Shortage of water availability and awareness of the need for sustainable resource management have generated a significant increase in the use of recycled water for irrigation and processing of crops and harvest products, respectively. As a result, irrigation systems face the challenge of neutralizing plant pathogens to reduce the risk of their disp...
Article
Demand for conservation and recycling of water has increased significantly. Therefore irrigation water used for horticultural or agricultural purposes needs to be treated before being reused to eradicate plant pathogens and thereby reducing the risk of pathogen dispersal and losses due to disease. The economically important fungal plant pathogens F...

In zirkulierenden Bewässerungssystemen kann es zu einer Anreicherung und Verbreitung von Phytopathogenen kommen. Dies macht phytosanitäre Maßnahmen notwendig. Im Rahmen dessen wurde das System zur elektrolytischen Wasserdesinfektion in Gewächshäusern [SeWiG] entwickelt. Da beim Einsatz dieser Methode unter anderem Chloratanionen als Nebenprodukt en...

Los virus fitopatógenos afectan en gran medida la producción agrícola colombiana. Diferentes estudios indican que las pérdidas económicas causadas por estos problemas fitosanitarios podrían evitarse teniendo un mejor conocimiento de estos patógenos y empleando un procedimiento estándar de manejo preventivo como guía. Los productores, viveros, comer...

The increasing use of recirculating nutrient solutions and drainage water for irrigation purposes requires effective sanitation methods to minimise the dispersal of plant pathogens. Among these, plant viruses are of particular interest because they cannot be cured. A new disinfection system was tested in regard to its ability to inactivate plant vi...

Bei der Nutzung von Oberflächenwasser zur Bewässerung und einer Wiederverwendung des überschüssigen Wassers ist das Verbreitungsrisiko von Pflanzenkrankheitserregern erhöht. Dies bedingt eine effektive Wasserdesinfektion. Hierzu wurde zunächst in vitro die Wirksamkeit einer durch Salzelektrolyse erzeugten Desinfektionslösung zur Inaktivierung von p...

Verschiedenste Methoden wurden bisher auf ihre Eignung zur Minimierung der Ausbreitung von Pflanzenpathogenen in rezirkulierenden Wassersystemen geprüft. Zu diesen gehören die Langsamsand-/Lavagranulatfiltration, UV-Bestrahlung, Erwärmung, Ozonierung, der Zusatz nichtionischer Tenside und das Chloren. Während einige Methoden pathogenabhängig eine h...

The experiment was conducted during the first semester of 2010 in the greenhouses of the Agronomy Faculty, Universidad Nacional de Colombia, Bogota, with 21°C and 60% for the average temperature and relative humidity, respectively. The effect of increasing NaCl concentrations in the irrigation water, 0, 30, 60 and 90 mM (electrical conductivity of...

Tested in experimental scale, an innovative system for electrolytic water disinfection in greenhouses (SeWiG) was very efficient. With scaling up this system for industrial greenhouses, the new technology will be tested, validated and optimized under practical conditions. This is necessary for a successful launch to the sector of plant production under glass. The special feature of the new system for electrolytic water disinfection is the functional superiority over common methods like filtration, ultraviolet irradiation, heating, ozonation or chlorine dioxide. Worth highlighting is its high effectiveness against plant viruses and the reduced risk for users, plants and the environment.
