease and plant/pathogen interaction

  • Characterization of the pathogenesis process, understanding the mechanisms of pathogen attack, and identification and isolation of pathogenicity genes involved in the process of disease development.
  • Characterization of the infected plant response, identification and isolation of the genes involved in plant response to disease agents.

Weed research and developing methods of minimalizing the spread and damage caused by weeds 

 

  • Improving understanding of the biology and physiology of parasitic weeds.
  • Biological control of weeds.
  • Intelligent chemical control of weeds.
  • Developing herbicide-resistant crops.
  • Developing parasitic-weed resistant crops.
  • Improved, efficient diagnosis of broomrape in crop fields.
