“…Results showed that BtMV was readily mechanically transmitted by sap extracted from infected sugar beet leaves using fore finger with (Phosphate buffer pH7.2 and carborandum 600 mesh) to healthy plants as described before. These results were in accordance with that reported by Bennett, (1965); Howell and Mink, (1971); Lewellen, (1973) ;Polak, (1981); Katis et al, (1997); Dusi and Peters, (1999) and Mali, (2000), Omer, et al, (2006 and Haggag Wafaa et al, (2010).…”

“…(3), it could be observed that, BtMV reduce the measurements of Average (Av) of ( Medvein thickness, Blade thickness, Palisade tissue thickness, Spongy tissue thickness, Vascular bundles length, Vascular bundles width, Number of xylem vessels and Xylem vessel diameter). Like results were noticed by Singh and Rathi (1996) and Mali (2000) . Semi thin sections of healthy and infected leaves were scanned after staining with fast green by light microscopy.…”

“…BtMV is spread by Myzus persicae Sulz in non-persistent method (Mali, 2000 andOmer et al, 2006). BtMV was also transferred by Aphis fabae Scop (Polak, 1981;Dusi and Peters, 1999).…”

The objective of the study described in this paper was to isolate and determine a range of a potyvirus in sugar beet crop. The virus inoculum was taken from obviously diseased sugar beet plants (Beta vulgaris L.cv. Top), screening mild to severe mosaic complemented with leaves malformation and distortion, suspected to be caused by virus infection. Leaf samples were togethered from different areas in Menoufia Governorate, Egypt. The determination of the isolate was based on symptomatology, host range, modes of transmission (mechanicalinsect), serological tests (Direct ELISA, DBIA and TBIA), light microscopy. BtMV infection distributed some of photosynthetic pigments in infected beet leaves, i.e. chlorophyll, carotenoids and also reduced the concentration of total carbohydrates and total sugar in roots. Currently, different inducers stemmed from several materials were used to decrease the virus concentration. Preliminary showing were actual in reducing the number of local lesions formed by challenge inoculation of BtMV. Both inducers (plant extracts and Salicylic acid (SA) showed reducing in the total numbers of local lesions and concentration of the virus. Among the inducers used for introduction of resistance against BtMV, Dianthus caryophyllus extract was found to be most effective. Also, Our results revealed that Salicylic acid (SA) used for screening was effective in reducing the concentration of virus and the number of local lesions formed by the challenge inoculation of BtMV .
