Once inside the plant, one of three main attack strategies is deployed specific feature of interaction given;

A) Necrotrophy

B) Biotrophy

C) Hemibiotrophy

i) where the plant cells remain alive throughout infection

ii) where the plant cells are killed in advance of infection 

iii) extensive plant tissue damage at initial stages

iv) where the pathogen initially keeps cells alive but at later stages of the infection, kills them
