Abstract
Plant virus causes many important plant diseases and are responsible for huge losses in crop production and quality in all parts of the world, and consequently, agronomists and plant pathologists have devoted considerable effort toward controlling virus diseases. One the most important virus on many Prunus species, causing great economic losses is Plum pox virus (PPV),casual agent of Sharka disease. Since its discovery, Sharka has been considered as a calamity in stone orchards. The virus has been detected in almost every country where any significant commercial stone fruit cultivation occurs [1]. The virus is entered into the list of regulated pests common in Ukraine. In Ukraine, the total area of PPV spread totals 4013,2764 ha. In Odessa region, 18.5 ha districts are in PPV quarantine. Six hotbeds of PPV infection totalling 28 hectares were found in Odessa region. For the first time in Odessa region, PPV was found on cherry trees. Peach and plum trees are hit equally. In this study, we use geographic information systems technology to identify potential locations in a Odessa region for controlling the spread of Plum pox virus. To our knowledge, this is the first attempt to employ GIS technology for controlling plant diseases in Ukraine. Provided it is properly maintained, the geospatial data, and the ability to generate detailed maps with it, is key to the success of PPV containment. Information management will be a key to improving for controlling the spread of Plum pox virus.
Highlights
Plant viruses are group of pathogens that cause important loses in different fruit croups and they have great economic importance
This work was aimed at conducting Sharka disease monitoring of planted stone fruit crops in Odessa region using traditional visual, serological and molecular methods, and subsequent coupling of obtained data on virus spread with geographical information system (GIS) technology for further use by plant quarantine services, virologists and producers
Results and discussion.In 2014-2015, for the first time in Odessa region, Plum pox virus (PPV) was found on cherry trees (Fig. 2) in Khlebodarskoye village of Ovidiopol district
Summary
Plant viruses are group of pathogens that cause important loses in different fruit croups and they have great economic importance. This is especially true for diseases associated with vectored pathogens such as PPV, an aphid transmitted virus. Plum pox virus(PPV) is one of the most important pathogens causing destructive viral diseases in stone fruit trees such as peach, plum, apricot and cherry. It has spread to South and North America and Asia [3]. For domesticated Brassica plants, TuMV is considered one of the most damaging and economically important viruses [2]. In the study reported here, we describe the importance of preventive measures for the control of wide-spread and damaging pathogen of brassicas
