    PLANT PATHOLOGY AND MICROBIOLOGY

     

    CO81: Collect, consolidate, and synthesize data pertaining to the cellular biology, diversity, reproduction, ecological & economic ramifications, and interactions with hosts of Bacteria, Viruses, and Phytoplasma and contributions of eminent scientists.

    CO82: Critically examine the complexities of fungal characteristics, encompassing heterothallism and parasexuality, and demonstrate adeptness in the identification and classification of fungal species. Additionally, devise innovative strategies for fungal management and applications in agriculture, medicine, and ecology

    CO83: Apply taxonomic principles and life cycle analysis techniques to identify and classify key fungal specimens & develop solutions for fungal disease management, biocontrol, and sustainable agriculture practices.

    CO84: Demonstrate a comprehensive understanding of symptomatology, causal organisms, and disease cycles of viral, phytoplasmal, and nematodal diseases. Furthermore, formulate disease management programs integrating cultural, biological, and chemical measures for advanced problem-solving abilities.

    CO85: Develop expertise in diagnosing bacterial and fungal plant diseases & understand their etiology, pathogenesis and management and propose sustainable disease management practices.

    CO86: Contribute effectively in course-specific interaction.
