Uittreksel

Little cherry disease, caused by the viruses LChV-1 and LChV-2, is a serious and feared disease in commercial cherry culture. The first reports on the presence of Little cherry virus in Belgium date back to the early 1980s (Legrand et al., 1982). Yet, not much attention was given to its presence in the cherry culture till about 10 years ago, when economical damage in the orchards became evident but meanwhile also public awareness grew on the potential impact on the old long-stemmed cherry trees that form a valuable component of rural landscape and urban areas. Because non-European isolates of both viruses are included in the list of regulated organisms, the Belgian government also expressed its interest in a status report for these pathogens. Additionally, the cherry growers urged for more epidemiological knowledge and a firm strategy to address their economical loss due to the little cherry disease. In the framework of a 2 year research project, we collect information on the status of Little cherry virus 1 & 2 in Belgium. Additionally, specific epidemiological characteristics of the disease such as the presence of each virus in commercial sweet and sour cherry growing facilities in relation to the distribution of LChV-1 & 2 in ornamental Prunus trees, are also assessed. Attention also goes to the role that valuable landscape trees, e.g. the long-stemmed cherry trees in open spaces, play as reservoir for both cherry viruses. Are we dealing with several introductions ? What is the epidemiological risk for the grower when a neighbouring wild cherry tree in a private garden is infected by the little cherry disease ? As yet, literature mainly mentions the presence of LChV-1 in Western Europe, whereas only a limited spread (Poland, Germany) of LChV-2 is documented. Is this up to date information ? This presentation will focus on the mid-term results of the project, presenting the results of the survey conducted in cherry orchards, private gardens, in lane trees and individual landscape trees in Belgium during 2014 and the presence and distribution of LChV-1 and/or LChV-2 was assessed.
