VIRUSES IN TULIP IN THE NETHERLANDS |

| Abstract:
The virus situation in tulip was studied extensively in the past decades. The tulip breaking syndrome was found to be associated with tulip breaking virus (TBV) without strain specification, tulip band breaking virus (TBBV) and tulip top breaking virus (TTBV). The differentiation of the viruses on the basis of symptoms in tulip, herbaceous host range, serology, and identification on molecular basis is described. Control of the virus spread was effective by mineral-oil and/or pyrethroid insecticide sprays. The incidence of tulip breaking, tobacco rattle virus (TRV), and tobacco necrosis virus (TNV) affected by weather conditions in winter and spring is indicated. The recurrence of symptoms of TNV in the replanted progeny largely differed in bulbs planted in sandy soil and heavy loam/clay soil types. The complexity of control of TRV is briefly dealt with and that of TNV more elaborately. The planting of the bulbs late in autumn appeared effective to escape from primary infection by TRV and TNV. The situation on the occasional diseases is briefly described, e.g., soil-borne 'Pseudo Augusta' virus (PAV), soil-borne tulip severe mosaic virus (TSMV), soil-borne tulip mild mosaic virus (TMMV), soil-borne tulip necrotic streak virus (TNSV), soil-borne Arabis mosaic virus (AMV), air-borne lily symptomless virus (LSV), and air-borne cucumber mosaic virus (CMV). The relationship of the tulip breaking viruses, e.g., TBV, TTBV, and TBBV, with viruses known from literature, e.g., tulip chlorotic blotch virus (TCBV), WaT-virus, TuM-virus L2, and lily mottle virus (LMV; TBV-lily) is discussed. | |
