Following are certain strategies used by pathogen to attack over the host plant that describe plant-pathogen interactions:

                      I                                                                                             II

A. Necrotrophic pathogens                              i) most of the plant tissue remains alive and only minimal cell damage can be observed, as the pathogens feed on substrates provided by their host

B. Biotrophic pathogens                                 ii) In which the host cells are kept alive as described for biotrophic  Pathogens and followed by a necrotrophic stage, in which the pathogens can cause extensive tissue damage

C. Hemibiotrophic pathogens                         iii) attack their host by secreting cell wall–degrading enzymes or toxins, which eventually kill the affected plant cells, leading to extensive tissue maceration. This dead tissue is then colonized by the pathogens and serves as a food source
