Zlata Štefanac ; Hrvatska

Abstract

Onion yellow dwarf virus (OYDV), the cause of a harmful disease of onions (Allium čepa L.) and shallots (A. ascalonicum L.) was found and identified on these species in Yugoslavia. The survey of samples of onion bulbs and onion sets from Turopolje, Sombor (Bačka) and the island cf Rab on the presence of symptoms during growth hap shown that OYDV occurs in all these onion growing regions but that differences in the rate of infection are considerable (cf. Table 1). In some inspected onion plots in the vicinity of Zagreb more than 50°/o of the plants were infected.
By mechanical inoculation and by Myzus persicae (Sulz.) OYDV was easily transmitted from onion to onion but it could not be transmitted from onion to leek (A. porrum L.).
The paper includes information concerning control of the disease.
