Most phytopathogenic fungi are [[Ascomycota|Ascomycetes]] or [[Basidiomycota|Basidiomycetes]]. They reproduce both [[sexual reproduction|sexually]] and [[asexual reproduction|asexually]] via the production of [[spores]] and other structures. Spores may be spread long distances by air or water, or they may be soil borne. Many soil inhabiting fungi are capable of living [[saprotroph]]ically, carrying out the partrole of their life cycle in the [[soil]]. These are facultative saprotrophs.
 
Fungal diseases may be controlled through the use of [[fungicides]] and other agricultureagricultural practices. However, new [[Race (biology)|races]] of fungi often [[evolution|evolve]] that are resistant to various fungicides.
 
Biotrophic fungal pathogens colonize living plant tissue and obtain nutrients from living host cells. [[Necrotroph]]ic fungal pathogens infect and kill host tissue and extract nutrients from the dead host cells.<ref>Yu. T Dyakov, Chapter 0 - Overview on parasitism, Editors: Yu, T. Dyakov, V.G.
