DESCRIPTION AND OBJECTIVES

Plant Disease Management course has been designed to acquaint the students with recent developments in the management of different plant diseases. In this course, the students will be taught about different types of resistance in crop plants, biological, physical and chemical control of plant diseases. The main objective of this course is to introduce the students about plant disease management practices.

INTENDED LEARNING OUTCOMES

At the completion of the course the students will be able to understand:

  1. About concepts and techniques of plant disease management.
  2. Principles and methods of plant disease management based on avoidance, exclusion, eradication of pathogens, protection (preventive and curative) and resistance (pathogen derived resistance, host resistance).

COURSE CONTENTS

Theory

  1. Principles and methods of plant disease management based on avoidance, exclusion, eradication of pathogens, protection (preventive and curative) and resistance (pathogen derived resistance, host resistance)
  2. Management of plant diseases with emphasis on regulatory, cultural, biological, physical and chemical strategies; integrated disease management (IDM) seed health certification system
  3. Philosophy of TOF (Training of Facilitators) and FFS (Farmer Field School)
  4. Epidemiological basis of disease management strategies, concept of field biodiversity, conservation and crop appraisal.

Practical

  1. Demonstration of different disease management practices
  2. Equipment and machinery used for disease management and their calibration; safety measures for disease managing chemicals; handling and application procedures
  3. Crop Agro Ecosystem Analysis.
