Abstract

Four different patterns of symptoms were observed and collected in four Fig- growing areas of north Egypt from cv. Sultany farms . Fig mosaic virus was transmitted by an Eriophyid mite, Aceriaficus Cotte . Young leaves appearing typical symptoms caused by FMV. Electron microscope observations of ultra- thin sectioned tissues from symptomatic leaves showed double membrane bodies (DMBs) characteristic for FMV particles. The size of the PCR amplified fragment was 302 bp. The genetic relationship between the RdRp gene for the Egyptian isolate of FMV with other FMV isolates on the gene bank was studied. In the present study, we demonstrated the efficiency of two in- vivo experiments including pre and post treatmen ts from inoculation using four different medical plant extracts against the FMV confirmed by RT- PCR , infection percentage and disease severity. Individual treatments with ginger and turmeric extracts in pre inoculation experiment and Thuja following Harmal extracts in post inoculation experiments were showed that the inhabitation affect against symptoms development.
