INTRODUCTION OF COURSE

This course introduces the students with concept and understanding of allelopathy. It includes information about allelopatic plants, types of allelochemicals those plants release, and their modes of actions. This course describes the role of allelopathy in agro-ecosystem. It also explains, how allelopathy can be used to combat against insects, pests, diseases and their management.

LEARNING OUTCOMES

Key course objectives are:

  • To introduce the students with the basic concept and definition of allelopathy, allelochemicals, allelopatic plants, types and mode of actions of allelochemicals.
  • To elaborate the importance and role of allelopathy in agro-ecosystem.  
  • To develop an understanding of using allelopathy as a tool for agricultural pest management.
  • Acquaint the students with the knowledge of using allelopathy, a way forward to enhance crop productivity.
  • To familiarize students with recent research, trends and advances in the field of allelopathy.
