What is plant disease??
What is plant disease?? Definition of Plant disease An impairment of the normal state of the plant that modifies its vital functions The organism that cause disease are called pathogens e.g. bacteria ,viruses ,protozoa etc. The study of disease condition is called pathology
Difference between healthy and disease plant
Healthy plant Sick/ diseased plants Difference between healthy and disease plant Normal physiological functions e.g. Normal cell division ,differentiation and development Absorption of water and minerals from the soil and translocation Photosynthesis Reproduction A plant would not have all these functions

Classification on the basis of cause
Classification on the basis of cause Infectious disease A disease that is caused by pathogen which spread from diseased plant to a healthy plant Non infectious disease Disease which that is caused by non living organisms
On the basis of occurrence and geographical distribution:
On the basis of occurrence and geographical distribution: e.g. wart disease of potato e.g. rust, mildews e.g. leaf blight
