Abstract: Eggplant (Solanum melongena) is an important vegetable and widely cultivated in polyethylene covered houses in Iraq. A new virus, Eggplant blister mottled virus (EBMV), was isolated in previous study, from naturally infected eggplant and was characterized as potyvirus. The virus is considered now as the most important virus infecting eggplants and causing heavy damage to yields. This study was conducted to evaluate the effect of three products, Vit-org nutrient, 2-nitromethyl phenol, and Thuja extract on the multiplication of EBMV in eggplants. Results of the study showed that the application of the three products on EBMV-inoculated eggplants at 2.5 and 1 mlL, and 6 gL caused a reduction in ELISA reactions absorbance to 0.073, 0.091, and 0.092, respectively, which reflect a reduction in virus concentration. The application of the products on eggplants at the same concentrations followed by virus inoculation, after 24 h of protecting the plants against virus infection for 18, 10 and 12 days, respectively accompanied by retardation of symptoms development in 26, 16 and 20 days for the three products, respectively. The treated eggplants neither developed visible symptoms nor contained detectable concentrations of virus during these periods. Vit-org nutrient was found to be more efficient in protecting the plants against EBMV in both post and pre-applications.[...] Read More.
