Abstract :

The water is the most critical factor for survival of all organisms. Vitality of plants depends on existence of water as it is the case for humans and animals. Cleanness and healthiness of water used for plants is as important as cleanness of water used for human health. Many microorganisms may be found in different water sources and cause microbial pollution. Viruses also important water polluting agents. However, when compared with human health, viruses causing infection in plants are of secondary importance and many different plant pathogenic viruses can be found in different water sources and may be carried by water. Therefore, water utilized for agricultural and irrigation purposes should be clean and and pathogen free. So, certain precautions are needed to be taken in order to eliminate infection sources of plant pathogenic viruses. This article discusses pollutions created by plant pathogenic viruses in different water sources, detection and identification of water-borne viruses, and hygienic characteristics of nutrient solutions used particularly for hydroponic culture and emphasizes control measures against possible infections.
