Abstract
Sharka, caused by the Plum Pox Potyvirus (PPV), is the most devastating disease of stone fruits. In susceptible varieties this disease can cause high yield losses and tree decline. The fruit quality is also effected. The disease is widely spread in Slovenia. In the year 2000 Slovenia issued the decree about the measures for prevention of sharka spead. The decree includes systematic survey and very strict measures if the infection with PPV is detected. The decree only pescribes screening hosts from the genus Prunus, but many other hosts of the Plum Pox Potyvirus are known, including many woody and herbaceous, perennial an annual host, cultivated plants and weeds. The data on importance of hebaceous and the weed plants for sharka spread are scarce, although some authors consider annual plants to be a continuos source of infection for fruit species. The Plum Pox Potyvirus is transmitted by insects in a non-persistent manner. For the determination of the role of weed plants for sharka spread the transmission efficiency from weeds to cultivated plants by individual vectors is crucial. The literature data on this topic are also scarce. In spite of strict measures sharka is spreading also in the areas where infected Prunus hosts were removed. Due to the economic importance of sharka disease and for the effective prevention of the disease spread it is thus necessary to establish the role of weeds for sharka spread in Slovenia. In the frame of the project following topics will be studied:- the range of PPV infection of weeds, predominant in Slovene stone fruit orchards- the presence of vector insects;- the PPV infection of vector insects, predominant in Slovene stone fruit orchards - the transmission ability of predominant vectors for transmission from weeds to stone fruit cultivars and vice versa.
