Abstract:

This study was conducted to evaluate the efficacy of foliar spray and irrigation by bion which induces systemic acquired resistance (SAR) in plant and determine the effect on Zucchini yellow mosaic virus in Cucurbita pepo L plant under field conditions. The study includes: Biological evaluation of virus by local lesion assay and serological evaluation by DAS-ELISA. Resultes of foliar spray and irrigation applications by Bion showed significant differences in Percentage of inhibition number of local lesions on chenopodium quinoa which were compared with control application (39.5). Serologically, DAS- ELISA values under 405 nm also showed significant differences compared with the control (1.41). foliar spray application by 2mM of bion was given the better results in inhibition of number local lesions (58.73%) and reduction of virus replication (68.08%) compared with all treatments. These finding suggested efficiency bion in enhancement systemic acquired resistance in squash plants against ZYMV under field conditions.
