The Emergence of New Phytopathological Diseases Due to Climatic Changes

The emergence of new phytopathological disease is of great concern in line with the continuous changing climatic ecosystem associated with industrialization and urbanization. Plants respond differently to biotic (diseases) and abiotic factors (climatic factors). Climatic changes alter the infection cycle of most plant pathogen weather monocyclic or polycyclic. However, understanding the impacts of such changes on disease manifestation is of greater importance. This paper aims to explore reported cases and influence of new emerging phytopathological diseases as relative to climatic changes. The paper emphasizes understanding the development of new diseases under continuously changing temperature, level of carbondioxide, moisture level and relative humidity amongst others. The effects of climatic changes on the general plant photosystem are also explored. The paper concludes with management strategies employed by countries to mitigate pathogen emergence such as establishment of regulatory measures and quarantine bodies and phytosanitary.
