DESCRIPTION AND OBJECTIVES

The key objective of this course is to study basic and applied aspects of economically important diseases of fruit and ornamental plants and their management.

After completing this course the students will be aware of:

  1. Economically important diseases of fruits.
  2. Management strategies for different diseases.
  3. Disease cycles and epidemiology of fruit diseases.

INTENDED LEARNING OUTCOMES

All fruits occupy a specific area of cultivation throughout the world. Chief among them is mango, banana and citrus. Other fruits of importance are guava, papaya, apple, strawberry and pomegranates. The importance of fruits in human diet cannot be overemphasized because of their high nutritional value. The total production of fruits can be doubled if adequate attention would be given to proper cultivation practices and to control of diseases. After attending this course, students have better understanding of major pathogenic diseases occurring in fruits orchard and their management strategies.

COURSE CONTENTS

Theory Importance, symptoms, disease cycle, methods of perpetuation; management of major diseases of tropical (banana and papaya), subtropical (guava, mango and citrus) and temperate (pome, stone and nut fruits, grapes) fruits and common ornamental plants.

Practical Field visits, collection and preservation of diseased specimens; Identification of diseases on the basis of symptoms; isolation of pathogens and preparation of permanent mounts; orientation with management practices.
