18HO2023 NEMATODE PESTS OF HORTICULTURAL CROPS AND THEIR MANAGEMENT Credits 1:0:1 Course Objectives

 To study taxonomy, classification, and characteristics of plant parasitic nematodes  To learn about the role of nematodes in plant disease complex  To be familiar with principles of integrated nematode management

Course Outcome

At the end of this course, the students will be able to  Remember taxonomy, classification and characteristics of plant-parasitic nematodes  Explain role of nematodes in plant disease complex  Gain knowledge on Integrated nematode management

Theory
