The student knows about the early development & role of different micro-organism in development of plant disease.
The students gain knowledge on general concepts and classification of plant diseases The students have knowledge with general characteristics of fungi, bacteria, virus and mycoplasma like organisms causing plant diseases.
To acquaint the students with reproduction in fungi and fungal like organisms causing plant diseases.
On successful completion of this course and basing on the diversified course outcomes this course offers a good scope for students in employment sector.
