PLPA 504 : Plant Disease Management (Compulsory)

               Credit hour: 3

Concept and principles of plant disease management. Control of plant diseases through integration of cultural, physical, chemical, biological, host resistance  and legislative methods. Principles and components of biological control. Modern approachs of biological control: Black box and Silver Bullet approach. Formulation of bio control agents. Principles and practices of plant qurantine. The groups and mode of action of fungicides. Management of fungicide resistance. Plant defence strategies and mechanisms. Development of host resistance through conventional breeding. Development of transgenic crops through bacteria mediated gene transfer. Integrated approaches for plant disease management and cost benefit analysis.


PLPA 505: Clinical Plant Pathology (Compulsory)

              Credit hour: 3

Requirements of Plant Pathology Clinic. Technical procedures, material requirements and organizational set up for the effective operation of a plant clinic. Diagnostic process: from field observation and collection through to methods of culture, microscopy, keeping records and reference material. General laboratory practice and equipment maintenance. Collection, preservation and preparation of plant disease specimen for clinical studies. Maintenance of pure cultures of plant pathogens. Evaluation of antipathogenic chemicals. Frequent field trips to experimental stations and farmer’s field. Field observation on plant disease vegetable crops, field crops and fruits. Plant disease survey, detection and evaluation methods.


PLPA 506: Molecular Biology of Host- Pathogen Interactions (Compulsory)

               Credit hour: 3

Analysis of current concepts in the physiology, biochemistry, genetics and molecular biology of plant pathogen interactions. Microbial trophic strategies e.g. biotrophy, necrotrophy, symbiotic and virus interactions with plants. Molecular and biochemical basis of plant defence mechanisms, disease resistance including secondary metabolites and antimicrobial proteins.Mechanisms and strategies by which pathogens invade plants, overcome host defense responses and reproduce in or on the host tissues.Mechanisms and strategies by which symbiotic organisms interact with plants.Importance of fundamental molecular knowledge on these biological processes in improving control measures, by novel non-toxic chemicals or genetic modification. Basics molecular biology, molecular tools, chemicals, PCR, primer, gel electrophoresis.
