| Abstract:
The spread of several plant viruses by recirculating nutrient solutions of the ebb-flow irrigation system was studied and how far viruses are released from roots of diseased plants while contaminating the irrigation water and infect healthy plants. The experiments were concentrated on some stable viruses that are often found in horticultural crops and may cause serious yield losses. All tested viruses can be transmitted by recycled water and infect healthy plants within a few weeks. Most pathogens in water are detectable directly by ELISA (ArMV, CGMMV, CMV, PLCV, TMV, TNV, ToMV and TSWV). Water contaminated by PLPV has to be ultraconcentrated before serological assay. It is remarkable that TSWV is easily transmitted by water and detected by ELISA non concentrated, because the virus is not stable and difficult to inoculate mechanically to hostplants. | |
